A 23-year-old man with a gunshot injury to the abdomen and cardiac arrest requiring emergency department thoracotomy had a transection of the distal inferior vena cava (IVC) and small bowel injury. Because of persistent hemorrhagic shock, the IVC was ligated. During the next 3 days, he developed worsening bilateral leg edema. He was taken back for reanastomosis of his small bowel and reconstruction of the IVC using autologous femoral vein harvested from the right leg. We think that patients requiring ligation of the vena cava with worsening leg edema can benefit from a staged reconstruction of the IVC. (J Vasc Surg Cases and Innovative Techniques 2017;3:136-8.) Penetrating injuries of the inferior vena cava (IVC) carry a high mortality. [1][2][3][4][5] In a hemodynamically unstable patient, ligation of the vena cava often becomes necessary as a lifesaving measure. We describe a delayed reconstruction of the IVC using autologous femoral vein after stabilization of the patient. This case demonstrates the value of working with the trauma team in successful resuscitation of severe shock, acidosis, and hypothermia and in control of abdominal contamination before a venous bypass. The patient has consented to this case presentation.
CASE REPORTA 23-year-old man arrived in the trauma bay with severe hypotension after a gunshot injury to the abdomen. During emergency department resuscitation, the patient arrested, requiring thoracotomy and aortic cross-clamping. The patient was placed on massive transfusion protocol and transported to the operating room for exploration, with findings of a transected distal IVC involving both origins of the common iliac veins. His aorta and iliac arteries were intact. Because of his persistent hemorrhagic shock, the IVC and both iliac veins were ligated (Fig 1).A segment of small bowel was also injured and treated with we harvested the right femoral vein, between the deep and popliteal veins, and created a bifurcated bypass (Fig 2). The patient was discharged home on clopidogrel and graded compression stockings. His venous duplex ultrasound study at 2 weeks showed a patent bypass. At 1-month follow-up, his incisions were healed and he had no residual leg edema.
DISCUSSIONIVC injuries are rare and more often the result of penetrating trauma, occurring in approximately 0.02% of gunshot wounds to the abdomen. 2,6 Mortality of IVC injuries is quoted in most series to be around 50%. 1,2 Factors associated with increased mortality are hypotension on arrival to the emergency department, associated major vascular injury, and level of IVC injury, with proximal injuries carrying the highest mortality (suprahepatic).
