When a weak area of the abdominal aorta expands or bulges, it is called an Abdominal Aortic Aneurysm (AAA). The pressure from blood flowing through the abdominal aorta can cause a weakened part of the aorta to bulge, much like a balloon. A normal aorta is about 1 inch (or about 2 centimetres) in diameter; however, an AAA can stretch the aorta beyond its safety margin as it expands.
An AAA can also cause a problem called embolization. Clots or debris can form inside the aneurysm and travel to blood vessels leading to other organs in the body. If one of these blood vessels becomes blocked, it can cause severe pain or more serious problems such as limb loss.
AAAs are often silent and discovered incidentally during investigations for other conditions, making screening important for those at risk. Men aged over 65 are at highest risk. Ultrasound is an accurate and widely available screening tool.
Monitoring and Treatment
Smaller aneurysms are monitored with regular ultrasound or CT scans to track their size and rate of growth. Repair is recommended when the aneurysm reaches approximately 5.5 cm in diameter or is growing rapidly. Two main approaches are available: open surgical repair (involving replacement of the aneurysm with a synthetic graft through an abdominal incision) and endovascular repair (EVAR), which uses a stent-graft delivered through small incisions in the groin to seal the aneurysm from within. Dr Garbowski will discuss which approach is most appropriate based on the individual anatomy and fitness of the patient.

Endovascular Aortic Aneurysm Repair (EVAR/FEVAR/BEVAR)
EVAR, FEVAR and BEVAR are minimally invasive techniques for repairing aortic aneurysms using a stent-graft delivered through small incisions in the groin. They offer shorter hospital stays and faster recovery compared to traditional open surgery.
Frequently Asked Questions
An abdominal aortic aneurysm (AAA) is an abnormal bulging of the aorta in the abdomen. The aorta is the main artery carrying blood from the heart, and when its wall weakens, it can expand significantly. AAAs are often symptomless and discovered incidentally during scans for other conditions.
