Successful recanalization of acute superior mesenteric artery thrombotic occlusion with primary aspiration thrombectomy

Figure 1 Successful treatment of focal thrombotic occlusion on mid-trunk of superior mesenteric artery with primary aspiration thrombectomy and additional stent implantation. A: Superior mesenteric artery (SMA) angiography showing acute thromboembolism in the mid-trunk of SMA and the origin of jejunal and colic branches (arrows); B: Completely resolved thrombi and focal severe stenosis in the mid-portion of SMA main stem which was considered the leading cause of thromboembolism (arrow) after repetitive primary aspiration thrombectomy using a 6F aspiration catheter; C: A markedly improved stenosis and luminal blood flow of SMA without residual or migrated thrombi after implantation of a 6 mm x 18 mm balloon expandable stent (arrow).

Figure 2 Successful treatment of segmental complete thrombotic occlusion on mid-trunk of superior mesenteric artery with primary aspiration thrombectomy. A: Superior mesenteric artery (SMA) arteriography showing a complete thrombotic occlusion of the mid-portion of the main stem and the origin of ileocolic and right colic branches of SMA due to a large amount of thromboembolism (arrows); B: Complete removal of thromboembolism in the main stem of SMA but an intraluminal filling defect and flow occlusion at the distal portion of jejunal branch of SMA due to migrated thrombi during the procedure (arrows) after multiple courses of aspiration thrombectomy with a 6F aspiration catheter; C: A completely recanalized main stem and jejunal branch of SMA.
