This paper summarises the clinical findings of 12 cases of splenic abscessation in horses presented to Texas A&M University Veterinary Medical Teaching Hospital from 1993 to 2015. The objective of this study was to describe the signalment, clinical and laboratory findings, diagnostics, treatment and outcome of horses affected with splenic abscessation. Only horses in which a splenic abscess was confirmed by microbiological or cytological confirmation from a percutaneous, surgical, or necropsy sample were included in this study. No apparent breed or sex predilection was identified. The mean age of presentation was 9 years, with a range of 1–21 years of age. The most common presenting clinical signs were nonspecific signs including fever, anorexia and lethargy. A variety of bacterial organisms were identified and treatment with antimicrobial agents or surgical exploration was attempted in several of the cases. None of the cases survived to discharge from the hospital. 相似文献

Objective-To evaluate whether dogs undergoing splenectomy had an increased risk of gastric dilatation-volvulus (GDV), compared with a control group of dogs undergoing enterotomy. Design-Retrospective case-control study. Animals-219 dogs that underwent splenectomy for reasons other than splenic torsion (splenectomy group; n = 172) or enterotomy (control group; 47) without concurrent gastropexy. Procedures-Medical records were reviewed for information on signalment, date of surgery, durations of surgery and anesthesia, reason for splenectomy, histopathologic findings (if applicable), whether gastropexy was performed, duration of follow-up, and date of death (if applicable). Follow-up information, including occurrence of GDV, was obtained via medical records review and a written client questionnaire. Results-Reasons for splenectomy included splenic neoplasia, nonneoplastic masses, infarction, traumatic injury, and adhesions to a gossypiboma. Incidence of GDV following surgery was not significantly different between dogs of the splenectomy (14/172 [8.1 %]) and control (3/47 [6.4%]) groups. Median time to GDV for the 17 affected dogs was 352 days (range, 12 to 2,368 days) after surgery. Among dogs that underwent splenectomy, sexually intact males had a significantly higher incidence of GDV (4/16) than did castrated males and sexually intact or spayed females (10/156). Incidence of GDV among sexually intact male dogs did not differ between groups. Conclusions and Clinical Relevance-Results did not support a recommendation for routine use of prophylactic gastropexy in dogs at the time of splenectomy. Other patient-specific risk factors should be assessed prior to recommending this procedure. 相似文献

Brain abscesses and intracranial masses have been regularly described in horses. Treatment often is difficult and unrewarding and mortality rate high. This case report describes the successful treatment of a cerebral abscess in a 2-month-old female Warmblood foal with severe neurological signs of acute onset. Computed tomography (CT) revealed a 3 × 4 × 4 cm cerebral mass in the left brain hemisphere with severe cerebral oedema. Craniotomy, using a parietal bone flap technique, allowed the abscess to be sampled, drained and lavaged. Immediately, post-surgery the foal showed significant clinical improvement. Sample culture confirmed Streptococcus equi equi infection. The foal was medically treated for 6 weeks, leading to complete clinical and radiographical recovery. Intracranial surgery in equine medicine is limited. Using a parietal bone flap instead of partial craniectomy to gain access to the cerebrum is a less invasive procedure leading to a better aesthetic result and should be considered for the treatment of cerebral masses in the horse. 相似文献

A 4-year-old intact female American Pit Bull Terrier from Italy descendant of an American-born bitch was evaluated for anorexia, lethargy, weakness, and intermittent vomiting. On physical examination, the dog was dehydrated, had pale mucous membranes, hunched posture and abdominal pain. A moderate anemia was observed. Splenomegaly and hyperechoic regions suspected as infarcts in the spleen were seen on abdominal ultrasound. Based on the suspicion of splenic torsion, splenectomy was performed. After surgery, the clinical condition deteriorated. A follow-up complete blood count demonstrated severe macrocytic normochromic anemia with evidence of marked regeneration, left shift neutrophilia, monocytosis and marked thrombocytopenia. Blood smear evaluation revealed single to multiple, variable sized (1–3 μm in diameter), and round to oval to band-like piroplasms within many red blood cells consistent with small form Babesia spp. or Theileria spp. A partial segment of the 18S rRNA gene was amplified and the PCR product was analyzed by direct sequencing. The nucleotide sequence was completely identical to that of Babesia gibsoni present in GenBank®. This is the first molecular detection and characterization of B. gibsoni infection in a sick dog from Italy. 相似文献

