Interventional Radiologists Treat Abdominal Aneurysms Nonsurgically
Interventional radiologists are vascular experts who offer minimally invasive treatment for abdominal aortic aneurysm. An aortic aneurysm is a weak area in the aorta, the main blood vessel that carries blood from the heart to the rest of the body. As blood flows through the aorta, the weak area bulges like a balloon and can burst if the balloon gets too big.
In the past 30 years, the occurrence of Abdominal Aortic Aneurysms (AAA) has increased threefold. AAA is caused by a weakened area in the main vessel that supplies blood from the heart to the rest of the body. When blood flows through the aorta, the pressure of the blood beats against the weakened wall, which then bulges like a balloon. If the balloon grows large enough, there is a danger that it will burst. Most commonly, aortic aneurysms occur in the portion of the vessel below the renal artery origins. The aneurysm may extend into the vessels supplying the hips and pelvis.
Once an aneurysm reaches 5 cm in diameter, it is usually considered necessary to treat to prevent rupture. Below 5cm, the risk of the aneurysm rupturing is lower than the risk of conventional surgery in patients with normal surgical risks. The goal of therapy for aneurysms is to prevent them from rupturing. Once an abdominal aortic aneurysm has ruptured, the chances of survival are low, with 80 to 90 percent of all ruptured aneurysms resulting in death. These deaths can be avoided if an aneurysm is detected and treated before it ruptures.
Through its national screening program, Legs For Life, the Society of Interventional Radiology (SIR) has offered free screening for early detection and monitoring of AAA and other vascular diseases. Of those screened, 25 percent have been found to be at risk for AAA.
