Treatment for aortic aneurysm depends on the size of the aneurysm, its location and shape. If it’s a small aneurysm, usually regular ultrasound scans monitoring at intervals is all that is required. However when the size of aneurysm reaches 5.5cm and above, planned surgery is required before it bursts. Surgery can be done traditionally using big incisions and the dilated portion of the artery is replaced with artificial graft. With modern technology, it can also be treated with a customized stent to prevent bursting (EVAR). This is a fatal condition if left untreated but with planned surgery the risk can be as low as 1%.
