Angiojet thrombus clearance device in hemodialysis access thrombosis / 中华普通外科杂志

ABSTRACT

Objective:To evaluate the role of Angiojet thrombus clearance device in the treatment of dialysis access thrombosis.Methods:The clinical data of 37 patients with Angiojet thrombus clearance due to hemodialysis thrombosis from May 2019 to May 2021 were retrospectively analyzed.Results:The clinical success rate was 100%, the mean operation time was (42±21) minutes. The time of aspiration was (35±18) s, and the average length of occlusion was (8±5) cm. All patients were treated with balloon dilation after aspiration. The average postoperative dialysis flow was (270±15) ml/min. The mean length of stay was (2.0±1.5) days. There were no surgically related deaths, no vascular rupture or bleeding, no major complications. Dilated local pseudoaneurysm formation was observed in 5 patients after dilation by angiography without special treatment. The mean follow-up time was 11 months. The primary patency rate was 85% and the secondary patency rate was 87% at 6 months post operatively.Conclusion:Angiojet thrombus removal device has the advantages of minimally invasive, short operation time and repeatability.
