What does a tortuous abdominal aortic aneurysm mean?

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.
Not straight. It may or may not be consequential. On the other hand, it may cause decrease in blood flow or have clot in it. So, tortuosity per se is not the key issue. Rather, the associated finding that comes with it.
Tortuous aneurysm. It simply means it does not lay in a straight line. You might also say it follows an erratic path rather than lying, more or less, in a straight line.

I am female but my dad had an abdominal aortic aneurysm. Does this mean I will?

Possibly. Aneurysms are caused by hypertension, atherosclerosis, and at some time, a weakness in the arterial wall. There are genetic problems which can lead to arterial wall weakness, and there can be a genetic predisposition for developing aneurysms. Read more...

Funny how a diagnosis doesn't mean much till you have it. What is abdominal aortic aneurysm?

Bulge in the aorta. The aorta is the largest blood vessel in the body, carrying blood from the heart - to the internal organs - and the legs. An aneurysm is a weakness in its wall. It bulges out and may rupture with time. Your doctor will tell you how big it is and if there are any other serious signs. If small enough, it may not need surgery, but most over 5 cm do.

Dilated aorta. Approx. 75% of aortic aneurysms are infrarenal. If the diameter of the aneurysm increases >= 0.5 cm/6mo. Period, early intervention advised. Once the aneurysm is 5cm or about twice the diameter of the non involved aorta, elective repair is advised. If 4cm dia and enlarging, repair advised to lower risk of death from exanguinating rupture. See your cardiovascular surgeon or vascular surgeon. Read more...

Arteriosclerosis. Atherosclerosis induced cystic medial necrosis is the most common cause of infrarenal abdominal aortic aneurysms. Read more...
Atherosclerosis. Atherosclerosis induced cystic medial necrosis is the most common cause of abdominal aortic aneurysms. Read more...
Weakening. We are not quite sure what actually causes an AAA to form in some people. The leading thought is that the aneurysm may be caused by inflammation in the aorta, which may cause its wall to weaken or break down. Most believe that this inflammation can be associated with atherosclerosis (also called hardening of the arteries) or risk factors for atherosclerosis, such as high blood pressure and smoking.

Run in families. Although it is not entirely clear as to what causes aneurysms, there is a definite familial predisposition to their development. If a parent or sibling has or have had an aneurysm, it is important to be checked. This can be done simply and easily with an ultrasound. Contact a vascular surgeon and have the test done at an icavl accredited vascular laboratory. Read more...

How can I treat an abdominal aortic aneurysm?

Close monitoring. It should be followed at regular intervals (at least once a year). If it reaches a specified size, enlarges rapidly, or becomes painful, it will need to be treated - either by surgery or by placement of a graft inside the aneurysm percutaneously (without surgery). Read more...
Depends on size. Large aaa's are treated with open surgery or endovascular with a stent graft. Read more...
Depends. The treatment of an abdominal aortic aneurysm depends on a number of factors. Aneurysms should be followed with ultrasound on a serial basis until they reach 5.5 CM or they exhibit rapid growth within a defined period of time. At that point the decision on how to repair the aneurysm depends on a number of anatomic factors that can be defined by an endovascular surgeon. Read more...

Why is the abdominal aortic aneurysm more common?

Not sure. We are not sure why this is the case. The most widely accepted theory is that aaas arise from an inflammatory process related to atherosclerosis. The inflammatory process is believed to degrade the elastin in the wall of the aorta, thereby weakening it. We do not produce elastin as adults. Why this process happens most often in the abdominal aorta is not clear. Read more...
Less wall elastin . The aorta, the main artery that delivers blood from the chest to the belly, has a protein known as elastin in its wall. Smoking and COPD affect biochemistry destroying elastin, leading to weakening in the wall causing it to bulge out forming an aneurysm. Why most common in abdomen? Cause elastin layer is thickest in chest thins at renal arteries in abdomen - no surprise they often form there 1st! Read more...

How do I know if I have an abdominal aortic aneurysm?

Imaging. If the aneurysm is asymptomatic, you may never know. If you have symptoms, your doctor will order appropriate testing. Most people aren't very good at feeling their own aorta, or wouldn't know where to look. Ct scan, ultrasound, abdominal xray can all see the aneurysm or evidence that one is there. Read more...

Variable. People have various experiences. I was involved with repair of a 10cm AAA one time. Read more...
Largest AAA repaired. You shouldn't think about it as, " is it too big to repair?" many anatomic details as well as a person's overall medical condition go into the decision as to if an aneurysm can be repaired. Its overall size is not a main consideration (though if its still small, they can usually be watched without repair). Read more...
