ANEURYSMS

What is an Aneurysm? An abnormal widening or ballooning of a portion of a blood vessel. The blood vessel wall becomes weaker in this location. Aneurysms can occur in any artery in the body.


Some common locations for aneurysms include:
  • Abdominal aortic aneurysm
  • Thoracic aortic aneurysm
  • Cerebral aneurysm
  • Popliteal artery (leg) aneurysm
  • Mesenteric artery (intestine) aneurysm
  • Splenic artery aneurysm

Aneurysms are either congenital or acquired. It is not clear exactly what causes aneurysms. In certain cases (abdominal aortic aneurysms), hypertension is thought to be a contributing factor.

Atherosclerotic disease (cholesterol buildup in arteries) may contribute to the formation of certain types of aneurysms. Pregnancy is often associated with the formation and/or rupture of splenic artery aneurysms.

What are the Symptoms of an Aneurysm?

Swelling with a pulsatile (throbbing) mass at the site of the aneurysm are often seen.

In the case of rupture, hypotension (low blood pressure), high heart rate, and lightheadedness are seen. The risk of death from rupture is high.

How are Aneurysms Diagnosed?

Physical exam, ultrasound examination, and CT scan are used to evaluate aneurysms.

How are Aneurysms Treated?

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