Creation of arteriovenous fistula for hemodialysis in the older population

Abstract

Objective. To evaluate the results of arteriovenous fistula (AVF) created for haemodialysis in patients older than 65 years of age. Subjects and Methods. A retrospective analysis of patients with AVF or arteriovenous graft (AVG) creation, who were older than 65 years of age and were operated on at the II. Surgical Clinic at the University Hospital in Olomouc from 2014 - 2018 was performed. Results. 212 patients were evaluated and a total of 239 AVF/AVG were created. 194 AVFs (81.18%) and 45 AVGs (18.82%) were created. Primary failure was seen in 19 arteriovenous fistulas (9.8%) and 2 arteriovenous grafts (4.44%). The primary patency of AVF was 69.9%, 62.8% after 12 and 24 months, respectively, and in the case of AVG it was 54.7% and 32.3% after 12 and 24 months, respectively. Primarily assisted patency of AVF was 77.6% and 66.3% after 12 and 24 months, respectively, and in case of AVG it was 69.1% and 39.7% after 12 and 24 months, respectively. Secondary patency of AVF was 77.6% and 66.3% after 12 and 24 months, respectively, and for AVG it was 69.1% and 39.7% after 12 and 24 months, respectively. Conclusion. The type of vascular access should be selected based on a thorough, protocol-based examination. In most seniors, AVF is the method of choice. The AVG is a suitable choice for patients with an exhausted venous bed, in acute need of haemodialysis, in the elderly and in females. A "customized" approach should be matter of fact for older generations.
