Angioplasty-induced pseudoaneurysm successfully treated with a Palmaz stent. A case report.

Pseudoaneurysm formation and vessel rupture are considered rare complications of percutaneous transluminal angioplasty (PTA), and few reported cases exist in the literature. The true incidence of pseudoaneurysm formation is unknown, for follow-up angiography is not routinely performed unless symptoms recur or persist. Currently, the only intervention widely accepted for angioplasty-induced pseudoaneurysm involves surgical excision or repair. The authors describe a case of successfully treated pseudoaneurysm with a noncovered stent.
