Pseudoaneurysm

Pseudoaneurysm

A Pseudoaneurysm or false aneurysm is a hematoma that forms as the result of a leaking hole in an artery. Unlike a true aneurysm, which involves a dilation of all three layers of an artery, a pseudoaneurysm occurs when blood escapes from an artery into the surrounding tissue but is confined next to the artery to form a blood-filled sac.

Causes

Pseudoaneurysms can be caused by trauma that punctures the artery, such as a stab wound, or by damage to the artery from a catheter or a surgical procedure. They can also occur as a complication of infections that erode arterial walls.

Symptoms

Symptoms of a pseudoaneurysm can include a pulsating bulge near the site of the injury, pain, and swelling. If the pseudoaneurysm ruptures, it can cause internal bleeding.

Diagnosis

Diagnosis of a pseudoaneurysm can be made through various methods, including a physical examination, ultrasound, CT scan, or MRI. An angiogram can also be used to visualize the blood vessels and detect a pseudoaneurysm.

Treatment

Treatment options for a pseudoaneurysm depend on its size, location, and the patient's overall health. They can include watchful waiting, medication to lower blood pressure, or surgery. In some cases, a procedure called thrombin injection can be used to clot the blood and seal the pseudoaneurysm.
