Case Description—A 9-month-old domestic shorthair cat was evaluated after being struck by a car.

Clinical Findings—The cat had a fractured tibia and avulsion of the tail base. Motor and deep pain sensation were absent from the tail. The fractured tibia was repaired 2 days after the trauma. On the third day, the cat developed tachypnea, dyspnea, high serum urea nitrogen and total bilirubin concentrations, epistaxis, persistent hypotension, and oliguria. The cat recovered with supportive care but developed extensive necrosis of the skin on the dorsum by 9 days after the initial trauma.

Treatment and Outcome—The skin was debrided from the caudal portion of the scapula to the anus and down each pelvic limb to the level of the distal portion of the femur. The tail was amputated. Wet-to-dry bandages were applied to the wound for 3 days. Approximately 50% of the wound underwent delayed primary closure, and the remainder was managed with vacuum-assisted closure. A healthy granulation bed was quickly established. Vacuum-assisted closure was also applied after graft application. Graft acceptance was 100%, and use of the vacuum-assisted closure bandage was not associated with the complications associated with the traditional bandage.

Clinical Relevance—Vacuum-assisted closure is a useful, easily applicable technique for open and grafted wounds, even when wounds are in challenging anatomic locations.

Results of abdominal ultrasonography in 63 dogs and cats with suspected congenital portosystemic shunts (PSS) were compared with surgical, portographic, and necropsy findings. True-positive ultrasonographic results were found in 33 animals, and 2 animals had falsepositive results for detection of single extrahepatic PSS. In 4 animals, results were true negative and in 8 animals, were false-negative for detection of extrahepatic PSS. The false-negative rate decreased substantially with operator experience. The sensitivity of ultrasonography for detection of extrahepatic PSS in these animals was 80.5%, and the specificity was 66.7%. In 5 other animals, ultrasonographic examination was strongly suggestive of the existence of a shunt, but the vessel could not be definitively imaged. All 5 animals had single extrahepatic shunts. Eleven animals had true-positive results for detection of intrahepatic PSS. One animal had false-positive ultrasonographic results for intrahepatic PSS, but an extrahepatic shunt was diagnosed at surgery. The sensitivity of ultrasonography for detection of intrahepatic PSS was 100%.
