A Ryukin goldfish was evaluated because of a 6-month history of progressive abdominal distention and positive buoyancy. Overinflation of the swim bladder was diagnosed, and the fish was anesthetized with tricaine methanesulfonate. Archimedes' principle was used to determine the volume of swim bladder that was removed surgically. The caudal swim bladder was exteriorized through an abdominal incision and 2 surgical clips were placed across it to limit its size. After surgery, the fish remained in a state of negative buoyancy in sternal and lateral recumbency on the bottom of the tank. Sutures were removed 15 days after surgery, but the fish died 24 days after surgery. A full necropsy could not be performed because of autolysis of the tissues, but the surgical clips and the swim bladder appeared unremarkable. Pneumocystoplasty may be a viable treatment for this condition. 相似文献

Background
Transjugular liver biopsy (TJLB) is used in humans at risk of bleeding. There are no reports of its use in veterinary medicine.Objective
To assess the efficacy and potential complications of TJLB in canine cadavers, and compare with samples obtained via needle liver biopsy (NLB) and surgical liver biopsy (SLB).Animals
Twenty‐five medium and large breed canine cadavers.Methods
Prospective study. TJLBs were procured through the right jugular vein. After biopsy, intravenous contrast and gross inspection were used to assess the biopsy site. Minor and major complications were recorded. NLBs and SLBs were then obtained. Histopathology was performed, and TJLB and NLB were compared for number of complete portal tracts (CPTs), length, and fragmentation. Pathologic process and autolysis were assessed in all samples.Results
All TJLBs yielded liver tissue. The proportion of minor complications was 12/25 (48%), and major complications 16/25 (64%); 13/16 (81%) of the major complications were liver capsule perforation. In 21/25 (84%), the histopathology in the SLB was reflected in the TJLBs. For cases with minimal autolysis, median number of CPTs in TJLBs was 7.5, compared with 4 in NLBs (P = .018). Median length of TJLB specimen was 28 mm compared to 22 mm in NLBs (P = .007). Fragmentation rate was median of 1.25 for TJLB compared to 1.50 in NLBs (P = .11).Conclusions and Clinical Importance
TJLB is technically feasible and achieves comparable results to NLB and SLB. The number of complications, in particular liver capsule perforation, was greater than expected. Further studies are indicated before clinical use is recommended. 相似文献3.

A retrospective study was performed on 31 dogs with completely excised, grade II, cutaneous mast cell tumors in order to determine recurrence rates and sites. Distant tumor recurrence developed in 22% of dogs, and local tumor recurrence developed in 11% of dogs; however, the vast majority of these animals were incompletely staged initially. Complete surgical excision of grade II mast cell tumors was associated with effective local control in 89% of these dogs. Therefore, adjuvant radiation therapy might not be indicated in the majority of dogs with complete surgical excision. 相似文献

A 3-month-old sexually intact male German Shepherd Dog was evaluated because of signs of depression, ataxia, and collapse. Clinicopathologic abnormalities included low serum BUN and albumin concentrations and high serum liver enzyme activities and plasma ammonia and serum bile acids concentrations. Abdominal ultrasonography revealed an intrahepatic portosystemic shunt (PSS). The dog was anesthetized; via a transjugular approach, guidewires and catheters were directed with fluoroscopic guidance to locate the shunt and determine its anatomic features. Minimal changes in portal vein pressure during temporary shunt balloon occlusion enabled complete shunt attenuation, which was performed by use of a self-expanding septal occlusion device that is typically used for treatment of atrial septal defects in humans. Following initial misplacement of the device, the procedure was repeated successfully 2 months later and resulted in complete shunt occlusion. One year after this second procedure, the dog was clinically normal and serum bile acids concentration was within reference limits. In certain dogs with intrahepatic PSSs, treatment with minimally invasive interventional techniques involving fluoroscopy may reduce the morbidity and mortality rates associated with more invasive surgical procedures. 相似文献

Spontaneous resolution of iatrogenic chylothorax in a cat 总被引:1,自引:0,他引:1
Greenberg MJ Weisse CW 《Journal of the American Veterinary Medical Association》2005,226(10):1667-70, 1659
Chylothorax is an uncommon condition of dogs and cats defined by the accumulation of chylous effusion within the pleural space. Chylothorax has been experimentally created in dogs and cats by ligation of the cranial vena cava and has been reported to occur spontaneously in dogs with naturally occurring obstruction of the cranial vena cava. In the cat of this report, iatrogenic chylothorax was caused by surgical ligation and transection of the left brachiocephalic vein during a tracheal resection and anastomosis procedure. The chylous effusion resolved with medical management 9 weeks after surgery. 相似文献

OBJECTIVE: To determine survival times in dogs with right atrial hemangiosarcoma treated by means of pericardectomy and tumor resection, with or without adjuvant chemotherapy, and identify complications associated with treatment. DESIGN: Retrospective study. ANIMALS: 23 dogs. PROCEDURE: Dogs were included only if the diagnosis was confirmed histologically. RESULTS: The most common initial complaints included acute collapse (8 [35%] dogs), anorexia or inappetence (8 [35%]), and lethargy (8 [35%]). The most common physical examination abnormalities included muffled heart sounds (12 [52%] dogs), tachycardia (7 [30%]), and weak pulses (7 [30%]). Postoperative complications developed in 12 (52%) dogs; however, most complications were minor. Twenty (87%) dogs were discharged from the hospital. Survival time was significantly longer in the 8 dogs that received adjuvant chemotherapy (mean, 164 days; median, 175 days) than in the 15 dogs that did not receive chemotherapy (mean, 46 days; median, 42 days). Dogs that received chemotherapy were significantly younger and had significantly lower WBC counts than did dogs that did not receive chemotherapy. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that in dogs with right atrial hemangiosarcoma, surgical resection of the tumor was associated with a low complication rate and complications that did arise typically were minor. In addition, use of adjuvant chemotherapy following resection was associated with significantly longer survival times, compared with resection alone. 相似文献
