Pseudoaneurysm formation is commonly encountered during the life of a dialysis fistula. When these become excessively large or numerous, surgical revision of the graft has been the only treatment option. The authors have treated seven patients by using percutaneous placement of a detachable balloon to occlude a pseudoaneurysm of an upper extremity graft. In four cases the balloon was directed into the pseudoaneurysm from a femoral artery approach. In three cases a direct puncture was made into the pseudoaneurysm for placement of the balloon. The patients were followed up from 1 week to 7 months. Initial technical success was achieved in all seven cases with no complications. Thrombosis of two grafts occurred during the first week after the procedure: one because of herniation of the balloon out of the pseudoaneurysm and one for unknown reasons. One balloon was inadvertently punctured and deflated during subsequent dialysis. Treatment in the other four cases was successful, as evidenced by no further enlargement of the pseudoaneurysms. Direct puncture of the pseudoaneurysm simplifies the procedure and probably decreases the likelihood of balloon herniation because of the orientation of the balloon.
