European Journal of Trauma and Emergency Surgery Case Study Traumatic Injury of the Superior Mesenteric Vein: Ligate, Repair or Shunt?

We report a case of SMV injury in a critically ill patient. The patient was a 19-year-old woman involved in a motor vehicle collision. Her injuries included grade II splenic and renal lacerations, devascularized and lac erated right and transverse colon, a transected trans verse mesocolon, a massive shear injury of her abdominal wall, and two partial SMV transections. At initial damage control laparotomy, the SMV was ligated, the devascularized bowel resected and a temporary abdominal closure applied. At re-operation, a mesocaval shunt using saphenous vein was employed. The shunt failed and the patient required a saphenous vein jump graft. Although visceral vascular injuries are rare, ligation of the SMV in a damage control situation is acceptable. This case study is the first to discuss appropriate treatment when interrup tion to a patient’s collateral visceral venous drainage limits the surgeon’s ability to ligate. In these situa tions, bypass shunts may be successful
