Abstract
BACKGROUND: Aortoiliac artery stenting has been accepted as the preferred option for the treatment of aortoiliac artery disease because of lower morbidity and mortality compared with bypass surgery. However, acute stent occlusion is a troublesome complication due to the need for open surgery or the risk of distal embolization. Herein, we reported a novel approach to treat the acute thrombotic occlusion of an aortoiliac stent using both hemolytic and conventional mechanical thrombectomy coupled with a large diameter sheath. CASE SUMMARY: A 64-year-old male patient presented with severe claudication of the right leg. The patient's history included multiple prior interventions for aortoiliac lesions. The preoperative computed tomography (CT) imaging showed a thrombotic occlusion of right aortoiliac stenting. An Angiojet Omni thrombectomy catheter (Boston Scientific, Marlborough, MA, United States) was used to remove the thrombus in a retrograde fashion after the successful placement of the large-diameter sheath in the right common femoral artery for prevention of distal embolization. The remnant organized thrombus was removed with an over-the-wire Fogarty catheter (Edwards Lifesciences, Irvine, CA, United States). Completion angiogram and postoperative CT imaging demonstrated complete removal of thrombus and no evidence of distal embolization. CONCLUSION: This novel approach provides successful management of acute thrombotic occlusion of aortoiliac stent without distal embolization.
