Transvenous Fogarty balloon catheter occlusion of an iatrogenic innominate artery to innominate vein fistula.

Transvenous embolization therapy is reported in a patient who developed a fistula from the innominate artery to the innominate vein as a complication of permanent cardiac pacemaker insertion. A transarterial approach at occlusion was unfavorable due to previous difficult catheterizations, and the patient's poor clinical condition precluded alternative operative intervention. The fistula was successfully closed by transvenous placement of a Fogarty nondetachable balloon catheter after coil and detectable balloon placement attempts were unsuccessful.
