Aortic Occlusive Disease

Find your care

Our specialists are experts in treating aortic disease. To learn more about our services, call 310-206-6294.

Aortic occlusive disease occurs when blood flow in the aorta is blocked. There are many different health conditions that can cause blockages in the aorta. Aortic occlusive disease can slow or block blood flow to the body’s major organs and cause a number of serious health issues. These include:

Arm or leg pain with use (called claudication) or at rest
Severe high blood pressure
Stroke
Abdominal pain when eating
Other symptoms of organ dysfunction

Causes of Aortic Occlusive Disease

Blockages in the aorta can be due to a variety of health conditions, including:

Atherosclerotic disease (plaque build up in the arteries)
Aortic dissection
Birth defects (congenital “narrowing” of the artery called coarctation)
Swelling from inflammatory conditions such as Takayasu arteritis

Symptoms of Aortic Occlusive Disease

The symptoms of aortic occlusive disease depend on the severity of the blockage and its location in the aorta. Symptoms can worsen depending on how much blood flow is restricted because of the blockage. Sometimes symptoms can arise quickly and be so severe that urgent medical treatment is necessary. Other times symptoms are mild enough that treatment can be delayed until further diagnostic tests determine the cause of the disease.

Symptoms can include:

Dizziness
Fainting
Erectile dysfunction in men
High blood pressure
Pain, fatigue, numbness in the arms
Pain, fatigue, numbness in the legs
Stroke
Transient ischemic attacks
Abdominal pain after eating leading to weight loss

Expert Diagnosis of Aortic Occlusive Disease at UCLA

At UCLA, we use a variety of methods to diagnose aortic occlusive disease. Often our doctors can make a diagnosis after a physical examination, but we also use advanced diagnostic imaging to pinpoint the exact location and assess the severity of a blockage in the aorta. The type of diagnostic test you will receive depends on your symptoms. These types of tests can include:

Duplex Ultrasonography
Ankle/ Brachial indices and segmental extremity pressures
Intravascular ultrasound
CTA (computed tomography angiography)
MRA (magnetic resonance angiography)

Advanced Treatment of Aortic Occlusive Disease at UCLA

At UCLA, we offer the most advanced treatments for aortic occlusive disease including minimally invasive endovascular surgeries and the latest medical therapies. Our team approach at the UCLA Aortic Center makes sure that you receive care for both your underlying medical condition and your aortic blockage. In many cases, medicine (such as blood thinners or anti-inflammatory medication) and surgery are both used as treatments.

If your aortic occlusive disease is caused by blood clot, our doctors use catheter-directed therapy in which a clot-dissolving drug is slowly infused into the clot over a several days. This procedure called thrombolysis allows for restoration of blood flow through the blocked artery without the need for major surgery.

In more advanced cases, less invasive endovascular intervention or surgery may be required to remove the blockage in the aorta.
