Avulsion of the left renal artery following blunt abdominal trauma in a dog.
A two-year-old, male, crossbreed dog was presented three days after being involved in a motor vehicle accident. Survey radiographs showed multiple pelvic fractures and poor intraperitoneal and retroperitoneal contrast. Ultrasound indicated the left kidney to be hypoperfused, and a thrombus was visible at the origin of the left renal artery. Ultrasound-guided fine needle aspiration confirmed that free fluid visible in the retroperitoneal and peritoneal spaces was blood. No improvement was seen in the renal perfusion over a 43 hour period, and the intestinal hypomotility worsened over this time. The haemoperitoneum and the haemoretroperitoneum both resolved ultrasonographically within this 43 hour period. Surgery confirmed an avulsion of the left renal artery approximately 10 mm from its origin on the aorta and an avulsion of the left ureter at the ureteropelvic junction. An ureteronephrectomy was performed on the left kidney and the dog recovered uneventfully.
