Pseudoaneurysm

A pseudoaneurysm is a condition that is also known as a false aneurysm. A pseudoaneurysm happens when blood leaks through a rupture in the vessel wall but is contained by the adventitia or surrounding perivascular soft tissue. A direct transmission of blood flow exists between the vessel lumen and the aneurysm lumen through the hole in the vessel wall. The risk of rupture is higher with a pseudoaneurysm than with that of a true aneurysm of comparable size, due to poor support of the aneurysm wall. Pseudoaneurysms generally require treatment.

Pseudoaneurysm Symptoms

The symptoms of a pseudoaneurysm are usually a painful, tender, pulsatile mass, and the overlying skin is sometimes red. These pulsatile masses can sometimes be confused with abscesses. A person who is experiencing these symptoms may describe a history of catheterization or trauma, and they may note the gradual expansion of the pulsatile mass.
