Summary: A woman reported painful thrombosis of the superficial femoral artery 16 months after a transfemoral microcatheter was glued into a cerebral arteriovenous malformation and transected at the groin. When the catheter was removed, a portion was found to be incorporated into the wall of the carotid artery. This case demonstrates that portions of a retained microcatheter may be incorporated into the arterial wall while other portions may remain mobile and cause late peripheral arterial symptoms.
