Ingestion of Lilium or Hemerocallis spp. by cats can result in renal failure. The objectives of this study were to determine the foreknowledge of lily toxicity of owners of cats that were exposed to lilies and to obtain historical, clinical and outcome information on the exposures. A survey was done of cat owners reporting indoor exposures to lilies to the Animal Poison Control Center (APCC) during April 2009. Forty eight individuals, (57 cats) were included. Sixty nine percent of cat owners said they could recognize a lily and 27% knew that lilies were toxic prior to their cats' exposures. Most lilies were obtained from grocery or other stores, and were purchased by the owners or as gifts to the cat owners. Owners who were unaware of lily toxicity frequently left the flowers where the cats had access to them, whereas in households where the toxicity was known the cats actively sought out the flowers. Of the cats in this study 93% received prompt veterinary care, and 87% either developed no signs or had brief signs that resolved. Five percent had evidence of renal insufficiency at final follow-up and another 5 percent of cats were euthanized due to renal failure.  相似文献

Lilies are commonly kept flowering ornamental plants that are used in holiday celebrations, weddings, and funerals, and in various floral arrangements. Lilies of genera Lilium and Hemerocallis (day lilies) have been shown to cause nephrotoxicity in cats. Confusion arises because so many different plants are called lilies. Members of the genus Convallaria (lily of the valley), while sparing on the kidneys, elicit toxic effects because they possess potent cardiac glycosides similar to digitalis. Even more confusing as to which lilies are toxic is the fact that many hybrids exist. The majority of the public do not know that lilies can be dangerous to cats and, in fact, cannot correctly identify the plants in their own homes. Cats have been shown to be extremely sensitive to the toxic effects of lilies. As little as 2 leaves or part of a single flower have resulted in deaths. It should be pointed out that the whole plant-petals, stamen, leaves, and pollen are toxic. The exact toxic dose and the precise toxins responsible for renal damage are currently unknown. The quick onset of clinical signs suggests a rapid absorption rate of the toxin. The renal tubular epithelium appears to be the target of the toxin. Studies indicate that it is the water-soluble fraction of the lily that is nephrotoxic. In cats, clinical signs of lily intoxication include salivation, vomiting, anorexia, and depression. Polyuric renal failure leads to dehydration and anuric renal failure and death results. No analytic verification of lily ingestion is currently available. Successful treatment includes initiation of fluid diuresis before the onset of anuric renal failure. Once anuria develops, peritoneal dialysis or hemodialysis is the only potential treatment. Differential diagnoses of lily poisoning include any potential cause of acute renal failure in a cat. Prognosis is excellent if fluid diuresis is started before anuric renal failure has developed. The public must be made aware of potentially toxic ornamental house plants.  相似文献

OBJECTIVE: To determine clinical characteristics, treatments, and outcome in dogs and cats evaluated after submersion in freshwater. DESIGN: Retrospective case series. ANIMALS: 25 dogs and 3 cats. PROCEDURES: Medical records were reviewed for signalment; causes, location, and month of submersion; physical examination findings at admission; results of blood gas analysis; treatments administered; duration of hospitalization; and outcome, including evidence of organ failure or compromise. RESULTS: All submersions involved bodies of freshwater. Fourteen animals were submerged in man-made water sources, 13 were submerged in natural water sources, and the body of water was not recorded in 1 case. Twenty (71%) submersions occurred from May through September. Cause was identified in 16 animals and included extraordinary circumstances (n = 6), falling into water (5), breaking through ice (3), and intentional submersion (2). Twelve animals were found submerged in water with unclear surrounding circumstances. Treatment included administration of supplemental oxygen, antimicrobials, furosemide, corticosteroids, and aminophylline and assisted ventilation. Respiratory dysfunction was detected in 21 animals. Neurologic dysfunction was detected in 12 animals, hepatocellular compromise was detected in 6 animals, and cardiovascular dysfunction was detected in 4 animals. Three dogs had hematologic dysfunction, and 2 dogs had acute renal dysfunction. Eighteen (64%) animals survived to hospital discharge, but all of the cats died. In 9 of 10 nonsurvivors, respiratory tract failure was the cause of death or reason for euthanasia. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that submersion is an uncommon reason for veterinary evaluation but is associated with a good prognosis in dogs in the absence of respiratory tract failure.  相似文献

