Large femoral aneurysm as a late complication after vessel closure device application.

Four months after a diagnostic coronary angiography followed by application of a vascular closure device, a female patient presented with an acute femoral pulsing tumor with strong pain in the groin area. There was no prior trauma. Color duplex sonography showed a large pseudoaneurysm of the right femoral artery. In addition, signs of an old hematoma were documented. Due to the large tumor affecting the arterial perfusion of distal arteries, the pseudoaneurysm was treated immediately by thrombin injection. After this procedure, arterial perfusion in the tumor was not detectable anymore and local symptoms decreased rapidly. This is a rare case of late pseudoaneurysm after femoral artery puncture.
