Aortic arch repair today: open repair is best for most arch lesions

Abstract

The transverse aortic arch is challenging to repair by either evolving open or emerging endovascular approaches. Contemporary experience in aortic arch repair can be difficult to assess because clinical practice varies substantially among centers with regard to temperature targets for hypothermic circulatory arrest, temperature monitoring sites, circulating perfusate temperatures, cerebral perfusion monitoring techniques, perfusion catheter flow rates, cannulation sites, pH management, and protective pharmacologic agents. Repair of the aortic arch has changed substantially over the last decade; these changes appear to have substantially reduced patient risk. In general, contemporary outcomes of open aortic arch repair are good to excellent. When acute aortic dissection is absent, many centers report early mortality rates below 5%; when acute aortic dissection is present, these rates are doubled or tripled. Not unexpectedly, mortality rates for total transverse aortic arch repair with elephant trunk or frozen elephant trunk approaches are greater than those for hemiarch repair (7-17% vs. 3-4%). In contemporary reports of mixed hemiarch and total arch repairs for aortic aneurysm, several authors report early mortality rates and s...Continue Reading

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.

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
