A one-year-old neutered male cat was referred for a grade IIIA open radius and ulna fracture. The mid-diaphyseal radial and ulnar fractures were associated with lateral radio-humeral and radio-ulnar dislocations. From these abnormalities, a diagnosis of type IV Monteggia fracture was made. The annular ligament was found to be intact on examination and the radial head was correctly positioned and stable after fracture reduction and plate fixation. Eighteen months postoperatively, the cat did not exhibit any signs of lameness or any signs of pain on palpation and mobilisation. Signs of mild osteoarthritis were present on radiographs. Type IV Monteggia fractures are very rare in animals. The combination of a radial head dislocation with an intact annular ligament is uncommon. This pattern allowed a single reconstruction with two plates without a radio-ulnar screw. 相似文献

OBJECTIVE: To determine the sensitivity and specificity of radiographic evaluation of radio-ulnar incongruence in canine elbow joints in vitro. STUDY DESIGN: Radiographic evaluation of induced radio-ulnar incongruence in canine cadaveric forelimbs by radiologists blinded to study design. SAMPLE POPULATION: Six cadaveric canine left forelimbs. METHODS: Extended lateral, 90 degrees flexed lateral, and cranio-caudal projections were taken of the elbow joint of six cadaveric canine forelimbs. A four-pin, type I external skeletal fixator (ESF) with a linear motor side bar was attached to the medial aspect of the radius, and a 2-cm segment of bone was removed from the mid-diaphysis. A 3.5-mm cortical bone screw placed from the medial to lateral styloid processes prevented relative movement between the distal radius and ulna during radial shortening. The ESF was used to progressively shorten the radius in increments of 0.5 mm to a total of 4 mm. The three radiographic projections were repeated after each incremental change of length. After the study, each elbow joint was disarticulated to confirm the presence of a step defect. The original radiographs and three copies were randomized and then evaluated by four radiologists blinded to the study design. Radiologists were asked to evaluate whether the joint was normal or abnormal and if there was evidence of radio-ulnar incongruence. The ability of each radiologist to correctly identify congruent elbows (specificity) and incongruent elbows (sensitivity) was calculated. RESULTS: The median specificity was 86% using the lateral projection and 82% using the cranio-caudal projection. The median sensitivities using the lateral and cranio-caudal radiographic projections were 78% and 79%, respectively. The degree of radial shortening required for individual radiologists to achieve a sensitivity of 90% ranged from 1.5 mm to greater than 4 mm. CLINICAL RELEVANCE: Standard radiographic evaluation for radio-ulnar incongruence in the dog may be associated with relatively poor sensitivity and specificity. Invasive surgical procedures and screening programs that rely on radiographic diagnosis of radio-ulnar incongruence should be discouraged until a more reliable method of diagnosis of this type of elbow joint incongruence is available. 相似文献

An 8-year-old domestic shorthair was admitted with non-weight bearing left forelimb lameness. Examination and radiographs revealed dorso-medial ante-brachiocarpal luxation with palmar luxation of the distal radio-ulnar joint. Primary repair was performed and stabilised using an arthrodesis wire and type Ia Kirschner-Ehmer (K-E) external skeletal fixator (ESF). The cat regained excellent pain-free limb function by 14 weeks with only minor reduction in range of movement. This is the first case report of a cat with distal radio-ulnar joint luxation associated with ante-brachiocarpal luxation. Primary repair of carpal luxation in the cat should be considered before arthrodesis. 相似文献

A six-month-old kitten had congenital urethral sphincter mechanism incompetence due to urethral hypoplasia and associated uterine hypoplasia and vaginal aplasia. Diagnosis was based on radiographic examination, surgical exploration and histological examination of the lower urinary tract. Surgical correction resulted in a marked clinical improvement. The cat became fully continent following treatment with phenylpropanolamine. 相似文献

A 4-month-old Labrador was presented for forelimb lameness and elbow pain. Radiography revealed asymmetric premature closure of the distal radial physis resulting in humeroradial and humero-ulnar subluxation. A four-ring circular external fixator applied to the antebrachium was used to perform distraction osteogenesis. After a 4 day latency period, varying rates of linear distraction were used to lengthen the radius by 50% of its original length, which is significantly longer than has been previously reported. By 69 days after performing the radial osteotomy, the distraction callus had achieved clinical union and the fixator was removed. One year postoperatively, mild lameness was present after exercise and minimal elbow osteo-arthritis was evident radiographically. Complications observed included pin tract drainage, transient carpal contracture and radio-ulnar synostosis. 相似文献

