Outcomes of arteriovenous fistula for hemodialysis in octogenarian population

Abstract

Eighty-eight arteriovenous fistula constructions and six salvage procedures were performed in 70 octogenarians. Fifty-four (61.3%) forearm and 34 (38.7%) upper arm fistulas were created. All types of fistulas had 6-, 12-, 18-, and 24-month death-censored cumulative patency rates of 63.6%, 58.3%, 48.8%, and 41.4%, respectively. The primary failure rate was 40.9%. A total of 15 complications were documented as edema, hematoma/bleeding, infection, distal ischemia, and venous aneurysm, all of which had been treated. Patient survival rates for 12 and 24 months were 68.5% and 58.5%, respectively. This analysis regarding arteriovenous fistula in octogenarian end-stage renal disease patients figured out equal death-censored cumulative patency compared to nonelderly, and two-year survival rate was acceptable. This study strengthens the argument that arteriovenous fistula should be the best proper choice in selected octogenarians; older age only should not be considered as an absolute contraindication for arteriovenous fistula creation in octogenarians; and patient-based approach should be applied.
