A 2-year-old, male castrated ferret (Mustela putorius furo) was presented with progressive abdominal distention and loss of muscle mass despite normal appetite. Physical examination findings included pale mucous membranes, a prolonged capillary refill time, a pulse rate greater than 300 beats/min, and severe abdominal distention. Abdominal ultrasound showed free abdominal fluid and an enlarged liver with distended hepatic veins and caudal vena cava. During the echocardiographic examination, abnormalities observed included a 2-mm-diameter left-to-right shunting atrial septal defect (ASD) with concurrent severe dilatation of the right atrium and eccentric hypertrophy of the right ventricle with mild pulmonary hypertension. All other echocardiographic measurements were within normal limits. The owner declined treatment, and the ferret was euthanized. Postmortem examination confirmed the ultrasonographic findings. The free abdominal fluid (200 mL) was a non-septic fibropurulent exudate. Decompensated right-sided heart failure due to ASD and exudative peritonitis of undetermined origin were the final diagnoses. To our knowledge, this is the first report of an ASD in a ferret.  相似文献

A 7.5-year-old castrated male ferret (Mustela putorius furo) was diagnosed with third-degree atrioventricular (AV) block. A monopolar epicardial pacemaker system was implanted, resulting in a regular, paced cardiac rhythm with third-degree AV block at 140 beats per minute. Over the next 2 months, the ferret developed anorexia, interstitial pneumonia, intermittent diarrhea, and hind-limb weakness and had a slow and progressive recovery. The ferret developed clinical signs of congestive heart failure 4 months after the surgery, resulting in its death 3 weeks later. Necropsy results attributed the death to cardiac failure due to extensive myocardial mineralization. To the authors' knowledge this is the first published report of surgical report of surgical pacemaker implantation in a ferret.  相似文献

A four-year-old, castrated male ferret (Mustela putorius furo) was evaluated because of a one-year history of sporadic cough. On physical examination a grade 5 of 6 holosystolic murmur was audible over the right apex of the heart. Radiographic findings included the presence of air bronchograms in apical lobes accompanied by pulmonary venous congestion. Colour Doppler echocardiography revealed a left-to-right shunting compatible with a ventricular septal defect. Medical therapy was initiated at the time of the diagnosis. The ferret was presented again 2 months after the initial examination for coughing and respiratory distress. Echocardiographic findings included tricuspid regurgitation, relative enlargement of left-atrial diameter and decreased systolic function, with presence of pleural effusion. Thoracocentesis was performed and the therapeutic plan was revised. In the following months the symptoms did not recur. In the authors' opinion this is the first report to describe the clinical findings of isolated ventricular septal defect in the ferret. Congenital heart defects are rare in this species, the present ferret being only the second case described.  相似文献

A 6-month-old German shepherd dog was referred for evaluation of a cardiac murmur.Upon physical examination, the auscultated heart rate was 120 beats/min, and a grade IV/VI systolic heart murmur with a point of maximal intensity over the left heart base radiating up the neck was heard. The standard echocardiographic examination showed subaortic stenosis and an anechoic tubular structure extending from the sinus of Valsalva to the left ventricular posterior wall. Aneurysmal left coronary artery (CA) was confirmed by angiography. The dog was euthanized and post-mortem examination showed severe dilatation of the proximal left CA and confirmed the subaortic stenosis. Histopathology did not demonstrate abnormalities in the walls of the CA, aorta or pulmonary artery.The exact cause of the CA aneurysmal dilation remains unknown. Subaortic stenosis, elevated coronary vascular resistance or a congenital anomaly may have contributed to the dilation.To our knowledge, coronary aneurysmal dilation has never been described in dogs. Standard echocardiography provides reliable information on coronary anatomy.  相似文献

A five-month-old, intact female Domestic Shorthair cat presented to the Kansas State Veterinary Health Center for evaluation of a murmur and exercise intolerance. Physical exam revealed a grade V/VI right, parasternal, holosystolic murmur. On echocardiogram, there was an abnormality in the membranous interventricular septum and tricuspid valve, allowing blood to shunt from the left ventricle to the right atrium. This lesion is consistent with an infravalvular Gerbode defect. The Gerbode defect is a rare, left ventricle-to-right atrial shunt that can be congenital or acquired, and in cats, has only been reported once. At the time of submission, the patient is alive and is maintaining a good quality of life.  相似文献

