Microcatheter embolization of arteriovenous fistulas in the subclavian region. Report on three cases.
OBJECTIVE
The retrospective evaluation is presented of 3 patients treated with endovascular embolization of arteriovenous fistulas (AVFs) in the subclavian region.


METHODS
Three patients, 2 women and one man, were treated endovascularly in local anesthesia using microcatheters and fibered platinum microcoils. Two patients were asymptomatic and one had unexplained chest pain.


RESULTS
All 3 AVFs were successfully occluded. One coil slipped through the fistula into the pulmonary circulation but caused no clinical sequelae.


CONCLUSIONS
AVFs in the subclavian region can be treated by using microcatheters and fibered platinum microcoils.
