A 4-year-old Rhodesian Ridgeback had acute onset of vomiting, lethargy, and discolored urine. Physical examination revealed lethargy, pyrexia, weak femoral pulses, cardiac arrhythmia, distended abdomen, and signs of pain on abdominal palpation. Abdominal radiography and ultrasonography revealed a gas-containing lesion in the cranial portion of the abdomen. Preoperative care included administration of fluids, antibiotics, and antiarrhythmic medication. Exploratory laparotomy revealed hemobilia and a 360 degrees clockwise torsion of the papillary process of the caudate lobe of the liver. Clinical signs resolved completely after liver lobectomy, and the dog was alive 2 years after surgery. Torsion of a liver lobe is rare in dogs. Necrosis of the involved liver lobe can result in acute weakness, shock, and death. Hemodynamic stabilization, antibiotic treatment, and surgical intervention have been successful in treating this condition. Liver lobe torsion should be considered on the differential diagnoses list of acute abdominal pain.
一只4岁的罗德西亚脊背犬突然出现呕吐、嗜睡和尿液变色症状。体格检查发现嗜睡、发热、股动脉搏动微弱、心律失常、腹部膨隆以及腹部触诊有疼痛迹象。腹部X线摄影和超声检查显示腹部头侧部分有一个含气病变。术前护理包括给予液体、抗生素和抗心律失常药物。剖腹探查发现肝内胆血症以及肝尾状叶乳头突顺时针360度扭转。肝叶切除术后临床症状完全消失，该犬术后存活了2年。肝叶扭转在犬中较为罕见。受累肝叶的坏死可导致急性虚弱、休克和死亡。血流动力学稳定、抗生素治疗和手术干预已成功治疗了这种疾病。肝叶扭转应列入急性腹痛的鉴别诊断清单。
