Pseudoaneurysm

WHAT YOU NEED TO KNOW:

A pseudoaneurysm, or false aneurysm, is swelling of the wall of the artery. The swelling is caused by a small hole that has not sealed. A pseudoaneurysm can happen in any artery. It may become a medical emergency because the pseudoaneurysm can rupture.

WHILE YOU ARE HERE:

Informed consent

is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.

An IV

is a small tube placed in your vein that is used to give you medicine or liquids.

Antibiotics

may be given to prevent or treat a bacterial infection.

Tests:

  • Blood tests may be used to check how much your blood coagulates (forms a clot to stop bleeding).
  • An ultrasound may be used to check the size of the pseudoaneurysm, or to check if it ruptured.

Treatment:

  • Debridement is a procedure used to remove dead tissue. You may need this if the area around your pseudoaneurysm becomes infected.
  • Compression is a procedure that may be used if the pseudoaneurysm is in your leg. Your healthcare provider will place a device over the pseudoaneurysm and apply pressure. He may hold the pressure for 10 to 15 minutes. You may need to have this procedure a few times.
  • Medicine called thrombin may be injected into the sac to help seal the leak. You may need an arterial duplex scan 24 hours after the injection. An arterial duplex scan is an ultrasound used to check inside arteries. The scan helps make sure the leak is sealed and the injection did not cause artery damage.
  • Surgery may be used to repair the leak. Your healthcare provider may stitch the artery leak closed, or he may place a patch to seal it. He may need to bypass the artery (direct blood so it does not flow into the artery).

RISKS:

You may develop necrosis (tissue death) in the skin and tissue around the pseudoaneurysm. A ruptured pseudoaneurysm can cause severe bleeding.
