Percutaneous embolization of subclavian pseudoaneurysmatic arteriovenous iatrogenic fistula by steel coils.

A case of iatrogenic subclavian arterio-venous fistula with pseudoaneurysm formation is described. Treatment by means of percutaneous embolization, on the venous side, with steel coils has been successful; in order to avoid complications, the arterial side was blocked by an angioplasty balloon. After discussing the more common complications of subclavian vein puncture, the Authors conclude that percutaneous embolization is a valuable alternative to surgery even in such a lesion, especially when the surgical risk is high.
