Acute pseudoaneurysm of the femoral artery after repeated trauma in full-contact karate practice

Abstract

Traumatic pseudoaneurysms of the deep femoral artery are only encountered infrequently in sports medical literature. We present the case of a male who, after practising full-contact karate, experienced pain and oedema in the right thigh. The ultrasound results and the arteriography showed the presence of a pseudoaneurysm in a branch of the deep femoral artery. Traumatic pseudoaneurysms of the deep femoral artery are normally secondary to endovascular interventions or to mycotic infections in injecting drug users. The majority appear asymptomatically as a pulsatile mass, although on occasions clinical signs of compression (pain, neurological or venous symptoms) may occur or, if the aneurysm bursts, hypovolemic shock.
