MeSH	D017541

A pseudoaneurysm, also known as a false aneurysm, is the result of trauma to all three layers of an artery resulting in a hematoma that contains the bleed. This hematoma must continue to communicate with the artery to be considered a pseudoaneurysm. A pseudoaneurysm differs from a true aneurysm in that a pseudoaneurysm does not contain any of the vessel wall Media:http://www.myelectronicmd.com/get_reference.php?Id=1164 Media:http://www.cvtcollege.org/Ac_Programs/dms_vascular/studentbrandie.html.

Femoral pseudoaneurysms may complicate up to 8% of vascular interventional procedures. Small pseudoaneurysms can spontaneously clot, while others need definitive treatment.

[edit] Treatment

Surgery is considered the gold-standard treatment, although not without risk in patients with severe cardiovascular disease.

Less invasive treatment options, such as Duplex ultrasound-guided compression and percutaneous thrombin injection are available, however, evidence of their efficacy is somewhat limited.

[edit] Association with trauma

A pseudoaneurysm may also occur in a chamber of the heart following myocardial damage due to ischemia or trauma. An pseudoaneurysm of the left ventricle is a potentially lethal complication from a heart attack. After a heart attack, the left ventricular wall of the heart, may rupture.

[edit] Locations

Although aneurysms and left ventricular aneurysms may involve any wall segment, aneurysms in the posterolateral wall are frequently due to pseudoaneurysms. In contrast, the most common location for a true left ventricular aneurysm involves the apex of the heart.