OBJECTIVE: To determine indications for and outcomes of positive-pressure ventilation (PPV) in cats, document ventilator management, and identify factors associated with outcome. DESIGN: Retrospective study. ANIMALS: 53 cats that underwent PPV. PROCEDURE: Information on signalment, history, concurrent diseases, clinical findings, results of venous blood gas analyses and clinicopathologic testing, treatment, ventilator settings, and outcome was retrieved from the medical records. Data for cats that survived were compared with data for cats that died or were euthanatized while undergoing PPV RESULTS: PPV was initiated for management of respiratory failure (36 cats [68%]), cardiac arrest (9 [17%]), neurologic impairment (6 [11%]), and nonresponsive hypotension (2 [4%]). Eight cats (15%) survived, 19 (36%) died, and 26 (49%) were euthanatized while undergoing PPV. Cats that survived had a longer duration of ventilation than did those that died or were euthanatized and had a significantly higher incidence of ventilator-associated pneumonia. Signalment and ventilator settings were not associated with outcome. Cats that had no clinical evidence of pulmonary disease but required PPV because of primary neurologic disease had a higher survival rate (2/6) than did cats that required PPV because of respiratory failure (5/36), cardiac arrest (1/9), or nonresponsive hypotension (0/2). CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that the survival rate for cats requiring PPV may be lower than reported survival rates for dogs. Death was attributable to progressive respiratory failure, non-responsive hypotension, kidney failure, or neurologic impairment.  相似文献

Renal transplantation was performed as treatment of end-stage renal failure in 23 cats. Twenty-two cats had chronic renal disease and 1 cat had acute renal disease associated with ethylene glycol-induced toxicosis. Sixteen cats were discharged from the hospital. Nine survived a mean of 8.4 +/- 6.5 months, and 7 cats continue to survive at the time of this report (mean 12.6 months). Seven cats died within 2 weeks of surgery. All renal allografts were obtained from unrelated blood-crossmatch-compatible donors. No deaths were attributable to acute renal allograft rejection, demonstrating the successful maintenance of renal allografts by use of cyclosporine and prednisolone immunosuppression in cats.  相似文献

The effect of 3rd-degree atrioventricular block on long-term outcome in cats is unknown. Clinical findings and long-term outcome of 21 cats with 3rd-degree atrioventricular block were studied retrospectively. Median age of cats studied was 14 years (range 7-19 years). Presenting signs included respiratory distress or collapse, but 6 cats had no clinical signs of disease. Eight cats had congestive heart failure (CHF) at the time that 3rd-degree atrioventricular block was detected. Heart rates ranged from 80 to 140 beats per minute (bpm; median 120 bpm) with no difference in heart rate between cats with and those without CHF. Eleven of 18 cats that had echocardiograms had structural cardiac disease, and 6 cats had cardiac changes consistent with concurrent systemic disease. No atrioventricular nodal lesions were detected by echocardiography. One cat had atrioventricular nodal lesions detected on histologic examination. Median survival of 14 cats that died or were euthanized was 386 days (range 1-2,013 days). Survival did not differ between cats with or without CHF or between cats with or without structural cardiac disease. Thirteen cats with 3rd-degree atrioventricular block survived > 1 year after diagnosis, regardless of presenting signs or underlying cardiac disease. Third-degree heart block in cats is often not immediately life threatening. Survival was not affected by the presence of underlying heart disease or congestive heart failure at the time of presentation. Even cats with collapse might survive > 1 year without pacemaker implantation.  相似文献

OBJECTIVE: To evaluate outcome of renal transplantation in dogs administered cyclosporine, azathioprine, and prednisolone immunosuppression. STUDY DESIGN: Prospective clinical study. ANIMALS: Fifteen dogs with chronic renal failure. RESULTS: Nine dogs died within 1 month of surgery; 5 died from complications associated with generalized thromboembolism. Three dogs survived for 6-25 months. Three dogs alive at the time of this report have survived 22-48 months; however, all 3 dogs have had bacterial infections that responded to antibiotic therapy. There was no biochemical evidence of acute allograft rejection in any dog. Perioperative use of enoxaparin may have prevented thromboembolism in 5 dogs. CONCLUSIONS: Triple drug immunosuppressive therapy used in this study prevented acute renal allograft rejection in 6 dogs that survived >4 weeks; however, immunosuppression was excessive, resulting in an unacceptable frequency of infection and other drug-related complications. Perioperative anticoagulation therapy seem to be warranted. CLINICAL RELEVANCE: Survival time and quality of life for this group of dogs was poor; however, there was no evidence of acute rejection in the dogs surviving >4 weeks. This protocol should only be used if the degree of immunosuppression is reduced, and early evidence of allograft rejection is monitored by renal biopsy or markers of lymphocyte activation.  相似文献

