Acute carotid stent thrombosis: A case report and literature review

Figure 1 Pre-operative imaging examination. A: Pre-operative computed tomography angioplasty (CTA) showed severe stenosis of right internal carotid artery; B: Aortic CTA showed infrarenal abdominal aortic aneurysm with maximum diameter of 53 mm.

Figure 2 The interventional procedure. A: The distal of the internal carotid artery (ICA) was obliterated; B: The ICA was patent with about 40% residual stenosis after the embolism protection device was retrieved; C: Angiography after endovascular aortic repair (EVAR); D: After EVAR, carotid angiography showed acute thrombus formation in the stent.

Figure 3 The carotid endarterectomy procedure. A: Plaque rupture and thrombus formation; B: The stent was occluded by the plaque debris and thrombus; C: Patch angioplasty was carried out during carotid endarterectomy (CEA); D: Angiography after CEA showed the internal carotid artery was patent.

Figure 4  Computed tomography angioplasty after 1 yr showed the internal carotid artery was patent without restenosis.
