Segments of jejunum that had been subjected to ischemia 1 month previously were resected en bloc in six horses. Everted end-to-end anastomoses were performed by application of double rows of stainless steel staples. The anastomotic sites were examined at 3 weeks, 3 months, 6 months, and 8 months postoperatively. All but one of the horses experienced colic at some point after the second postoperative week. At 3 weeks, there was extensive adhesion and stricture formation associated with the anastomoses. With increasing time postoperatively, there were progressively less severe adhesions and strictures. At 6 and 8 months, there was separation of the muscularis with noticeable thinning at the anastomotic site. 相似文献

To facilitate blood collection from blood donor dogs, arteriovenous fistulas were established between the common carotid arteries and external jugular veins in five adult dogs. Twelve to 16 mm, side-to-side anastomoses were created using simple interrupted 6–0 polypropylene sutures. Starting 1 month after the surgical procedure, 500 ml of blood was collected from each dog as required. Electrocardiography, thoracic radiography, and cardiac output and rate were used to monitor cardiac changes. Blood flow characteristics, and proliferative and dystrophic cellular changes occurring in the vessels were documented in one dog.
The mean blood collection times were 2 minutes and 45 seconds from the fistula site and 9.0 minutes from the opposite jugular vein. Ventricular hypertrophy and myocardial changes were observed on electrocardiogram in two dogs, and radiographic evidence of pulmonary hypertension was noted in three dogs. Reversed blood flow was documented in the common carotid artery and external jugular vein distal to the arteriovenous fistula. Four dogs were still in use as blood donors 1 to 1 1/2 years after establishment of the fistulas. Clinical signs of congestive heart failure were not observed. 相似文献

The medical management of three horses with simple and strangulating small intestinal obstructions was unsuccessful and was therefore supported by surgical bypasses. Jejunocecostomies were used to treat horses with postoperative paralytic ileus that was unresponsive to medical management. These horses had abdominal pain, gastric distention, heart rate elevations greater than 60/minute, and small intestinal distention on rectal palpation. Two horses experienced weight loss which responded to bypass removal. The bypass effectively decreased the need for intravenous fluid administration and repeated nasogastric intubation. 相似文献

Complete displaced lateral condylar fractures of the metacarpus with triangular osteochondral fragments at the palmar articular surface occurred in two Thoroughbred horses. The condylar fractures were repaired with cortical bone screws following removal of the osetochondral fragments via a dorsal arthrotomy and distraction of the condyles. One horse raced successfully after surgery, and the other is being used successfully as an English pleasure mount. 相似文献
