Aneurysms

Miami Cardiac & Vascular Institute has expertise in the diagnosis and treatment of:

  • Abdominal aortic aneurysms, or AAAs (located in the abdominal portion of the aorta, the largest artery in the body, which carries oxygenated blood from the heart)
  • Thoracic aortic aneurysms (the short section of the aorta in the chest cavity)
  • Peripheral aneurysms (legs)
  • Cerebral aneurysms (brain)

Our physicians work with you to help you manage and treat the disease before it has serious consequences. Our goal is to improve your health and quality of life.


Aneurysm Treatment Options

If you have a small aortic aneurysm, you may not require immediate treatment because this type rarely ruptures. Instead, we may recommend “watchful waiting” and regular ultrasound exams to check for changes.

Institute surgeons can repair other aneurysms using open AAA surgery. You might also be a candidate for minimally invasive endovascular repair (known as EVAR). During EVAR, a physician threads a device called a stent-graft through a blood vessel in your groin and into your aorta. Blood flows through the stent-graft, preventing pressure on the aneurysm and causing it to shrink.

In 1994, Miami Cardiac & Vascular Institute became one of America’s first five medical centers to participate in research trials using stent-grafts to treat AAAs. Institute physicians continue to participate in the latest trials for abdominal aortic and thoracic aneurysms.

Patients with thoracic and peripheral aneurysms also can be treated with open surgery or endovascular repair. Treatments for cerebral aneurysms include endovascular coiling and flow-diverting embolization.

The Institute’s endovascular team has performed endovascular repair of nearly 1,000 abdominal aortic and thoracic aneurysms with excellent results. Their work is aided by the Institute’s endovascular suite, which is one of the most advanced in the world.

The care team at Miami Cardiac & Vascular Institute encourages all patients and family members to learn more about conditions and diseases that affect the heart and overall cardiovascular system. The links below provide more information about heart conditions and diseases that might be treated within this program.

Abdominal Aortic Aneurysm
An aneurysm is a bulging, weakened area in the wall of a blood vessel resulting in an abnormal widening or ballooning greater than 50 percent of the vessel's normal diameter (width). An aneurysm may occur in any blood vessel, but is most often seen in an artery rather than a vein.

Cerebral Aneurysm
A cerebral aneurysm (also called an intracranial aneurysm or brain aneurysm) is a bulging, weakened area in the wall of an artery in the brain, resulting in an abnormal widening, ballooning, or bleb. Because there is a weakened spot in the aneurysm wall, there is a risk for rupture (bursting) of the aneurysm.

Thoracic Aortic Aneurysm
A thoracic aortic aneurysm, also called TAA, is a bulging, weakened area in the wall of the aorta (the largest artery in the body), resulting in an abnormal widening or ballooning greater than 50 percent of the vessel's normal diameter (width).​

To help in the diagnosis of an aneurysm, your physician may request that you have one or more of the following tests:

  • CT scan
  • MRI
  • Magnetic resonance angiogram (MRA)
  • Echocardiogram
  • Ultrasound examination
