Possible causes of aneurysm and pseudoaneurysm of the arteriovenous fistula in patients with renal failure. Rev Cubana Angiol Cir Vasc [online]. 2015, vol.16, n.2, pp.205-215. ISSN 1682-0037.

The ideal vascular access should provide adequate flow to meet dialysis requirements, should be long lasting and also have a low rate of complications. Autologous fistula is considered the first choice for vascular access in hemodialysis. If the causes of aneurysms and pseudoaneurysms of fistulae are well known, they are very unusual and so, it is important to know why they occur. Several cases of aneurysms and pseudoaneurysms of fistulae, their causes and how to prevent them were shown. Six cases with arteriovenous fistulae for hemodialysis were presented; the surgery was performed in "Victoria Mahe" Hospital in Seychelles islands in two years, the diagnosis was clinical and ultrasonographic. There were one elderly diabetic patient with pseudo-aneurysm in the artery of the fistula after ligation at the elbow, one with multiple venous aneurysms in a fistula of over 5 years of progression and four patients with vein pseudo-aneurysms due to fistula rupture. It is very important not only to make a vascular access for dialysis, but also to take care of it so as to avoid aneurysms and pseudoaneurysms. To this end, it is advisable to rotate the puncture sites, to severe hypotension, to educate patients about what should not be done with the fistula arm, to perform good aseptic- antiseptic actions before starting dialysis to prevent sepsis and other complications and to prepare nurses to conduct the procedure.

Keywords : vascular access; arteriovenous fistulas; arteriovenous fistula complications; aneurysms and pseudoaneurysms of arteriovenous fistulas.
