The account alleges that during a peripheral vascular angiogram of a patient's right leg, the catheter tip detached.The clinician had acquired left retrograde femoral artery access and had negotiated the patient's steep ilio-femoral conduit with a guidewire and the 5f catheter.During an over-the-wire catheter exchange within the patient's calcified iliac bifurcation, the catheter tip detached.The physician used a vascular snare device to successfully externalized the foreign body via bilateral femoral artery access thus liberating the vessel.The foreign body retrieval was complicated by a thrombogenic reaction caused by the detached foreign body with thrombosis noted within the common iliac, external iliac, and the profunda arteries.The patient was put on heparin infusion overnight, however due to the continued ischemic complications, the adverse event resulted in a below knee amputation.
