Arterial injuries of the extremities.

Fifty-eight patients with arterial injuries of the extremities were treated during the past 8 years. Fifty-one had acute injuries and seven had nonacute injuries. Blunt trauma or shotgun wounds caused 74% of the injuries, and 55% were associated with skeletal trauma. All the acute injuries endangered the limb; the average ischemic time was 8.5 hours. Brachial, popliteal, and superficial femoral arterial injuries were seen most frequently. Repair was accomplished with autogenous saphenous vein grafts in 47% and end-to-end anastomosis in 41%. Six patients died, four due to injuries of other organs. The most alarming complication of arterial repair was secondary hemorrhage which occurred in three patients and was caused by local infection. Six patients (13.3% required amputations; the highest number (three) after injuries of the popliteal artery. The injuries leading to amputations had associated prolonged ischemia, severity of injury, and associated venous, soft tissue, and skeletal injury. The nonacute injuries were in the form of false aneurysms, pulsating hematomas, AV fistula, and delayed bleeding. These were easily managed without any significant complication.
