The Effect of Endovascular Management of Arteriovenous Fistulae the Stenosis A Review of Local Experience: A Review of Local Experience

Abstract

The objective of this paper is to determine the success of Endovascular procedures (Percutaneous transluminal angioplasty) as an initial procedure to treat dialysis arteriovenous fistula (AVF) stenosis. There were fifty one patients who under­went fifty four vascular access surgeries from May 2009 to February 2011 at the Rangueil Hospital. They were retrospectively evaluated on the base of a duplex ultrasound study and insufficient hemodialysis. Among the fifty four vascular access surgeries, thirteen (24%) were documented as having arteriovenous fistula stenosis, and among them, seven patients (53.8% of the 13 patients) required percutaneous transluminal angioplasty (PTA) as an initial procedure for treatment. Among the accesses that were documented to have arteriovenous fistula stenosis, 71% of lesions were in the juxta-anastomotic area, while 29% were in the venous limb (draining limb). The results of the study revealed that the initial success rate of percutaneous transluminal angioplasty in the treatment of stenotic lesions was 86% of the cases and saved the vascular access site. In these patients, the post-intervention patency at one, three and six months was 86%, 85% and 66%, respectively. It can be concluded that this method is thus a promising form of semi-invasive treatment for sympto­matic arteriovenous fistula stenosis.
