Insights
This case study demonstrates successful complete supra-aortic revascularization in a patient with complex atherosclerosis. A novel bypass technique ensured safe bilateral carotid artery revascularization, preventing neurological complications.
Area of Science:
- Vascular Surgery
- Cardiovascular Disease
- Neurological Protection
Background:
- Atherosclerosis commonly affects multiple arteries, complicating surgical interventions.
- Complete supra-aortic artery involvement presents significant challenges for cerebral revascularization.
Abstract:
Atherosclerosis is a systemic disease, and multiarterial involvement is common. Involvement of all the supra-aortic arteries may occur in the same patient making cerebral revascularization challenging. In this report, we present complete supra-aortic revascularization, that is, revascularization of the bilateral common carotid and subclavian arteries in a 51-year-old male patient with occluded brachiocephalic trunk, left subclavian artery, and proximally stenotic left common carotid artery. A temporary ascending aorta to left external carotid artery bypass provided meticulous cerebral protection with pulsatile cerebral flow in the presence of a proximal arterial clamp; hence, a neurologically uneventful procedure during bilateral common carotid artery revascularization.
