Trauma to the femoral arteries corresponds to 30 percent of all arterial traumas. The authors reviewed 74 patients with noniatrogenic trauma of the femoral arteries treated from January 1991 to December 1993. Ages ranged from 11 to 50 years, with a mean of 24. Seventy-one patients were male and three female. Fifty-two patients (70.2 percent) were white, 20 (27 percent) were black and two (2.8 percent) were Asian. Trauma due to firearms had the highest incidence, with 61 cases (82.4 percent). Absence of pulse was the most frequent clinical symptom (62.5 percent). Severe ischemia, with risk of loss of limb, was found in 66.2 percent of the cases. The superficial femoral artery was impaired in 77 percent of the cases. A preoperative arteriography was performed on only five patients, victims of multiple penetrating trauma or an asymptomatic penetrating wound along a vessel passage. In six cases, arterial and venous ligature was the chosen procedure. In three cases, a primary arterial anantomosis was performed. Simple arterriorraphy was feasible in one patient. In 64 of the patients, a venous graft was undertaken using a segment of the inverted great saphenous vein withdrawn from the other lower limb. Fasciotomoy was used in 32 patients (43.2 percent), all of whom exhibited pasting of the lower limb muscles at admission. One patient died during the immediate postoperative period as the result of multiple organ failure caused by polytraumatism. Preservation of the limb was attained in 72 patients (97.3 percent) Severe, previously-incurred ischemia was responsible for the only two amputations, aggravated by an exceedingly long delay between the time of injury and surgery. One of these patients, in addition to severe ischemia, had extensive injuries to the soft tissues. We conclude that trauma of the femoral arteries, attended while the limb still maintains its vitality, has a positive clinical outcome with a high rate of limb preservation. Mortality usually results from injury to other organs.