A 4-yr-old male ferret (Mustela putorius furo) was presented with a 3-day history of pelvic limb ataxia and weakness. A cellulitis associated with a deep bite wound was identified and initially treated with antibiotics and anti-inflammatory medication. Two weeks later, a grade IV/VI cardiac murmur was identified on physical examination. Echocardiographic examination revealed irregular thickening of the aortic valve leaflets, with normal chamber dimensions and normal systolic function. The ferret's physical condition rapidly deteriorated and it was subsequently euthanatized. Myxomatous degeneration of the aortic valve leaflets, with ulceration and vegetative lesions, and multiorgan infarctions were identified during necropsy. A bacterial etiologic agent was not identified from blood culture or histopathology. Lesions present were consistent with nonbacterial thrombotic endocarditis, a novel condition in the ferret.  相似文献

A castrated adult male 1.0-kg domestic ferret (Mustela putorius furo) was referred for evaluation of a mass of >5 mo duration that was associated with the thoracic spine. The ferret had motor dysfunction and no conscious proprioception or pain perception in either hind limb. Segmental reflexes were present. Survey radiography, myelography, and magnetic resonance imaging showed a mass involving the ninth and 10 thoracic vertebrae and compressing the spinal cord. Decompressive surgery was performed, but clinical signs persisted. A diagnosis of chordoma was made using histopathology and immunohistochemistry. This is the first reported case of a chordoma involving the thoracic vertebrae in a domestic ferret.  相似文献

The objective of this prospective study was to determine the prevalence of echocardiographic evidence of heart disease in apparently healthy cats with heart murmurs. Thirty-two privately owned domestic cats were examined. All cats were considered healthy on the basis of history and physical examination, except for the finding of a heart murmur on auscultation. Cats on any medications (besides regular flea, tick and heartworm preventative) or that were pregnant or lactating were excluded from this study. The prevalence of echocardiographic evidence of heart disease in this population of cats was 53%. Therefore, identification of a heart murmur on routine physical examination in apparently healthy cats warrants further investigation.  相似文献

A 5-year-old male castrated ferret was presented to the Washington State University College of Veterinary Medicine for evaluation of progressive hair loss and a large, rapidly growing ventral neck mass. The patient had been diagnosed previously with an insulinoma, which was managed medically. Fine-needle aspirates of the neck mass were performed. The cytologic results were most consistent with epithelial neoplasia, likely a carcinoma; thyroid origin was considered likely based on tumor location and cell morphology. The tumor grew rapidly, and the owners elected euthanasia 1 week after examination. At necropsy, a circumscribed, ovoid mass disrupted the right cervical musculature next to the right lobe of the thyroid gland. Histopathologic evaluation revealed an infiltrative mass consisting of cuboidal cells arranged in solid sheets and irregular follicles enclosing colloid. The cells were large, with prominent nucleoli, and had a high mitotic rate. The histopathologic diagnosis was consistent with thyroid follicular adenocarcinoma. Immunochemical findings confirmed thyroglobulin production by neoplastic cells, but to a lesser extent than in normal ferret thyroid tissue. To our knowledge, this is the first case of thyroid follicular adenocarcinoma to be reported in a ferret, with only 1 other case of thyroid carcinoma, a C-cell carcinoma, described previously.  相似文献

Heart murmurs are caused by turbulent blood flow or by vibration of cardiac structures. Turbulent blood flow may originate from structural heart disease or from physiological phenomena. The aims of this study were to establish the cause of heart murmurs in apparently healthy adult cats and to determine whether a heart murmur is a reliable indicator of heart disease. In this retrospective study, we reviewed the medical records of cats in which a heart murmur was detected during physical examination by one of the authors in the period January 2008 to December 2009. Cats younger than 6 months and those with systemic disease were excluded. Timing, grade, and point of maximum intensity of the murmur were determined by one observer (MD) before 2D-, M-mode and Doppler echocardiography. Fifty-seven cats (median age 76 months, range 6-194) were included, 30 neutered females and 27 neutered males. All murmurs were systolic and varied in intensity from 2/6 to 5/6. The point of maximum intensity was the left or right parasternal region in 34/57 (61%) of murmurs. Murmurs were caused by dynamic left ventricular outflow tract obstruction in 25/57 (44%) cats, dynamic right ventricular outflow tract obstruction in 9/57 (16%) cats, and combined dynamic left and right outflow tract obstruction in 11/57 (19%) cats. In 5 (9%) cats the cause of the murmur could not be identified. Heart disease was present in 50 (88%) cats, namely, left ventricular hypertrophy in 44 (77%) and congenital defects in 6 (11%) cats. In conclusion, most heart murmurs in apparently healthy cats are detected in the left or right parasternal region and are caused by dynamic left and right ventricular outflow tract obstruction. Because most cats (88%) with a heart murmur had heart disease in this study, if a heart murmur is detected in an apparently healthy cat, echocardiography is recommended to determine the cause of the heart murmur and the presence of heart disease.  相似文献

