Retrospective patient-based research.

Brief Description of Project:

Rupture of an arteriovenous shunt during angioplasty is seen in 1-3% of cases. When it occurs, therapy must halt bleeding and also maintain patency of the shunt. Prior therapy has included prolonged angioplasty and the use of metal stents. While both of these methods can afford a technically adequate result, the long-term patency is poor. During the past several years we have used graft-covered stents to treat angioplasty-induced rupture in dialysis shunts. The project calls for review of our existing database, evaluation of the technical, 6-month, and 12-month dialysis shunt circuit patency using our existing database.
