Abstract

 

Aim: The patients with chronic renal failure need Arteriovenous (AV) fistulas that are long term patency for hemodialysis. The aim of this study is to identify at the early and late stages of the complications after AV fistulas operations.

Materials and Methods: This study was performed retrospectively at the clinic of cardiovascular surgery between October 2009 and February 2011 and contains 72 patients who had undergone AV fistula operation. Group 1 consisted of reintervention at the early stage (first 48 hours), and group 2 consisted of reintervention at the late stage (term following 48 hours).

Results: Thrombosis (n=11), bleeding (n=4) and hematoma (n=3) at the early stage developed in the group 1. At the late stage aneurysm (n=8), stenosis or thrombosis (n=11), overflow AV fistulas (n=5), peripheric ischemia (n=2) were developed in the group 2.

Conclusions: The morbidity and mortality of patients can be reduced by developing methods that improve the patency of AV fistula procedure and decrease the complications in patients with chronic renal failure.