A 5-year old, neutered, male, domestic sable ferret presented 24 hours after escaping outside and sustaining unknown trauma. Physical examination findings included tachycardia, tachypnea, and hind limb paresis in a laterally recumbent patient. Radiographs, laboratory evaluation, and abdominocentesis revealed the presence of hemoperitoneum, blunt hepatic trauma, pneumothorax, and a small abdominal hernia. The ferret was treated with resuscitative fluids, thoracocentesis, abdominal counterpressure, and blood transfusion. This is the first case report of multi-systemic trauma in a ferret. The ferret made a complete recovery and was discharged to the referring veterinarian three days after presentation. (Vet. Emerg. Crit. Care, 10:13–18, 2000)  相似文献

A 1-year-old intact male Boxer was presented to the Texas Veterinary Medical Center for emergency treatment following suspected ingestion of a large number of tablets of Adderall, a pharmaceutical amphetamine. The dog had a temperature of 41.7 degrees C, heart rate of 192 beats per minute, and a respiratory rate of 100 breaths per minute. The dog was anxious and agitated with bilaterally dilated pupils, and shortly thereafter became recumbent and incontinent. Initial CBC results included mild leukopenia and mild thrombocytopenia. The dog was not anemic (HCT 39.9%) and had only slight polychromasia, but had 48 nucleated RBCs/100 WBC (7500/microL). Moderate numbers of neutrophils had hypersegmented nuclei and several pyknotic cells were noted. The metarubricytosis persisted for approximately 56 hours while hypersegmentation and pyknotic cells were no longer found at 8 hours after presentation. The dog received supportive care and recovered uneventfully. We hypothesized that hyperpyrexia associated with Adderall toxicity resulted in inappropriate metarubricytosis due to damaged bone marrow endothelium, and resulted in hypersegmentation and pyknosis due to damaged or accelerated aging of neutrophils in peripheral blood. Metarubricytosis has been reported previously in dogs with heat-induced illness, such as heat stroke.  相似文献

A 16-month-old, neutered female domestic shorthaired cat had tachypnoea, inappetence and a heart murmur, which had been first detected at eight weeks old. Diagnosis of reverse shunting patent ductus arteriosus and pulmonary hypertension was based on a detailed two-dimensional and Doppler echocardiographic examination. This report documents the clinical and imaging findings in this rare feline condition.  相似文献

A 5-year-old male neutered ferret (Mustela putorius) and a 2-year-old male neutered ferret were evaluated for fast growing immobile swellings involving the left hock and the right scapula, respectively. In both cases, serum chemistry was unremarkable and a complete blood count demonstrated mild anemia. In case 1, radiographic evaluation demonstrated increased soft tissue density in the region of the distal tibia and fibular tarsal bone. A fine-needle aspirate demonstrated atypical mesenchymal cells, and an incisional biopsy revealed irregular partly mineralized proliferations of cartilage consistent with chondrosarcoma. Computed tomography was performed, demonstrating attachment of the mass to the distolateral tibial epiphysis. A limb-sparing surgery was performed; however, 5 months following resection local reoccurrence was noted. At 18 months, the ferret underwent a left hind limb amputation. No sign of metastatic disease was reported at 27 months. In case 2, radiographic evaluation demonstrated a poorly organized mineralized soft tissue mass extending from the right acromion to the area surrounding the neck of the scapula. Microscopic evaluation of an incisional biopsy revealed a chondrosarcoma. A forequarter amputation was performed. The ferret died 4 years later with no evidence of local recurrence or the development of metastatic disease. These 2 cases represent the first reports of chondrosarcoma in the appendicular skeleton of 2 ferrets. Based on these 2 cases, local recurrence may be expected unless adequate surgical margins are achieved. The metastatic potential of chondrosarcoma in this species appears to be low.  相似文献

A domestic ferret was presented for episodic regurgitation. Cytologic examination and culture of an enlarged submandibular lymph node revealed Cryptococcus neoformans variety grubii (serotype A). The ferret was successfully treated with itraconazole. This is the first documented case of Cryptococcus neoformans variety grubii in a ferret in the United States.  相似文献

Cloned pregnancies in cattle are considered to be at risk due to a variety of fetal or adnexal abnormalities. Data is lacking concerning the possibility of transabdominal ultrasonography in the assessment of these high risk pregnancies. Transabdominal ultrasonography has rarely been reported in the assessment of bovine cloned pregnancies. Ten Holstein heifers carrying 8-month-old cloned fetuses were assessed by transabdominal ultrasonographic examination during the 3rd trimester of pregnancy. Fetal heart rates (FHR), movements, adnexal appearance, and placentome size were recorded. The outcome of the pregnancies was also noted and potential indicators of fetal demise recorded. Survival rate 1 week after birth was 30%. Mean FHR was 113 beats per minute (range: 92 to 128 bpm) during the fetal ultrasonography. No correlation between FHR and fetal activity was found. Fetal hyperactivity and imaging of hyperechoic particles in both allantoic and amniotic fluids were possible signs of fetal distress. Despite the size of the fetus and the deep bovine abdomen, fetal transabdominal ultrasonography can be performed in cattle. This preliminary study points to the necessity of further larger studies for defining normal and abnormal findings in bovine late pregnancy.  相似文献

