Preferred Label : Dissection, Blood Vessel;
MeSH definition : A tear or separation of the layers by a blood vessel typically involving vessels under
pressure, i.e., ARTERIES, e.g., AORTA. Tearing of the TUNICA INTIMA layer of a blood
vessel may lead to interstitial HEMORRHAGE. Dissection between the tunica intima and
TUNICA MEDIA causes luminal occlusion. Dissection at the media, or between the media
and the outer ADVENTITIA causes aneurismal dilation.;
MeSH synonym : Blood Vessel Dissection;
MeSH hyponym : Arterial Dissections; Dissection, Arterial; Dissection Artery; Arteries, Dissection; Artery, Dissection; Dissection Arteries;
MeSH annotation : coordinate with specific aneurysm term if available; otherwise coordinate with specific
vessel or precoordinated vascular disease;
Origin ID : D000094665;
