Dissecting aneurysm

Dissecting aneurysm: A localized widening (dilatation) of an artery (an aneurysm) in which the wall of an artery rips (dissects) longitudinally. This occurs because bleeding into the weakened wall splits the wall. Dissecting aneurysms tend to affect the thoracic aorta. They are particularly a major danger in Marfan's disease.

Common Misspellings: dissecting anuerism, dissecting anerysm, dissecting aneuresym, dissecting aneuysm, dissecting anuerysm, dissecting anurism
