A pseudoaneurysm occurs when there is injury to an artery. The injury allows blood to leak out of the artery. The leaking blood collects or pools and is contained in the nearby tissues.
CAUSES
The most common cause of this condition is a procedure that involves inserting a thin tube (catheter) into an artery, such as an angiogram. After an angiogram, if the insertion site does not fully seal, blood may leak out of the artery. Other causes include:
• Trauma to the walls of an artery.
• Bypass artery grafting surgery.
• An infection affecting the walls of an artery.
• A heart attack (myocardial infarction).
• The rupture of an aneurysm.
SYMPTOMS
Symptoms of this condition include:
• Pain, discomfort, or tenderness
