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.
一只两岁的杂种雄性犬在遭遇机动车事故三天后前来就诊。X线平片显示多处骨盆骨折，腹腔和腹膜后对比不佳。超声检查显示左肾灌注不良，在左肾动脉起始处可见血栓。超声引导下细针穿刺证实腹膜后和腹腔内可见的游离液体为血液。在43小时内，肾脏灌注未见改善，且这段时间肠道蠕动减弱情况加重。在这43小时内，腹腔积血和腹膜后积血在超声检查下均已消退。手术证实左肾动脉在距主动脉起始处约10毫米处发生撕脱，左输尿管在肾盂输尿管连接处发生撕脱。对左肾实施了输尿管肾切除术，犬恢复顺利。