The objectives of this study were (1) to evaluate the indications, complications and outcomes of multiple red cell transfusions (MrcTs) in cats; of these cats (2) to describe those that received massive transfusion and (3) compare them with those who received MrcTs over a longer time course. Twenty-seven cats were identified which received a total of 110 transfusions, with a median of three transfusions (range 3-15) per cat. The transfusions consisted of 47 units of whole blood and 63 units of packed red blood cells. The median age of cats was 6 years (range 6 months to 15 years). Cats were hospitalized for a median of 6 days, with a range of 1-38 days. No acute transfusion reactions were documented, although due to the critical nature of the cats, they may not have been appreciated. Sixteen cats survived to discharge and 11 died or were euthanased. Indications (and % survival) for transfusions included bone marrow failure (n=8; 50%); surgical loss (n=4; 100%), sepsis (n=3; 0%), neoplasia (n=3; 33%), acute renal failure (n=3; 66%), trauma (n=2; 100%), gastrointestinal bleeding (n=1; 100%), and cats with multiple disease processes (n=3; 33%). MrcTs are well-tolerated in cats and may be associated with a favorable outcome.  相似文献

Information regarding the use and success of peritoneal dialysis (PD) in the management of acute renal failure (ARF) in cats is lacking. The purpose of this retrospective study is to describe the indications, efficacy, complications and outcome of cats undergoing PD for ARF. Six cats that underwent PD for treatment of ARF of various etiologies were included. PD effectively replaced renal function in all cats and allowed renal recovery in 5/6 cats. Five cats were discharged and one cat died. Complications were reported in all cats and included subcutaneous edema (n=5), hyperglycemia (n=4), dialysate retention (n=3), and hypoalbuminemia (n=3). A novel technique consisting of a Blake surgical drain and an intermittent closed suction system was used, which appears to be a viable option for PD in cats. Although complications are common, PD is an effective renal replacement therapy for ARF in cats and carries a reasonable prognosis in selected cases.  相似文献

Population characteristics, risk factors, and survival characteristics were evaluated in 74 cats with hypertrophic cardiomyopathy (HC) seen at North Carolina State University veterinary teaching hospital from 1985 to 1989, and compared with 82 clinically normal cats. The mean (+/- SD) age of cats with HC was 6.5 (4.0) years. Neutered males were at significantly greater risk (odds ratio 3.1) than neutered females. Breed, body weight, or coat color were not determined to be risk factors for HC. Tricolor cats were significantly underrepresented, probably reflecting the male predisposition for HC and not a true risk reduction associated with coat color. Forty-one cats were without clinical signs of heart disease (murmur and/or gallop sound only), 24 were in congestive heart failure, and 9 had systemic arterial embolism, 3 of which had concomitant congestive heart failure. The median survival time for 61 cats with HC, for which survival information could be obtained and that were not euthanatized on day 1, was 732 days. Survival was not affected by age at diagnosis, breed, body weight, or sex. However, clinical signs were important in determining prognosis; cats with heart rates greater than 200 beats/min survived significantly longer (median survival greater than 1,830 days) than those with heart rates greater than or equal to 200 beats/min (median survival = 152 days). Cats without clinical signs (median survival greater than 1,830 days) survived longer than those with clinical signs, and cats in heart failure survived a median of 92 days, compared with 61 days for those with systemic arterial embolism. Analysis of survival revealed no significant difference between the 2 groups of cats with clinical signs; however, all cats with embolism and only 60% of cats with heart failure were dead 6 months after diagnosis.  相似文献

