Embolization of profunda femoris artery branch pseudoaneurysms with ethylene vinyl alcohol copolymer (onyx).
This report describes the use of a new embolic agent, Onyx, which is composed of ethylene vinyl alcohol copolymer dissolved in 8% dimethyl sulfoxide, in the endovascular transcatheter embolization of traumatic profunda femoris artery branch pseudoaneurysms in three cases. Two of the cases involved massive thigh swelling after penetrating injury and the other involved massive hemorrhage at the site of a surgical fixator pin. Diagnostic angiography revealed pseudoaneurysm formation of the profunda femoris artery branches in all cases. Immediate control angiography after the embolization procedures demonstrated complete closure of the pseudoaneurysms. During the follow-up period there was no recurrent bleeding. The advantages of Onyx over conventional liquid embolic agents and coils are discussed.
