Abstract

Ascending aorta or hemi-arch repair are common in the acute phase of type A dissection. Postdissection aneurysms can develop with antegrade perfusion of the false lumen in the dissected aortic arch and require reoperation. From 2012 to 2018, we reoperated nine patients with postdissection aneurysms using a hybrid technique without cardiopulmonary bypass. The patients had a EuroSCORE II of 13% and a logistic EuroSCORE I of 45% and were not candidates for frozen elephant trunk surgery. The median interval since the acute ascending repair was 184 (92; 528) days. All patients were treated by median resternotomy, ascending to carotid bypass on a partially clamped ascending graft, and transfemoral endovascular repair with a Relay NBS (nonbare stent) or conformable Gore C-TAG stent graft. Technical success was achieved in all cases. Mean follow-up was 405 (220; 672) days. There was no disabling stroke, endoleak, paraplegia, in-hospital, or late mortality. In all patients, the false lumen was completely thrombosed at the aortic arch level with a median aneurysm shrinkage of 13 mm in the distal arch. There was no bird beak or stent graft migration. Distal stent-induced new entry was observed in one case. Reinterventions were not necessa...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