A 9-year-old cob mare with a history of recurrent colic presented during an acute colic episode. Ultrasonography revealed a mass emanating from the greater curvature of the stomach and was tightly adhered to the cranial edge of the spleen. Partial gastrectomy and total splenectomy were performed via a midline celiotomy incision. The mass was subsequently confirmed to be granulomatous inflammation, postulated to be secondary to a penetrating injury to the stomach. Post-operatively, the mare had episodes of recurrent colic that were successfully managed with optimisation of the horse's diet and feeding regime. At 10 months’ post-operatively the mare was managed on full turn out, with no evidence of colic and had returned to the previous level of ridden work. The horse then presented 14 months post-operatively with severe colic due to a large colon impaction and displacement and was euthanased. This is the first report to describe successful partial gastrectomy as a treatment option for a gastric mass in the horse. 相似文献

Timely delivery of adjuvant chemotherapy has been shown to be advantageous in many human cancers and canine osteosarcoma. Adjuvant chemotherapy has been shown to improve outcome for canine splenic hemangiosarcoma. The aim of this retrospective study was to investigate whether timely adjuvant chemotherapy administration resulted in better outcome in dogs with non-metastatic splenic hemangiosarcoma undergoing splenectomy. Medical records were searched for dogs with non-metastatic, splenic hemangiosarcoma that received splenectomy and adjuvant chemotherapy. The number of days from surgery to the first chemotherapy dose (StoC) was evaluated to identify the cut-off value associated with the best survival advantage. StoC and other possible prognostic factors were tested for influence on time to metastasis (TTM) and overall survival (OS). Seventy dogs were included. Median StoC was 20 days (range: 4–70). The time interval associated with the greatest survival benefit was 21 days. Median TTM and OS of dogs with StoC ≤ 21 days were significantly longer than those with StoC >21 days (TTM: 163 vs. 118 days, p = .001; OS: 238 vs. 146 days, p < .001). On multivariable analysis, StoC >21 days was the only variable significantly associated with increased risk of tumour progression (HR 2.1, p = .010) and death (HR 2.3; p = .008). Starting adjuvant chemotherapy within 21 days of surgery may be associated with a survival benefit in dogs with non-metastatic splenic hemangiosarcoma, possibly due to the early targeting of newly recruited metastatic cells after surgery. 相似文献

A 10-year-old castrated male Standard Poodle presented with an acute onset of lethargy and abdominal pain. The animal had a history of traumatic splenic rupture requiring splenectomy 5 years previously. Surgical exploration revealed multiple cystic red nodules involving all liver lobes, several of which were submitted for histopathology. Microscopically, the cystic nodules were dilated bile ducts and lymphatics surrounded by ectopic splenic tissue. A diagnosis of intrahepatic splenosis was made. 相似文献

OBJECTIVE:To evaluate the safety and efficacy of an ultrasonically activated scalpel for performing splenectomy, with minimal ligation, in dogs. STUDY DESIGN: Prospective clinical study. ANIMALS: Dogs (10) with naturally occurring splenic disease. METHODS: Between October 2003 and February 2004, splenectomy was performed using an ultrasonically activated scalpel and a double seal method, in 10 dogs with naturally occurring splenic disease. Time for splenectomy and number of ligatures required were recorded. Intraoperative hemostasis, device ease of use, postoperative hemorrhage, and short-term survival were evaluated. RESULTS: Mean operative time for splenectomy, exclusive of celiotomy and closure, was 18 minutes (range, 8-25 minutes). The mean number of ligatures needed to perform splenectomy was 1 (range, 0-2 ligatures). One dog hemorrhaged from the splenic vein after ultrasonic scalpel transection of a vessel >5-mm diameter and required a ligature. The ultrasonic scalpel was easy to use, with a minimal learning curve. None of the dogs had postoperative abdominal hemorrhage; 9 dogs were discharged and 1 dog was euthanatized because of septicemia. CONCLUSION: Ultrasonic activated scalpel may be used to achieve efficient and safe hemostasis of the splenic vascular pedicle in dogs with minimal need for vascular ligation. CLINICAL RELEVANCE: Ultrasonic scalpels can be used to perform splenectomy in dogs with naturally occurring splenic disease. 相似文献

