Venous injuries of the lower extremities and pelvis: repair versus ligation.

Many surgeons advocate repair of venous injuries to prevent the sequelae of venous ligation. Since 1986, we have treated 74 patients with 79 venous injuries of the lower extremity or pelvis. There were 68 men and six women with a mean age of 29.2 years (range, 16-62 years). The mechanisms of injury were gunshot wounds in 61 patients, stab wounds in 11 patients, and shotgun wounds and blunt trauma in one patient each. Forty-eight injuries were treated by ligation; 31 injuries were treated by repair. Repairs included two interposition grafts, eight end-to-end repairs, 16 venorrhaphies, and five vein patches. In addition, we developed a venous injury staging system (VIS), which ranged from grade I (less than 50% laceration) to grade IV (complete interruption with soft-tissue injury). Patient age, mechanism, location of injury, associated injuries, and incidence of arterial injury were not different between the patients treated by ligation and those treated by repair. Patients treated with venous ligation had a greater VIS (mean, 3.45 vs. 2.0), a greater incidence of shock (71% vs. 39%), and higher transfusion requirements (9.23 vs. 4.82 units). Postoperative morbidity rates were identical, however. There was no increase in the need for fasciotomy in patients treated with venous ligation. Eighty-six percent of the patients treated by ligation were totally free of edema at discharge. The others had only mild edema that did not interfere with daily activities at discharge and follow-up. Ligation is a safe alternative to repair in patients with injuries to the lower extremities or pelvis.(ABSTRACT TRUNCATED AT 250 WORDS)
