What Causes An Abdominal Aortic Aneurysm
Cysticmedialnecrosis: The aorta is a living organ. Has 3 layers. Intima, media, adventitia. The aortic wall is nourished by the vasa vasorum. Arteriosclerosis creates cholesterol plaque, the vasa vasorum occlude, the media slowly dies and becomes replaced by collagenous tissue, pressure and Collagenase activity weaken wall and it dilates excessively, if not repaired claims 17, 000 americans/yr.70%infrarenal. ...Read moreSee 2 more doctor answers
"Aneurysm" has scary implications for many people. It just means an enlargement of an artery. The problem is that when arteries (including the aorta) get too large, their walls become weak and prone to tear (dissection) or rupture. If this happens in the aorta it can be a catastrophe. Management of aortic aneurysms depends on where it is, how big, whether it's growing, ...Read more
Bulging Aorta: Ballooning of the abdominal portion of the aorta. The aorta is one of the major arteries that carry blood from your heart to the rest of the body. Sometimes patients with high blood pressure, cholesterol plaque formation can have weakened wall of this big artery, causing it to bulge ( balloon out) like when one blow air into a balloon; if ruptured, instant death can occur. ...Read moreSee 2 more doctor answers
Ballooning : An aneurysm is diffuse or focal dilatation of an artery like the abdominal aorta of more than 1.5 times its normal size. For abdominal aortic aneurysm generally anything above 3 cm in 50-60yr old patient. They typically don't need fixed unless above 5 cm in females and 5.5 cm in males or rapidly enlarging or causing symptoms. ...Read moreSee 2 more doctor answers
Lower part: Infra renal aneurysm means it is involving the lower part of the abdominal aorta after it gives rise to the blood vessels supplying the kidneys. Infra renal aneurysms can be generally treated with a stent graft which is implanted going through the artery in the groin. It is thus possible that a major surgery involving opening the abdomen can be avoided. ...Read moreSee 2 more doctor answers
No: Trauma such as falling does not cause aaas. They typically form slowly over time due to inflammation in the wall of the aorta. Risk factors are age >65, smoking, male gender and a family history. Interestingly high speed motor vehicle accidents can cause a tear in the thoracic aorta. These are called dissections. ...Read moreSee 2 more doctor answers
Size & location: This really depends on size of the aneurysm , the bigger one especially above 5-5.5 cm will have higher risk of rupture and death. Also location so if aneurysm involves major branches to brain or arteries to kidneys or intestinal arteries all this will make the surgical repair more risky. ...Read moreSee 1 more doctor answer

The repair of this type of aneurysm is very challenging and so be sure and see a board certified Vascular Surgeon with a great deal of experience for consultation and treatment. ...Read moreSee 3 more doctor answers
Ruptured aneurysm: An abdominal aneurysm can rupture for many reasons. Most common is size. As the aneurysm enlarges the wall gets weaker. We know that aneurysms over 5 cm have a higher rupture rate and those should be operated on electively. Other factors making rupture more likely would be uncontrolled high blood pressure and infection in the wall of aneiurysm. ...Read more
Several things: About 5% of men over the age of 65 have abdominal aortic aneurysms. Risk factors include: increasing age, male sex, family history of aneurysm (may increase your risk 4-fold), hypertension, and history of smoking. Dissecting aneurysms can be caused by localized damage to to the artery from hypertension or trauma (deceleration or sheering-type injury) or catheter injury from an angiogram. ...Read moreSee 2 more doctor answers
Weak wall: The aorta is a living pipe. It has 3 layers, the inner layer or intima, the middle layer or media were some muscle like cells dwell and the adventitia rich in collagen fibers. The process of arteriosclerosis may result in slow death of the media which then gets replaced by collagen scar. The pressure inside the aorta and the wall weakness will result in dilatation of the aorta and it could burst. ...Read moreSee 2 more doctor answers
With twists/bends: The term "tortuous" simply means: full of twists, turns and bends. In medicine we use this to describe the pathway of veins or arteries. When either veins or arteries "grow" to become varicose veins or aneurysms, not only do they grow in diameter, but also in length. As they grow longer, they start bending and twisting to accommodate and "fit" into the same body. ...Read moreSee 2 more doctor answers
Usually none: Most of AAA have no symptoms and discovered by routine physical exams, screening ultrasound or incidental finding on ct scans. If symptomatic then usually pain in upper to mid abdomen sometimes radiating to the back or just back pain , rupture with severe pain and shock , sometimes present as clots traveling to the legs with acute pain or blue toes. Rare type is infected or inflammatory /fever. ...Read moreSee 2 more doctor answers
AAA>5cm may rapture : Abdominal aortic aneurysm (AAA) is considered a surgical disease if it is > 5 cm. At that point the risk of rupture is greater then the risk of surgical complications. These days many cases are done via endovascular repair instead of open surgery. ...Read moreSee 2 more doctor answers
