# AORTIC
CONDITIONS

The aorta is the body's largest artery. It carries blood from your heart, down through your chest and abdomen, then splits low down into two branches (the iliac arteries) that supply each leg.

## Aortic Aneurysm & Aorta-iliac Disease

There are two main problems that affect the aorta. Vascular surgeon Dr Gregory Weir diagnoses and treats both in Pretoria, using open surgery and minimally invasive keyhole (endovascular) techniques. Select the area that concerns you to learn more.

### Aortic Aneurysm (AAA)

A weak, bulging section of the aorta – like a balloon – that can grow and, if left untreated, burst. Learn about screening, watchful waiting, open repair and keyhole repair (EVAR).

### Aorta-iliac Occlusive Disease

Narrowing or blockage of the aorta and iliac arteries that reduces blood flow to the legs, causing pain on walking. Learn about the symptoms, tests and treatment options.