A 2‐year‐old neutered male European short‐haired cat was presented for a persistent discharge from the scar of previous left eye enucleation, performed 6 months prior by the referring veterinarian. A surgical exploration of the orbit was performed and retained nictitating membrane glandular and conjunctival tissues were removed. Eleven days later, the cat developed an orbital pneumatosis caused by retrograde movement of air through a patent nasolacrimal system and diagnosed by survey radiographic examination of the skull. Nasolacrimal system patency was assessed by dacryocystography performed by injection of iodinated contrast medium under pressure into the orbital cavity. Computed tomography dacryocystography confirmed the radiographic findings. The condition resolved following dacryocystography, possibly as an inflammatory response to the contrast medium. To our knowledge, this is the first case of orbital pneumatosis reported in a cat. 相似文献

A domestic shorthair cat examined because of dyspnea was found to have ophthalmoscopic and radiographic changes suggestive of systemic mycosis. The cat died despite antifungal therapy. Histologic examination revealed Blastomyces dermatitidis in the eyes, brain, lungs, stomach, liver, kidneys, spleen, pancreas, and adrenal glands. The pathologic changes were similar, but more widespread than those typically seen with canine blastomycosis. 相似文献

A 7-year-old male, castrated, domestic shorthair cat was presented with a plantigrade stance of the left pelvic limb. An avulsion of the lateral head of the gastrocnemius muscle was diagnosed based on clinical examination and radiographic assessment. Surgical reduction and fixation were achieved with modified locking loop sutures through bone tunnels in the supracondylar tuberosity of the distal femur. Additionally, a temporary calcaneotibial positional screw was placed in order to neutralise forces on the gastrocnemius muscle. No postoperative complications were encountered and the cat made a full recovery. 相似文献

We report a case of primary cardiac lymphoma in a cat, causing pericardial effusion. A 13-year-old castrated male Himalayan cat was evaluated for chronic weight loss and radiographic finding of cardiomegaly. Pericardial effusion and a heart mass were detected via echocardiography. Pericardiocentesis and ultrasound-guided fine needle aspirate of the heart mass were performed under sedation. Antemortem diagnosis of cardiac lymphoma was made based on cytology of pericardial fluid. Based on physical examination, laboratory tests and abdominal radiographs, primary cardiac lymphoma was established as the presumptive clinical diagnosis. Treatment with chemotherapeutic agents was initiated. 相似文献

Xanthine urolithiasis was found in a 4-year-old spayed female Himalayan cat with a 10-month history of intermittent haematuria and dysuria. Ultrasonographs indicated the existence of several calculi in the bladder that were undetectable by survey radiographic examination. Four bladder stones were removed by cystotomy. The stones were spherical brownish-yellow and their surface was smooth and glossy. Quantitative mineral analysis showed a representative urolith to be composed of more than 95% xanthine. Ultrasonographic examination of the bladder 4.5 months postoperatively indicated the recurrence of urolithiasis. Analysis of purine concentration in urine and blood showed that the cat excreted excessive amounts of xanthine. In order to test the hypothesis that xanthinuria was caused by a homozygote of the inherited mutant allele of a gene responsible for deficiency of enzyme activity in purine degradation pathway, the allele composition of xanthine dehydrogenase (XDH) gene (one of the candidate genes for hereditary xanthinuria) was evaluated. The cat with xanthinuria was a heterozygote of the polymorphism. A single nucleotide polymorphism analysis of the cat XDH gene strongly indicated that the XDH gene of the patient cat was composed of two kinds of alleles and ruled out the hypothesis that the cat inherited the same recessive XDH allele suggesting no activity from a single ancestor. 相似文献

A 4-year-old castrated domestic shorthair cat was referred for treatment of chylothorax. Thoracic duct lymphangiography revealed partial obstruction of the cranial vena cava, as evidenced by filling of mediastinal lymphatics with dye instead of all of the dye entering the vena cava. The thoracic duct was ligated via left 10th intercostal space thoracotomy. Immediate postligation lymphangiography revealed successful duct ligation. Results of a serum ELISA for adult heartworm antigen that was performed before surgery were positive. Drug treatment for the heartworm disease was not recommended, because the pleural effusion had ceased (as determined by radiographic examination 3.5 and 9 months after surgery) and the cat was doing well clinically. Sixteen months after surgery, the owner reported that the cat was doing well and did not have signs of respiratory problems. 相似文献

A heart murmur was detected in a five-month-old Persian chinchilla cat. The animal was referred to Nihon University Animal Medical Center where radiographic examination revealed an enlarged heart with dilation of pulmonary arteries and veins and pulmonary oedema. Echocardiography revealed partition of the left atrium, with turbulent blood flow within the left atrium. The patient was placed under continuous care at the facility, but died at seven months of age. Postmortem examination revealed that the left atrium was partitioned by a fibromuscular septum, with a 1 mm diameter perforation, consistent with a diagnosis of cor triatriatum sinister. 相似文献