A preputial foreign body caused severe preputial swelling and depression in a 4-year-old Shorthorn bull. Disruption of the preputial epithelium by the foreign body resulted in abscess formation lateral to the prepuce. A patent urethral fistula, probably a complication of prior fibropapilloma excisional surgery, was also detected on the distal portion of the glans penis. Foreign body removal, antimicrobial administration, and warm hydrotherapy resolved the swelling and abscess. Electroejaculation was used to extend the penis and to minimize preputial adhesions. Breeding soundness examinations were used to evaluate breeding potential. 相似文献

A 2-month-old Thoroughbred filly was referred to Hagyard Equine Medical Institute for further evaluation of acute pyrexia and a suspected intra-abdominal abscess based on abdominal ultrasonography performed in the field. Initial examination revealed bilateral uveitis, polysynovitis, a large internal abdominal abscess and pneumonia. A transtracheal wash confirmed the presence of a multi-sensitive strain of Rhodococcus equi. Anaemia and thrombocytopenia were noted during hospitalisation. Results of a Coombs test were consistent with an immune-mediated haemolytic process. Recurrent pyrexia, abdominal discomfort and severe respiratory distress unresponsive to intensive medical support motivated euthanasia followed by necropsy after 30 days of treatment. Overall, six extra-pulmonary disorders were simultaneously diagnosed despite the lack of pulmonary pyogranulomas. 相似文献

A 4-year-old female spayed domestic ferret (Mustela putorius furo) presented with a history of vomiting over 24 hours. On physical examination, a significantly enlarged, firm spleen was palpated. Abdominal radiographs and abdominal ultrasound were suggestive of a splenic torsion or splenic infarction. An exploratory laparotomy confirmed the initial diagnosis and splenectomy was performed using a vessel sealing device. Histologic evaluation and culture of the spleen were consistent with primary torsion without evidence of infection or neoplasia. The patient recovered from surgery without complications. Based on a literature search, this is the first report of the clinical diagnosis and successful surgical treatment of a primary splenic torsion in a ferret. Although it appears to be a rare and potentially life-threatening disease in ferrets, splenic torsion should be considered as a differential diagnosis in ferrets that present with non-specific signs and a palpably enlarged spleen. 相似文献

Sixteen dogs with splenic infarction due to causes other than splenic torsion were identified. Dogs with splenic infarction often had multiple concurrent diseases, and surgical management of splenic infarction was associated with high mortality. Splenic infarction occurred in dogs with hypercoagulable conditions associated with liver disease, renal disease, and hyperadrenocorticism, or as a consequence of uniform splenomegaly, neoplasia, or thrombosis associated with cardiovascular disease. Clinical signs and common laboratory findings generally reflected the underlying disease process. A variety of splenic abnormalities were detected by abdominal ultrasound in 15 dogs, with the ventral extremity of the spleen being most often abnormal. Four dogs were euthanized or died because of the presence of severe systemic disease, whereas 12 dogs underwent laparotomy. Complete splenectomy was performed in 9 dogs and partial splenectomy was performed in 2 dogs. Seven dogs died in the immediate postoperative period, 3 required chronic veterinary care, and 2 had uncomplicated long-term recoveries. Splenic infarction should be regarded as a sign of altered blood flow and coagulation, rather than as a primary disease, and surgical management should be reserved for patients with life-threatening complications such as hemoabdomen or sepsis. 相似文献

