Primary venorrhaphy for traumatic inferior vena cava injuries

Primary venorrhaphy for traumatic inferior vena cava (IVC) injury has been criticized because of the potential for stenosis, thrombosis, and embolism. A retrospective study was performed to evaluate the morbidity and outcome of this method. Thirty-eight patients at our institution had traumatic injuries to the IVC between 1994 and 1999. Thirty (79%) were from firearms, five (13%) from stab wounds, and three (8%) from blunt trauma. Six patients died in the emergency department. The remaining 32 patients underwent exploratory celiotomy with 23 survivors and nine intraoperative deaths for a mortality rate of 28 per cent (nine of 32). Vascular control was achieved by manual compression in 44 per cent and by local clamping directly above and below the injury in 38 per cent. All repairs were by primary venorrhaphy, and no patient was treated with patch angioplasty or venous reconstruction. Three patients had caval ligation. Follow-up IVC imaging in 11 patients revealed that the IVC was patent in eight, narrowed in two, and thrombosed below the renal veins in one. One patient developed a pulmonary embolus, The vast majority of traumatic injuries to the IVC can be managed by direct compression or local clamping and primary venorrhaphy. Direct repairs are associated with a low thrombosis and embolic complication rate.
