    Aim: To compare the success rate, primary patency of thrombosed prosthetic vascular access grafts of the upper limb after thrombectomy and balloon dilatation of stenotic segments at venous anastomotic sites using either Paclitaxel-coated PTA balloon catheters or plain balloon PTA catheters. Patients & methods: Thirty seven (37) patients with thrombosed prosthetic vascular access PTFE grafts of the upper limb from October 2013 till February 2014, were randomized into two groups. After thrombectomy of the prosthetic graft, patients in group A underwent balloon dilatation of stenotic segment at venous anastomotic site using Paclitaxel-coated PTA balloon catheters, while in group B they were treated using plain balloon PTA catheters. Results: The success rate was 89.5% (n=17), 83.3%(n=15) in both groups respectively. The patency rate in 6 months was 82.4% for group A, while in group B it was 53.3%. After one year the patency rate was 58.8%. 33.3% for both groups respectively. Conclusion: Using Paclitaxel-coated PTA balloon catheters have higher patency rates in comparison to plain balloon catheters, but still these results are statistically insignificant may be due to small number of study sample. Key words: Venous anastomosis stenosis, Paclitaxel-coated PTA balloon, graft thrombectomy.
