Transluminal angioplasty versus surgical repair for stenosis of hemodialysis grafts. A randomized study.

ABSTRACT

A randomized study of transluminal angioplasty versus surgical revision for stenosis at the venous end of hemodialysis grafts was carried out. Median patency for the surgical group was 12 months versus only 4 months for the transluminal angioplasty group. This difference was statistically significant (p less than 0.01). In addition, the average cost for surgical revision was slightly less than that for transluminal angioplasty. Therefore, for long-term patency, surgical treatment is the method of choice, although under special circumstances there may still be a role for transluminal angioplasty.
