Computerized tomography in the investigation of groin masses following femoral catheterization.

Pseudoaneurysm of the femoral artery is an uncommon complication of retrograde arteriography. It is sometimes difficult to clinically differentiate a pseudoaneurysm from a large hematoma. We present 13 cases of suspected femoral pseudoaneurysm following angiography which were investigated by computed tomography (CT). It is suggested that this is a useful procedure in the investigation of groin masses after catheterization.
