False aneurysm

False Aneurysm

A False Aneurysm, also known as a pseudoaneurysm, is a pathological dilation of a blood vessel that occurs when blood leaks from the vessel and is contained by the surrounding tissues. This condition is different from a true aneurysm, where the dilation involves all three layers of the blood vessel wall.

Causes

False aneurysms can occur as a result of trauma, infection, or iatrogenic causes such as a complication of a catheterization procedure. They can also occur as a result of a vascular surgery or an endovascular procedure.

Symptoms

The symptoms of a false aneurysm can vary depending on its location and size. They may include pain, swelling, a pulsating mass, or, in some cases, no symptoms at all. If the false aneurysm ruptures, it can cause severe bleeding and potentially life-threatening complications.

Diagnosis

Diagnosis of a false aneurysm typically involves imaging studies such as ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI). These tests can help to visualize the structure of the blood vessels and identify any abnormalities.

Treatment

Treatment for a false aneurysm may involve surgery to repair the damaged blood vessel, or a less invasive procedure known as endovascular repair, which involves inserting a stent-graft into the blood vessel to seal off the aneurysm. In some cases, a false aneurysm may resolve on its own without treatment.
