Purpose:
To assess the safety and efficacy of the Arrow-Trerotola percutaneous thrombectomy device in the treatment of thrombosed hemodialysis access grafts in dialysis patients.
Materials And Methods:
Ten patients with graft fistula occlusion underwent mechanical thrombectomy with Arrow-Trerotola percutaneous thrombectomy device. Thirteen thrombectomy procedures were performed in ten patients. Technical success, complications, primary and secondary patency rates were noted.
Results:
The technical success rate was 84% (11 of 13 procedures). There were no major complications. The mean follow-up period was 8.5 months. The graft fistula are still functional in seven patients. In 3 of 7 patients, additional procedures were needed for patency. The 3-month primary and secondary patency rates were 66% and 77% respectively.
Conclusion:
Percutaneous mechanical thrombectomy with the Arrow-Trerotola device is an effective method for the treatment of the thrombosed hemodialysis grafts.
