Surgery is generally recommended. The timing and indications for surgery differ depending on the type of aneurysm.

Some people are candidates for stent placement. This procedure involves the use of a tube placed inside the vessel and can be performed without an incision, with specialized catheters that are introduced through arteries at the groin. Not all patients with aneurysms are candidates for stenting, however.

With successful surgical repair, the outlook is often excellent.

The main complications of aneurysm include rupture, infection, and compression of local structures. Rupture of some types of aneurysms can cause massive bleeding, which is often fatal. This is commonly seen with abdominal aortic aneurysms, mesenteric artery aneurysms, and splenic artery aneurysms.

Rupture of aneurysms in the brain can cause stroke, disability, and death. Brain surgery for aneurysms can also result in these complications, if the aneurysm ruptures during surgery and bleeding cannot be controlled.

Infection of the aneurysm, which sometimes follows infection at other sites of the body, can lead to systemic illness and rupture. Clotting of the aneurysm occurs when blood stops moving inside the aneurysm, blocking further blood flow past the site of the aneurysm and depriving tissues beyond this of blood supply.

In certain cases, aneurysms can compress neighboring structures such as nerves, leading to neurologic problems, such as weakness and numbness. This can occur with popliteal artery aneurysms.

Call your physician for if you develop any new mass on your body, whether or not it is throbbing.