Objective: To (1) describe a technique for splenic vessel hemostasis and (2) report complications and outcome after use of bipolar sealant device during splenectomy in dogs. Study Design: Case series. Animals: Dogs (n=27) with naturally occurring splenic disease. Methods: Between January 2006 and March 2008, splenectomy was performed using a vessel sealant device in 27 dogs with naturally occurring splenic disease. Number of sutures needed for splenectomy and complications were recorded. Splenic artery diameter was measured using a caliper. Intraoperative hemostasis, device ease of use, postoperative hemorrhage, and short‐term survival were evaluated. Results: Splenectomy was performed successfully in 27 dogs with the vessel sealant device; none of the dogs required vessel ligation with suture. The splenic artery was dissected and adequately sealed in each dog. One dog was readmitted 4 days after surgery with hemoabdomen. Abdominal exploration revealed splenic pedicle hemorrhage and pancreatitis, the vessel sealant device was used to coagulate splenic pedicle bleeding. The dog was alive at suture removal. Conclusion: In dogs, a vessel sealant device may be used to achieve efficient and safe hemostasis of the splenic vascular pedicle without sutures. 相似文献

We previously described successful treatment, including surgical drainage, of a Streptococcus equi subspecies equi brain abscess that caused severe neurological deficits in a 7-year-old Quarter Horse mare. This report details the long-term successful outcome of the case, findings of a magnetic resonance imaging (MRI) study performed 14 years after surgery and necropsy findings 18 years after initial treatment. Despite persistent cerebral and midbrain lesions detected by MRI and at necropsy, the mare returned to serviceable function within a year of initial treatment and had a successful performance career for over 10 years until carpal arthritis prompted retirement. This case demonstrates that brain abscess in horses can be successfully managed by combined medical and surgical treatment. 相似文献

A 9-yr-old female Bornean orangutan (Pongo pygmaeus pygmaeus) presented with a 48-hr history of depression, lethargy, anorexia, and mucoid discharge from the rectum. Clinical, radiographic, and ultrasonographic examination demonstrated the presence of multiple distended loops of intestine, intestinal adhesions, and free gas within the abdomen. During exploratory laparotomy, fibrinopurulent diffuse peritonitis as a result of a ruptured intrapelvic abscess with associated large bowel adhesions was evident. The abdomen was thoroughly lavaged, necrotic debris and abscess wall removed, and fibrinous adhesions disrupted. The orangutan was kept sedated for 48 hr to allow for intensive care. Six months later, when the orangutan presented with similar clinical signs, ultrasonographic examination demonstrated the presence of a pelvic abscess. The previous procedure was repeated with the addition of a hysterectomy. This report is the first documentation of long-term management following surgical intervention for internal abdominal abscessation and septic peritonitis in a great ape. 相似文献

A 13‐year‐old spayed female Pomeranian dog was presented for persistent, severe hypoglycemia (37 mg/dL; reference interval [RI] 75‐128 mg/dL). Progressive nonregenerative anemia (hematocrit 23.3%‐15.9%; RI 37.0%‐55.0%) and severe thrombocytopenia (36 000/µL; RI 200‐500 000/µL) were also noted. The serum insulin concentration was low (0.24 ng/mL; RI 0.302‐1.277 ng/mL). Computed tomography revealed multiple splenic nodules (1‐6 mm in diameter) and several hepatic nodules (7.6, 12 mm in diameter). Ultrasound‐guided fine‐needle aspiration of the splenic and hepatic nodules revealed low numbers of epithelial cells with mild cellular atypia, suggestive of a metastatic epithelial tumor, but the primary site was unknown at that time. On careful oral examination under general anesthesia, an enlarged right tonsil was noted grossly, and histopathologic examination of the tonsil diagnosed squamous cell carcinoma. Bone marrow aspirates and biopsies of the splenic and hepatic nodules were performed; all samples were diagnosed as metastatic carcinoma on histopathologic examination. No nodules were present in the pancreas, despite careful palpation during exploratory laparotomy. On immunohistochemistry, the neoplastic cells were positive for cytokeratin AE1/3 and insulin‐like growth factor (IGF)‐I but were negative for chromogranin A, PGP9.5, insulin, and inconclusive for IGF‐II. This is the first report of a primary IGF‐I‐producing squamous cell carcinoma in the tonsil of a dog with metastases to bone marrow, liver, and spleen, resulting in hypoglycemia. 相似文献

