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.

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

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.

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 myocardial infarction.

ymptoms

Pseudoaneurysm was linked to symptoms of cluster headache by Adam Koenigsberg MD and Glen Solomon MD in a well-described case report published in the Journal of Headache.cite journal |author=Koenigsberg AD, Solomon GD, Kosmorsky G |title=Psuedoaneurysm within the cavernous sinus presenting as cluster headache |journal=Headache |volume=34 |issue=2 |pages=111–3 |year=1994 |month=February |pmid=8163366 |doi= |url=]

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.
