FEMOROPOPLITEAL ARTERIOVENOUS ANEURYSM CAUSED BY FRACTURED OSTEOCHONDROMA OF THE FEMUR

Abstract

Arteriovenous aneurysms of the extremities are usually caused by penetrating wounds (such as bullet or stab), but those due to a penetrating osteochondroma must be very rare. Paul 1 reported such a case in a 22-year-old man with multiple congenital osteochondromas, one of which penetrated the popliteal artery giving rise to an aneurysm with painful swelling of 17 days' duration. At the time of the operation, a pulsating hematoma or false aneurysm was found with a single hole in the popliteal artery. There was no venous involvement, and the artery was restored by suturing of the perforation. Paul reported that the dorsalis pedis and posterior tibial pulses did not return after surgery but that the patient was walking with ease. Hudson 2 reported another case of a traumatic aneurysm in a 14-year-old boy with multiple osteochondromas. This patient gave a history of vigorous bicycling for two hours before sudden onset
