AngioJet Ultra thrombectomy for the treatment of limb endovascular aortic graft occlusion / 中华普通外科杂志

ABSTRACT

Objective:To assess the value of AngioJet Ultra thrombectomy device in dealing with limb graft occlusion after endovascular repair for abdominal aortic aneurysm.Methods:The clinical data of 12 unilateral limb graft occlusion cases treated with percutaneous mechanical thrombectomy (PMT) after endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) from Dec 2014 to Nov 2019 was retrospectively analyzed.Results:All 12 patients were male, age ranging from (63±12) years old.Four cases had left iliac limb graft occlusion and eight cases had right iliac limb graft occlusion. All cases were treated with PMT and iliac branch angioplasty. Successful rate was 100%.Nine cases with bifurcated stent-graft were then implanted bare/covered stent. Postoperative intermittent claudication/ gluteus claudication disappeared. Hemoglobinuria occurred in 2 cases after operation, in which one suffered from mild renal impairment and recovered. Median following-up time was 18 months, there was no recurrence of lower limb ischemia.Conclusion:Application of AngioJet Ultra thrombectomy device in PMT treatment was safe, effective and less traumatic for iliac limb graft occlusion after endovascular anortic repair for abdominal aortic aneurysm.