A 20-year-old Warmblood gelding presented for evaluation and treatment of ventral oedema and azotaemia of unknown aetiology. On presentation, a diastolic heart murmur was appreciated and echocardiography revealed moderate aortic insufficiency due to chronic degenerative valve disease. The horse was hospitalised and failed to respond to oral and i.v. fluids and diuretics. Following discontinuation of all fluid and diuretic therapy, the horse became acutely agitated and developed monomorphic ventricular tachycardia. The ventricular tachycardia spontaneously converted to normal sinus rhythm, however the heart murmur changed in timing to a right basilar continuous murmur and bounding jugular pulses were noted. Repeat echocardiogram revealed an aorto-cardiac fistula with dissection into the basilar interventricular septum and left-sided chamber volume overload that was not previously present. Attempts at stabilisation were unsuccessful and euthanasia was elected. Post-mortem examination confirmed chronic renal disease of unknown aetiology in addition to an aorto-cardiac fistula originating from the right sinus of Valsalva with subsequent dissection into the basilar interventricular septum.  相似文献

Hypereosinophilic syndrome is an uncommon disorder in the cat. It is a heterogeneous group of conditions defined by a persistent hypereosinophilia associated with organ damage directly attributable to tissue hypereosinophilia. A seven-year-old castrated domestic shorthair cat presented to the emergency service for dyspnea. Initial physical examination identified the presence of a grade III/VI systolic left parasternal murmur with no gallop or arrhythmia. A snap N-terminal-pro hormone brain natriuretic peptide was abnormal, and a point-of-care ultrasound revealed mild pleural effusion, scant pericardial effusion, and an enlarged left atrium. There was leukemia (72.35 K/uL, reference range 4.5–15.7 K/uL) predominated by eosinophilia (33.84 K/uL; reference range 0–1.9 K/uL). On echocardiogram, there was concentric hypertrophy of the left ventricular walls with irregular endocardial borders. The left atrium was enlarged with evidence of spontaneous echogenic contrast. The mitral valve was thickened with a vegetative lesion on the anterior leaflet. Despite treatment, the patient experienced cardiopulmonary arrest, and cardiopulmonary resuscitation was unsuccessful. Complete necropsy with histopathology revealed eosinophilic infiltrates in multiple organs and the presence of a severe, acute-on-chronic, fibrinous, and eosinophilic-granulomatous endomyocarditis with mural thrombosis and marked endocardial fibrosis. This case represents an unusual presentation of the hypereosinophilic syndrome in the cat with cardiac involvement and congestive heart failure as a primary clinical sign.  相似文献

A 12-year-old spayed female German shorthaired pointer dog sustained extensive bite wounds around the neck. At presentation, atrial fibrillation was identified with a rapid ventricular response rate of 300 beats per minute (bpm). The ventricular response rate rapidly decreased to 130 bpm following administration of hydromorphone and oxygen. Based on the rate, antiarrhythmic therapy was not initiated. The heart rhythm converted back to sinus rhythm by the time of the first recheck evaluation 2 days later, and the dog remained in sinus rhythm at all subsequent evaluations. With the resolution of the arrhythmia, paroxysmal atrial fibrillation was suspected. The underlying etiology of the arrhythmia was not determined; however, imbalances in autonomic tone associated with trauma and/or direct trauma to the heart were hypothesized.Key clinical message:This report indicates a possible role of imbalances in autonomic tone due to trauma in the development of paroxysmal atrial fibrillation and suggests that it should be a differential diagnostic consideration in patients with atrial fibrillation following trauma. Primary treatment of atrial fibrillation may not be needed in these cases if the ventricular response rate is not rapid, or if there is spontaneous conversion to sinus rhythm.  相似文献

Unilateral testicular enlargement was detected in a 5‐years‐old domestic ferret during a routine sterilization. The right testicle showed two different types of proliferative lesions: (i) round nodules, well demarcated, showing a soft yellow tissue; (ii) white nodules, firm, with irregular‐shaped invaginations. Microscopically, the neoplastic proliferations were identified as an interstitial neoplasm and Sertoli cell tumour, respectively. The left testicle was small and showed intense testicular atrophy. Clinical evaluation of the ferret did not show any other apparent pathological processes. This study is the first case reporting the concomitant occurrence of a Sertoli cells tumour and an interstitial cell tumour in a domestic ferret.  相似文献
