Early Experience with Spot Stenting for Native Arteriovenous Dialysis Fistula Stenosis with Multi-LOC Stent: A Single-Center Experience

 

Background: Assessment of patency rate of multi-LOC stent placement for arteriovenous dialysis fistula stenosis in our institution

Materials and Methods: This is a case series, single-center study of three patients conducted from January 2019 to February 2020. All patients presenting with recurrent AVF failure (thrombosis, stenosis or resistance stenosis, and insufficient angioplasty) who underwent endovascular treatment with multi-LOC stent were included.

Results: During 1-year study period, three patients (two males and one female) who have arteriovenous fistula dysfunction underwent multi-LOC stent procedure. The mean age was 69 years and the dialysis access was two brachiocephalic and one brachiobasilic. A total of nine stent segments were deployed (cephalic arch, two different anastomotic site 2, and six in juxta-anastomosis). One patient with multifocal stenosis (six stent segments) presented with fistula thrombosis at 109 days. The remaining two fistulas remain patent at 319 and 199 days of follow-up.

Conclusion: This is an early experience with multi-LOC spot stenting. This is preliminary data on the use multi-LOC stenting in dialysis access, further evaluation of this stent in this specific indication still required.
