Iatrogenic femoral artery aneurysms in orthopaedic practice

Abstract

Background: Iatrogenic injury to the femoral vessel is a rare complication after fracture of hip. Pseudoaneurysm formation of superficial femoral artery or profunda femoris artery is detected quite late. We present our experience for surgical management of pseudoaneurysm of femoral artery after iatrogenic trauma during management of fracture of femur.

Methods: A retrospective analysis was carried out for eight patients with femoral artery pseudoaneurysm treated surgically during the last 10 years in one surgical unit.

Results: Of eight patients with pseudoaneurysm of femoral artery, six had superficial femoral artery aneurysm and two profunda femoris artery aneurysm. Mean duration for presentation was 4 months (range 2-6 months). Methods of surgical intervention were direct closure of arterial defect after aneurysmectomy in six cases and use of saphenous vein patch graft for repair of artery in two cases. Mean size of aneurysm was 12 x 7 cm (range 8 x 4 cm to 20 x 12 cm). All patients were doing well during a mean follow up of 72 months (range 6-110 months).

Conclusion: Large pseudoaneurysms of femoral arteries after iatrogenic injury during management of fractures of femur should be managed by aneurysmectomy and arterial repair with or without saphenous vein patch graft.
