pseudoaneurysm
Sign in to saveAlso known as Aneurysm, False, false aneurysm
A pseudoaneurysm, also known as a false aneurysm, is a locally contained hematoma outside an artery or the heart due to damage to the vessel wall. The injury passes through all three layers of the arterial wall, causing a leak, which is contained by a new, weak "wall" formed by the products of the clotting cascade. A pseudoaneurysm (PSA) does not contain any layer of the vessel wall.

A pseudoaneurysm, also known as a false aneurysm, is a locally contained hematoma outside an artery or the heart due to damage to the vessel wall. The injury passes through all three layers of the arterial wall, causing a leak, which is contained by a new, weak "wall" formed by the products of the clotting cascade. A pseudoaneurysm (PSA) does not contain any layer of the vessel wall.
This differentiates it from a true aneurysm, which is contained by all three layers of the vessel wall, and a dissecting aneurysm, which has a breach in the innermost layer of an artery and subsequent dissection/separation of the tunica intima from the tunica media.
