Ischemic Stroke Caused by Carotid Stump at the Common Carotid Artery

An 84-year-old man developed motor aphasia and right hemiparesis on postoperative day 1 after orchiectomy for suspected malignant lymphoma. He had a history of thoracic endovascular aortic repair for aortic aneurysm using a bypass graft from the right subclavian artery to the left common carotid art...

Description
Summary:An 84-year-old man developed motor aphasia and right hemiparesis on postoperative day 1 after orchiectomy for suspected malignant lymphoma. He had a history of thoracic endovascular aortic repair for aortic aneurysm using a bypass graft from the right subclavian artery to the left common carotid artery (CCA); however, the graft had become occluded six months later. Brain magnetic resonance imaging revealed acute cerebral infarctions in the left frontal lobe. Carotid ultrasonography revealed a stump at the left CCA, just below the bifurcation, formed by the occluded graft with an oscillating thrombus. This case was rare in that a CCA stump was identified as the embolic source of ischemic stroke.
