New Aneurysm Graft: Diffusing a Time Bomb -- Research Summary

BACKGROUND: An aneurysm is an abnormal bulge in the wall of an artery. Normally, the walls of arteries are thick and muscular, allowing them to withstand a large amount of pressure. Occasionally, a weak area develops in the wall of an artery. This allows the pressure within the artery to push outwards, creating a bulge or ballooned area called an "aneurysm." An abdominal aortic aneurysm is when the large blood vessel that supplies blood to the abdomen, pelvis, and legs becomes abnormally large or balloons outward.

SYMPTOMS: Abdominal aortic aneurysms often grow slowly and usually without symptoms, making them difficult to detect. As an aortic aneurysm enlarges, some people may notice:
• A pulsating feeling near the navel
• Tenderness or pain in the abdomen, back, or chest – severe, sudden, persistent, or constant. The pain may radiate to the groin, buttocks, or legs.
• Clammy skin
• Nausea and vomiting
• Rapid heart rate
• Shock

THINGS YOU DIDN’T KNOW: An abdominal aortic aneurysm can develop in anyone, but is most often seen in males over 60 who have one or more risk factors. The larger the aneurysm, the more likely it is to rupture and break open. (SOURCE: www.ncbi.nlm.nih.gov/pubmedhealth)


TREATMENT: If bleeding occurs inside the body from an aortic aneurysm, the abdominal aortic aneurysm has opened and needs repair. Surgery is usually recommended for patients who have aneurysms bigger than 2 inches (5.5 cm) across and aneurysms that are growing quickly. The goal is to perform surgery before complications or symptoms develop. In a traditional (open) repair, a large cut is made in the abdomen. The abnormal vessel is replaced with a graft made of man-made material, such as Dacron. (SOURCE: www.ncbi.nlm.nih.gov/pubmedhealth)


LATEST BREAKTHROUGHS: Another form of surgery is endovascular stent grafting. An endovascular stent graft is a tube composed of fabric supported by a metal mesh called a stent. The graft is stronger than the weakened artery and it allows your blood to pass through it without pushing on the bulge. This procedure can be done without making a large cut in the abdomen, making recovery time faster.  Endovascular repair is rarely done for a leaking or bleeding aneurysm. However, it is the safest approach when the patient is suffering from other medical conditions. MORE
