Pseudo-Aneurysm: Care Instructions

Your Care Instructions

A pseudo-aneurysm is a hole in the wall of a blood vessel (artery). The blood from inside the artery can then leak out of the artery. It is most common in the artery that runs from the hip to the knee. It can be caused by the puncture of an artery during a medical test, such as certain heart tests. People who take blood thinners are more likely to develop a pseudo-aneurysm.

Some pseudo-aneurysms heal without treatment. Those that continue to grow larger may need treatment. The doctor may inject medicine through a needle to make the blood clot in the pseudo-aneurysm. He or she may also use pressure (compression) to make the blood clot. If these do not work, you may need surgery to repair the hole in the artery.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
