Pseudoaneurysm
Pseudoaneurysm
Pseudoaneurysm (pronounced: soo-doh-an-yuh-riz-uhm), also known as a false aneurysm, is a pathological dilation of an artery that occurs when blood leaks out of the artery and forms a sac-like structure adjacent to the artery. The term "pseudoaneurysm" is derived from the Greek words "pseudes" (false) and "aneurysma" (dilation).
Causes
A pseudoaneurysm can be caused by trauma, infection, or as a complication of medical procedures such as catheterization or surgery. It can also occur as a result of diseases that weaken the arterial wall, such as atherosclerosis or vasculitis.
Symptoms
Symptoms of a pseudoaneurysm can vary depending on its size and location. They may include pain, swelling, a pulsating mass, or, in severe cases, signs of hemorrhage or shock.
Diagnosis
Diagnosis of a pseudoaneurysm typically involves imaging studies such as ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI).
Treatment
Treatment options for a pseudoaneurysm depend on its size, location, and the patient's overall health. They may include observation, endovascular repair, or surgery.
