Combined Stroke and Spinal Cord Ischemia in Hybrid Type I Aortic Arch Debranching and TEVAR and the Dual Role of the Left Subclavian Artery

Abstract

AORTIC ARCH PATHOLOGY, as a part of acute aortic syndrome, is a difficult clinical problem to address. Whether it presents as an intramural hematoma with impending rupture, isolated aneurysmal disease, or acute localized dissection, it creates a clinical challenge to the perioperative team. Some of the difficulty stems from determining the best operative strategy, either an open approach, total endovascular repair, or a hybrid of the two. Hybrid aortic arch repair involves two steps: open aortic branch revascularization and endovascular aortic repair. 1 Gregory AJ Prusinkiewicz CA Herget E et al.
