Abstract

We present a case of tandem stenosis of the great vessels (cervical internal carotid artery [ICA] and brachiocephalic trunk ostium [BTO]) treated with stenting and balloon angioplasty of both lesions under flow arrest. A 70-yr-old woman with a history of hypertension, hyperlipidemia, coronary artery disease, and previous strokes presented with recurrent transient ischemic attacks of the left upper and lower extremities over the last 6 mo. She underwent right cervical endarterectomy (CEA) 16 yr prior. Neurological examination was unremarkable. Carotid Doppler ultrasonography revealed severely increased velocities of the right ICA. Cervical magnetic resonance angiography demonstrated 80% right ICA stenosis and 50% BTO stenosis. Digital subtraction cerebral angiography showed 80% right ICA stenosis and 70% BTO stenosis. The patient was not a candidate for standard carotid artery stenting because the BTO precluded endovascular access or for CEA because of the previous CEA; therefore, direct carotid access and flow reversal was an alternative. Under general anesthesia and systemic heparinization, the patient underwent right carotid artery surgical exposure. Under flow reversal using the Enroute System (Silk Road Medical, Sunnyvale, ...Continue Reading
