Juxtaanastomotic venous aneurysm in arteriovenous fistula for hemodialysis

Abstract

Introduction: Despite the great technical advance represented by internal arterio-venous fistulas for hemodialysis, these are not exempt from complications that compromise their durability. Among them are juxtaanastomotic venous aneurysms.

Objective: Present the surgical treatment used to repair juxtaanastomotic venous aneurysms.

Case presentation: 54-year-old patient, female and black skin color. She presented a history of chronic renal failure of 12 years of evolution, with failed kidney transplant, which had a juxtaanastomotic venous aneurysm, located in a humerus-cephalic arterio-venous fistula in the left upper limb, which was confirmed by Doppler echo. Aneurysmectomy and replacement grafting with expandable polytetrafluorethylene vascular prostheses were used as surgical treatment. Finally, the arterio-venous fistula was preserved, as well as its permeability.

Conclusions: The evolution was satisfactory in terms of durability and use as an access route for hemodialysis.