Treatment options for dogs with metastatic (stage III) splenic hemangiosarcoma are limited. A doxorubicin‐based chemotherapy regimen is commonly administered; however, there are no published data to support this practice. The aim of this study was to investigate the impact of maximum‐tolerated‐dose chemotherapy (MTD), metronomic chemotherapy (MC) and no adjuvant treatment on outcome in dogs with stage III splenic hemangiosarcoma undergoing splenectomy. Medical records of dogs with stage III splenic hemangiosarcoma that underwent splenectomy followed by MTD chemotherapy, MC or no adjuvant treatment were retrieved. Time to progression (TTP), survival time (ST) and toxicity were evaluated. One hundred three dogs were identified: 23 received adjuvant MTD, 38 MC and 42 were not medically treated. Overall median TTP and ST were 50 (95% confidence interval [CI], 39‐61) and 55 days (95% CI, 43‐66), respectively. Dogs treated with adjuvant MTD had a significantly longer TTP and ST compared with dogs receiving MC (median TTP, 134 vs 52 days, P = .025; median ST, 140 vs 58 days, P = .023, respectively). Dogs treated by splenectomy only had the shortest median TTP (28 days) and ST (40 days). However, treatment‐related adverse events (AEs) were significantly more frequent in the MTD group (P = .017). The outcome for dogs with metastatic splenic hemangiosarcoma is poor. While MTD showed greater efficacy compared to MC, toxicity was higher in this group. Treatment‐related AEs need to be carefully balanced against this modest survival prolongation when offering adjuvant MTD to dogs with advanced stage hemangiosarcoma. 相似文献

A 6-year-old male Rhodesian Ridgeback dog developed splenosis following splenectomy for a rupture of the spleen. The dog did well for 4 years following splenectomy but then developed progressive hepatomegaly, leading to the death of the animal. Grossly the abdomen was filled with masses of tissue arising from the liver. Multiple nodules of various sizes were seen in the remainder of the liver and attached to the mesentery, diaphragm and peritoneal wall. Histologically, the lesions contained splenic tissue consisting of both red and white pulp, and were characterized by all the normal cell elements of the spleen, including erythropoietic tissue. The proportion of red to white pulp was, however, abnormal, and the fibromuscular septae and sheath arteries were not obvious. In the smaller lesions, and in the margins of the large lesions, splenic tissue replaced the hepatic tissue except for the bile ducts. The multiple, intrahepatic nodules indicated splenic vein embolism. 相似文献

Objective: To report laparoscopic splenectomy in a dog. Study Design: Clinical report. Animals: Mixed breed dog (n=1). Methods: Hemangiosarcoma was diagnosed by ultrasound‐guided fine‐needle aspiration of a splenic mass in an 11‐year‐old, 30 kg, mixed breed dog. No metastatic disease was identified during complete staging (chest radiographs, echocardiogram, and abdominal ultrasonography); however, cystic calculi were identified. Laparoscopic splenectomy using Ligasure V was performed through 3 portals and the calculi were removed by laparoscopic‐assisted cystoscopy. Results: Total surgical time was 2 hours and for laparoscopic splenectomy, 65 minutes. The celiotomy incision for splenic removal was 7 cm. The dog recovered uneventfully and was ambulatory 2 hours postoperatively. Conclusion: Laparoscopy with Ligasure V facilitated successful removal of a spleen with a 3 cm mass. Clinical Relevance: Laparoscopic splenectomy in dogs is feasible for removal of a normal‐sized spleen with a moderate‐sized mass. 相似文献
