Background: Arteriovenous (AV) fistula is the first choice of a long-term vascular access for hemodialysis, but there is a 20-30% probability of thrombosis in the 1 st month after its creation. Ticlopidine is a potent drug, which inhibits both primary and secondary platelet aggregation. This study is performed to evaluate the effect of ticlopidine in the prevention of AV fistula.

Methods: Totally 124 patients in need of an AV fistula were divided into two groups after creation of their fistula. In the first group, we prescribed ticlopidine for 62 patients, and in the second group, 62 patients received placebo. The two groups were compared to see if their fistulas are patent or thrombotic after 1 and 3 months.

Results: Of the 62 patients who received ticlopidine, four had fistula thrombosis, while in 62 patients who received placebo, 16 had fistula thrombosis (P= 0.003). This shows the significant effect of ticlopidine in the prevention of thrombosis in AV fistulas. Also, we compared age, sex, and the fistula location in the ticlopidine and placebo groups, and these attributes had no significant difference between the two groups (P> 0.050).

Conclusions: Considering the significant value of ticlopidine in the prevention of AV fistula thrombosis, it can be recommended after the surgery if there is no contraindication for its use.
