title: [Insufficiency of arteriovenous fistulas in patients with end-stage renal failure--emergency surgical procedures].
abstract: From 1.07.1994 to 30.06.2001 in the 2-nd Department of Surgery and Department of Nephrology Collegium Medicum Jagiellonian University, in 274 patients with terminal renal failure 341 vascular access for hemo-dialysis have been performed. Acute insufficiency in functioning arteriovenous fistulas occurred in 93 patients. In six of them, an attempt of thrombectomy was done. In 56 patients (group I) we carried out the new fistula on the same vascular level. In the remaining 31 cases (group II) we were forced to perform the procedure at a higher level. To compare late results in both groups of patients the method of Life Table Analysis was used. Cummulated index of patency (Pk) in the time interval 10-12 months in two groups was 0.67. In the time interval 49-54 month in group I, Pk dropped to 0.38, in group II was 0.57. The study we carried out indicates that creation of vascular access on arterialized vessels, being profitable in many aspects, does not provide such long efficient functioning as those created on the new, higher level.