OBJECTIVE: To determine clinical signs, results of diagnostic testing, underlying cause, and outcome in cats with seizures. DESIGN: Retrospective study. ANIMALS: 17 cats with seizures. PROCEDURE: Only those cats in which an underlying metabolic abnormality causing the seizures had been identified, diagnostic imaging of the brain and CSF analysis had been done, or a necropsy had been performed were included. Seizures were classified as being a result of metabolic disease, symptomatic epilepsy (ie, epilepsy resulting from a structural lesion of the brain), or probably symptomatic epilepsy (ie, epilepsy without any extracranial or identifiable intracranial disease that is not suspected to be genetic in origin). RESULTS: 3 cats had seizures associated with an underlying metabolic disease (hepatic encephalopathy), 7 had symptomatic epilepsy (3 with neoplasia and 4 with meningoencephalitis), and 7 had probably symptomatic epilepsy. Six of the 7 cats with symptomatic epilepsy died or were euthanatized within 3 months after the diagnosis was made, whereas 6 of the 7 cats with probably symptomatic epilepsy survived for at least 12 months after the diagnosis was made. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that cats with probably symptomatic epilepsy may have a good long-term prognosis.  相似文献

A study was conducted to assess the duration and the outcome (self-cure or death) of feline heartworm infection and the life expectancy of infected cats. To be included in the study, cats had to be positive for heartworm antibody (Ab) and heartworm antigen (Ag) and had to demonstrate the presence of worms by echocardiography. Self-cure was defined as (1) negative for heartworm Ag and (2) no further visualization of worms by echocardiography. Of the 1962 eligible cats, 364 (18.5%) were positive for heartworm Ag and 131 were positive for heartworm Ag and for echocardiography diagnosis (prevalence 6.7%). None of the cats was microfilaremic. Of 43 asymptomatic cats included into the follow-up study with owners' consent, 34 (79%) self-cured and nine (21%) died. Eleven (26%) cats remained asymptomatic and self cured within 21-48 months, 23 (53%) showed symptoms but self-cured within 18-49 months, 6 (14%) died within 8-41 months of follow-up and 3 (7%) suddenly died after 38-40 months, which was related to heartworm infection. The probability for death or sudden death increased significantly with age at diagnosis, but no difference was detected by gender, survival time after diagnosis, or the presence or absence of symptoms. The presence/absence of symptoms showed significant interaction with the age at diagnosis (i.e., symptomatic cats showed increasing duration of heartworm infection along with age at diagnosis compared to that for asymptomatic cats. Heartworm-infected cats survived significantly longer than heartworm-negative cats affected by hypertrophic cardiomyopathy, chronic renal failure, or neoplastic diseases.  相似文献

OBJECTIVE: To determine hepatotoxicity of stanozolol in cats and to identify clinicopathologic and histopathologic abnormalities in cats with stanozolol-induced hepatotoxicosis. DESIGN: Clinical trial and case series. ANIMALS: 12 healthy cats, 6 cats with chronic renal failure, and 3 cats with gingivitis and stomatitis. PROCEDURES: Healthy cats and cats with renal failure were treated with stanozolol (25 mg, i.m., on the first day, then 2 mg, p.o., q 12 h) for 4 weeks. Cats with gingivitis were treated with stanozolol at a dosage of 1 mg, p.o., every 24 hours. RESULTS: Most healthy cats and cats with renal failure developed marked inappetence, groomed less, and were less active within 7 to 10 days after initiation of stanozolol administration. Serum alanine transaminase (ALT) activity was significantly increased in 14 of 18 cats after stanozolol administration, but serum alkaline phosphatase activity was mildly increased in only 3. Four cats with serum ALT activity > 1,000 U/L after only 2 weeks of stanozolol administration had coagulopathies; administration of vitamin K resolved the coagulopathy in 3 of the 4 within 48 hours. All 18 cats survived, and hepatic enzyme activities were normal in all cats tested more than 4 weeks after stanozolol administration was discontinued. Two of the 3 cats with gingivitis developed evidence of severe hepatic failure 2 to 3 months after initiation of stanozolol treatment; both cats developed coagulopathies. Histologic evaluation of hepatic biopsy specimens from 5 cats revealed diffuse hepatic lipidosis and cholestasis without evidence of hepatocellular necrosis. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that stanozolol is hepatotoxic in cats.  相似文献