A 12-year-old, spayed, female domestic shorthair cat was diagnosed with severe and extensive hypertrophic osteopathy of the appendicular skeleton. Diagnostic ultrasound detected a mass lesion in the right adrenal gland. A right adrenalectomy was performed, and histopathological examination confirmed an adrenocortical carcinoma. No radiographic evidence of pulmonary metastasis was found on initial presentation or recheck thoracic radiographs taken 15 weeks later. Almost complete regression of periosteal new bone formation occurred 15 weeks following the successful surgical removal of the adrenal tumor. 相似文献

The normal radiographic appearance of the feline upper gastrointestinal (UGI) examination following oral administration of barium sulfate suspensions was described. Important findings included the minimal gastric air and small bowel gas present on survey abdominal radiographs. Gastric appearance was nearly constant. A normal duodenal pattern, referred to as a "string of pearls", was described. Small bowel lumen size was consistently less than 12 mm. Small bowel mucosal patterns varied widely. The most commonly identified normal radiographic UGI patterns in this study were found consistently in a group of 26 cats thought to be without gastrointestinal disease. Because of the consistency of observation of many radiographic patterns, rapid gastric emptying, and a short small bowel transit time, normal UGI examinations in the cat present a more constant appearance than in the dog, thus making them more valuable as well as easier to conduct. 相似文献

: A domestic-longhair cat presented due to lethargy, dyspnoea and hypersalivation. Radiographic examination revealed a bilateral pleural effusion, which was diagnosed as pyothorax based on cytological examination. Ultrasonographic examination revealed extensive loculations within the thoracic cavity. Exploratory sternotomy, under general anaesthesia, allowed the removal of approximately 100 ml of purulent fluid and debridement of a partially walled-off abscess and necrotic material from the pleural cavity. Postoperative positive-pressure ventilation was required due to severe respiratory depression. Intensive postoperative care, including intensive continuous monitoring, thoracostomy tube drainage and lavage of the pleural cavity and oesophagostomy tube feeding, was performed. Complete resolution of clinical signs had occurred by 15 days postoperatively. Clinical or radiographic abnormalities were not detected at a follow-up examination one year after surgery. 相似文献

An aged domestic short-haired cat was presented for examination because of a six week history of weight loss, diarrhoea, and increased appetite. Clinical examination revealed the cat to be emaciated, icteric and the liver was enlarged. Laboratory tests confirmed the presence of hepatic disease and radiographic examination showed hepatomegaly and ascites together with an enlarged globular heart. Ultrasonography showed a heart of normal size surrounded by tissue and/or fluid within the pericardial sac. Following euthanasia, necropsy revealed the presence of ectopic hepatic tissue within the pericardial sac. Both normally positioned liver and the intrapericardial hepatic tissue showed chronic active pericholangitis and nodular hyperplasia. There was no evidence of a diaphragmatic peritoneal-pericardial hernia, but the intrapericardial mass was connected to the liver by a thin cord of tissue ventral to the caudal vena cava. 相似文献

Erosive polyarthritis was diagnosed in an 11-month-old neutered male Egyptian Mau-cross cat with concurrent glucocorticoid-responsive dermatitis. Clinical signs, synovial fluid analysis, serological tests and radiographic appearance could not differentiate between immune-mediated and infective arthritis. Mycoplasma gateae was isolated by strictly anaerobic culture of the synovial fluid. Treatment with Enrofloxacin led to a rapid improvement of the cat's condition. Two months later the cat was euthanased because of severe glomerulonephritis and direct Coombs' test positive anaemia, possibly caused by mycoplasma infection. M gateae could not be isolated at post-mortem examination. 相似文献

A case of hypervitaminosis A with secondary entrapment and compression of the left brachial plexus nerve roots is described. A 9-year-old male castrated domestic shorthair, fed a home-made diet based on raw pork liver, was submitted for examination for a left forelimb lameness that evolved to paralysis over a 2-month period. Clinical examination revealed a flaccid paralysis and atrophy of all left forelimb muscles. An ipsilateral Horner's syndrome was also noted. Radiological examination of the cervical and thoracic spine showed massive new bone formation at the ventral aspect of the second cervical to sixth thoracic vertebra. The diagnosis of hypervitaminosis A was made, based on the clinical and radiographic findings, as well as the determination of serum vitamin A concentration, which was 630 microg/dl, three times above the upper normal limit for this species. Despite the unfavourable initial prognosis, the cat progressively regained function of the affected limb approximately 6 months after the diet was changed to a commercial canned food. 相似文献

An eight-year-old neutered female domestic longhair cat was presented with icterus and a palpable cranial abdominal mass. The cat had undergone an open biopsy of the liver two years previously. Abdominal radiographic findings included a solitary soft tissue mass originating from the right cranial hepatic region. An anechoic cystic structure was identified on ultrasound examination. Surgical exploration revealed the cyst to be filled with bile. The fibrous capsule of the cyst originated in the liver. Severe hepatic lipidosis was also present. It is believed that the bilorna was a complication of the previous hepatic biopsy and not a sequela of hepatic lipidosis. 相似文献
