The feasibility of endovascular re-canalization has been reported in a recent article. In the present report, we describe a 77-year-old man who received endovascular re-canalization of right ICAO. His clinical symptoms recurred 4 months after the procedure, and follow-up perfusion computed tomography (CT) revealed right hemisphere ischemia. Repeat carotid angiogram showed a large pseudo-aneurysm with narrowed true lumen in the distal cervical carotid artery, most likely resulted from previous re-canalization procedure. A coronary stent was deployed to re-establish patency of the vessel, covering and jailing the orifice of the pseudo-aneurysm. Late pseudo-aneurysm formation should be considered as a potential complication after endovascular re-canalization of ICAO.[SDGs]SDG3aged; article; brain ischemia; carotid arteriography; case report; computer assisted tomography; coronary stent; disease association; endovascular surgery; false aneurysm; follow up; human; internal carotid artery occlusion; male; perfusion; recanalization; recurrent disease; right hemisphere; vascular patencyjournal article2-s2.0-36549074254