OBJECTIVE: To determine the incidence and prognostic significance of low plasma ionized calcium concentration in cats with clinical signs of acute pancreatitis (AP). DESIGN: Retrospective study. ANIMALS: 46 cats with AP and 92 control cats with nonpancreatic diseases. PROCEDURE: Medical records were reviewed, and results of clinicopathologic testing, including plasma ionized and total calcium concentrations, acid-base values, and electrolyte concentrations, were recorded. Cats with AP were grouped on the basis of outcome (survived vs died or were euthanatized), and plasma ionized calcium concentrations, acid-base values, and electrolyte concentrations were compared between groups. RESULTS: Serum total calcium concentration was low in 19 (41%) cats with AP, and plasma ionized calcium concentration was low in 28 (61%). Cats with AP had a significantly lower median plasma ionized calcium concentration (1.07 mmol/L) than did control cats (1.12 mmol/L). Nineteen (41%) cats with AP died or were euthanatized; these cats had a significantly lower median plasma ionized calcium concentration (1.00 mmol/L) than did cats that survived (1.12 mmol/L). Ten of the 13 cats with AP that had plasma ionized calcium concentrations < or = 1.00 mmol/L died or were euthanatized. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that low plasma ionized calcium concentration is common in cats with AP and is associated with a poorer outcome. A grave prognosis and aggressive medical treatment are warranted for cats with AP that have a plasma ionized calcium concentration < or = 1.00 mmol/L.  相似文献

The records of 25 dogs and 2 cats treated with peritoneal dialysis during an 11-year period were evaluated. The indications for peritoneal dialysis were acute renal failure in 21 animals, chronic renal failure in 5 animals, and azotemia of undetermined cause in 1 animal. Peritoneal dialysis resulted in a significant (P less than 0.05) decrease in serum urea nitrogen concentration in 19 of the dogs and a significant (P less than 0.05) decrease in serum creatinine in 20 dogs. The most common complication of peritoneal dialysis was hypoalbuminemia (11 animals affected). Other common complications were dialysate retention/catheter obstruction (8 animals), peritonitis (6 animals), hypochloremia (6 animals), and subcutaneous leakage of dialysate (6 animals). Twelve dogs and 2 cats died during treatment, 6 dogs were euthanatized, and 1 dog was lost to follow-up evaluation. The remaining 6 dogs survived and were discharged from the hospital after successful peritoneal dialysis. On the basis of the results of this study, the authors concluded that peritoneal dialysis, although associated with a high complication rate, was a successful technique for reducing azotemia in dogs with acute and chronic renal failure. Survival rates were poor because of the severity of the underlying renal diseases.  相似文献

Hyperadrenocorticism is a rare syndrome in cats. Current medical therapy is unsatisfactory and prognosis for long-term survival with surgical treatment is guarded. We report on 5 cats treated with the 3-beta hydroxysteroid dehydrogenase inhibitor trilostane. Diagnosis was confirmed in all cats by endocrine testing. Three cats had concurrent diabetes mellitus. Trilostane reduced clinical signs and improved endocrine test results in all cats, but insulin requirements did not change and all continued to have some signs of hypercortisolemia. Two died or were euthanized after 16 and 140 days, whereas 3 were still alive 6, 11, and 20 months after the start of trilostane therapy. Trilostane ameliorates clinical signs of feline hyperadrenocorticism, but more research is needed before it can be recommended for treatment.  相似文献

Objective – To determine the safety and efficacy of high‐dose fomepizole compared with ethanol (EtOH) in cats with ethylene glycol (EG) toxicosis. Design – Prospective study. Setting – University veterinary research laboratory. Animals – Thirteen cats. Interventions – Two cats received injections of high‐dose fomepizole (Study 1). Three cats received lethal doses of EG and fomepizole treatment was initiated 1, 2, or 3 hours later (Study 2). Eight cats received a lethal dose of EG and were treated with fomepizole or EtOH (Study 3). Cats treated with fomepizole received 125 mg/kg IV initially, then 31.25 mg/kg at 12, 24, and 36 hours. Cats treated with EtOH received 5 mL of 20% EtOH/kg IV initially, then every 6 hours for 5 treatments, then every 8 hours for 4 treatments. Cats also received fluids and supportive therapy as needed. Measurements and Main Results – Clinical signs were monitored and serial blood analyses performed. Cats receiving fomepizole experienced mild sedation but no biochemical evidence of toxicity. Cats receiving fomepizole for EG intoxication survived if therapy was initiated within 3 hours of EG ingestion. One of the 6 developed acute renal failure (ARF) but survived. Only 1 of the 3 cats treated with EtOH 3 hours following EG ingestion survived; 2 developed ARF and were euthanized. Cats treated 4 hours following EG ingestion developed ARF, whether treated with EtOH or fomepizole. Conclusions – Fomepizole is safe when administered to cats in high doses, prevents EG‐induced fatal ARF when therapy is instituted within 3 hours of EG ingestion, and is more effective than treatment with EtOH.  相似文献

