Intravenous digital subtraction angiography of arteriovenous fistulas and shunts for hemodialysis.

Surgical reconstruction of vascular access in hemodialysis patients requires solid information on the site and type of the shunt failure. In 21 cases (16 patients) analysis of angioaccess failure included digital subtraction angiography. With this technique, information on anatomy and rheological pattern enabled us to plan specific surgical procedures during which preoperative diagnoses were confirmed.
