In the last five years, we have treated 58 thrombosed native arteriovenous fistulae for hemodialysis. In the 25 last fistulas, we have begun to exclusively use the technique of manual tromboaspiratión with catheter. The access have been 12 radial, 1 cubital and 12 brachial fistulas

The treated lesions (n=29) responsible for the thrombosis have been 5 perianastomotic stenosis, 4 distal estenosis to the anastomosis, 15 occlusions and 5 cases with trombotic material without underlying lesion. In all the cases except in one, we were able to make the thrombectomy (technical success 96 %). In 5 cases, we implanted stent. In 21 cases we saved the access for the dialysis (clinical success 84 %). The results have improved progressively, being in the last year a clinical success of 100 %. The cumulative patency at 6 and 12 months have been 68 and 32 % respectively. At the end of the follow-up, 15 fistulas (60 %) are functioning

According to these results, and comparing them with those of literature, we think that the technique of manual thromboaspiration with catheter is very effective for the radiological repair of the trombosed native vascular access of haemodialysis.

The thrombosed native fistulas for hemodialysis cannot be treated in the same form as grafts. The devices used habitually in these usually are not useful in the native access. The thrombectomy by manual aspiration with catheter in the native fistulas for hemodialysis is an effective and cheap technique