Hyperthyroidism was diagnosed in 4 cats with congestive heart failure. Dyspnea and anorexia were observed in 3 of the 4 cats. In each cat, a holosystolic left and/or right apical heart murmur was auscultated. In 3 cats, a prominent extra heart sound (gallop rhythm) was auscultated. All cats had a palpably large thyroid lobe(s) and weight loss. The laboratory and ECG changes were similar to those reported for feline hyperthyroidism. Moderate-to-severe pleural effusion and cardiomegaly were detected via radiography in all cats. Some cats had radiographic signs of pulmonary venous engorgement and pulmonary edema. Echocardiography revealed cardiac dilatation and low left ventricular shortening fraction (wall motion) in all cats. Three cats responded initially to cardiac drugs and propylthiouracil or thyroidectomy. One of these died later, presumably from an adverse reaction to propylthiouracil, and the others died from recurrent congestive heart failure (1) or postoperative cardiac arrest (1). One cat did not respond to treatment, and died 2 days after diagnosis.  相似文献

OBJECTIVE: To characterize rib, intrathoracic, and concurrent orthopedic injuries, and prognosis associated with traumatic rib fracture in cats. DESIGN: Retrospective study. ANIMALS: 75 cats. PROCEDURE: Medical records from January 1980 to August 1998 were examined for cats with traumatic rib fracture. Signalment, cause of trauma, interval from trauma to evaluation at a veterinary teaching hospital, referral status and date, method of diagnosis, duration of hospitalization, number and location of rib fractures, presence of flail chest, costal cartilage involvement, intrathoracic and concurrent orthopedic injury, and clinical outcome were reviewed. RESULTS: Median age was 3 years. Twenty-five (58%) cats with reported cause of trauma were injured by interaction with another animal. Forty-seven (78%) cats that were treated survived. Cats that died had a median duration of hospitalization of < 1 day. Ten (13%) cats had flail chest. Sixty-five (87%) cats had intrathoracic injury (median, 2 injuries). Nine (100%) cats without detected intrathoracic injury that were treated survived. Thirty-five (47%) cats had concurrent orthopedic injury. Cats with flail chest, pleural effusion, or diaphragmatic hernia were significantly more likely to die than cats without each injury. CONCLUSIONS AND CLINICAL RELEVANCE: Traumatic rib fracture in cats is associated with intrathoracic and concurrent orthopedic injury. Aggressive treatment of cats with traumatic rib fracture is warranted, because the prognosis is generally favorable. Diagnosis and treatment of intrathoracic injury associated with traumatic rib fracture in cats should precede management of concurrent orthopedic injury.  相似文献

Objective—To describe the effect of hypothermic storage on transplanted feline kidneys.
Study Design—Kidneys were stored in University of Wisconsin (UW) sodium gluconate (n = 3) or phosphate-buffered sucrose (n = 5) solutions before transplantation.
Animal Population—Eight cats with renal failure and seven normal cats as kidney donors.
Methods—Kidneys were perfused through the renal artery with cold (10°C) storage solution and immersed in the solution on ice until transplantation.
Results—Mean ex vivo storage time was 4.8 ± 0.36 hours (range, 3.5 to 7 hours). Seven recipient cats survived surgery. Five of the cats had decreased serum creatinine concentrations from a mean of 8.2 mg/dL (range, 4.0 to 15.8 mg/dL) preoperatively to 1.7 mg/dL (range, 1.3 to 2.2 mg/dL) within 4 days of surgery. In one cat, serum creatinine concentration dropped from 15.1 to 3.7 mg/dL in 3 days, but the cat developed a ureteral stricture that required revision. One graft did not function, and the cat died on day 19. The mean postoperative survival time of cats that were discharged from the hospital (n = 6) was 254 days (range, 49 to 717 days) at the time of this report. Long-term renal function (>60 days postoperatively; n = 5) was excellent with mean serum creatinine concentrations of 1.6 ± 0.15 mg/dL.
Conclusions—Hypothermic storage is feasible for short-term preservation of feline kidneys.
The maximal length of feasible storage remains unknown.
Clinical Relevance—Hypothermia protects against ischemia-induced nephron loss during ex vivo manipulation of the allograft and allows longer safe vascular anastomosis times. Short-term hypothermic storage also provides time to accommodate modifications in scheduling or anesthetic management of the recipient operation.  相似文献
