Key result
Extensive surgical repair successfully treats acute type A aortic dissection complicated by cerebral malperfusion.
Why the study?
Cerebral malperfusion complicating acute type A aortic dissection carries high morbidity and mortality, and early cannulation with extended replacement of occluded or dissected carotid arteries remains an underused strategy.
Case Report (n=1)
Early cannulation and extended surgical replacement/bypass of occluded or dissected carotid arteries alongside comprehensive aortic repair can successfully treat cerebral malperfusion complicating acute type A aortic dissection.

Extended repair may be feasible for cerebral malperfusion in type A dissection; leaves open validation in larger cohorts.
Cerebral malperfusion complicating acute aortic dissection type A is a serious complication associated with markedly increased morbidity, permanent neurological deficit, and mortality. Early cannulation and extended replacement of occluded or dissected carotid arteries is an effective yet underused strategy for improving outcomes in such patients. We present a case of acute aortic dissection type A extending from the aortic root to the right common femoral artery, complicated by an occluded right common carotid artery and a dissected left common carotid artery. The patient was successfully treated with an extensive repair comprising David's procedure, arch repair, frozen elephant trunk implantation, bilateral extended carotid artery bypass and extended left subclavian artery bypass.

Meinert et al. (2026) conducted a case report in Acute aortic dissection type A complicated by cerebral malperfusion (occluded right common carotid artery and dissected left common carotid artery) (n=1). Extensive surgical repair including David's procedure, arch repair, frozen elephant trunk implantation, bilateral extended carotid artery bypass, and extended left subclavian artery bypass with supraclavicular subclavian artery cannulation was evaluated on Successful surgical treatment and resolution of cerebral malperfusion. Extensive surgical repair including David's procedure, arch repair, frozen elephant trunk, and bilateral carotid and left subclavian bypass successfully treated 1 patient with acute type A dissection.
