What are possible causes of most aneurysms of the abdominal aorta?

What are possible causes of most aneurysms of the abdominal aorta?

Atherosclerosis: Some theories about collagen, ischemic wall etc, but most are in atherosclerotic vessels in abdomen or elsewhere. Aneurysms can happen in any blood vessel, but AAA is the most common. Some rare infections , congenital, traumatic. ...Read more

Aorta (Definition)

The aorta is the largest artery in the body, leaving directly from the left ventricle of the heart to supply blood to the entire body. It is made of elastic tissue layers called "intima" and is subject to damage by high blood pressure, smoking, cholesterol, ...Read more

What is the presumed cause of most aneurysms of the abdominal aorta?

What is the presumed cause of most aneurysms of the abdominal aorta?

Several theories: Most common belief is that aneurysms develop due to some inherent weakness in the artery's muscular layer due to an imbalance of collagen metabolism or genetic collagen abnormalities. The only independent risk of aneurysm growth is high blood pressure and smoking. ...Read more

If u don't have aneurysm and a 14mm abdominal aorta u have thinner wall than 20mm healthy aorta and therefore lower tolerance for pressure? Sorry

If u don't have aneurysm and a 14mm abdominal aorta u have thinner wall than 20mm healthy aorta and therefore lower tolerance for pressure? Sorry

14 mm: I've never heard of a 14 mm aorta rupturing. Wall stress is related to diameter. Unless you have some very rare condition that you haven't told us about or a family history of everyone dying of ruptured aortas, my inclination is to say you're at lower than average risk. ...Read more

Is a 22 more likely to get an aneurysm of abdominal aorta or thoracic? What's more rare? If u have high BP for 6 months?

Is a 22 more likely to get an aneurysm of abdominal aorta or thoracic? What's more rare? If u have high BP for  6 months?

Aneurysm: It would be extremely rare for a 22 yo to develop an aneurysm as a result of 6 months of hypertension. Thoracic is much less common than abdominal aortic aneurysms which are a result of decades of sustained high pressure in the aorta. Do you suffer from anxiety disorder or OCD? I would suggest that is much more likely in a 22 yo male who is preoccupied with this than AAA from hypertension. ...Read more

Could u detect an thoracic aneurysm on a ultrasound of abdominal aorta or of heart? Or chest xray? Or what could u detect regarding aneurysms?

Could u detect an thoracic aneurysm on a ultrasound of abdominal aorta or of heart? Or chest xray? Or what could u detect regarding aneurysms?

Aneurysm: Abdominal aortic ultrasound might detect aneurysm of the thoracic aorta just before it enters the abdomen, otherwise would not be good to detect thoracic aneurysm. Echocardiogram can detect thoracic aneurysm. Chest X-ray might detect it if it is large. ...Read more

A xray of my lumbar spine showed a abdominal aorta anuerysm at L4-L5. A follow up C-Scan for a fracture reports, the abdominal area is unremarkable.?

A xray of my lumbar spine showed a abdominal aorta anuerysm at L4-L5. A follow up C-Scan for a fracture reports, the abdominal area is unremarkable.?

Review with your Dr: Hi Please review the radiology results with your doctor. Generally speaking, we are able to see finer detail of internal organs on CT scans than on X-rays. We typically order CT scans to confirm, refute, or gather more information about questionable findings on X-rays. Below is a link with further information regarding imaging of Abdominal Aortic Aneurysms. Hope this helps! http://bit.ly/2hnK5LH ...Read more

Is it a problem if you have a beating abdominal aorta?

Is it a problem if you have a beating abdominal aorta?

Aorta: Blood flows through the aorta as it is pumped around the body by the heart. If you don't have 'beating' or blood flow in the aorta, you have serious trouble. If the aorta gets stretched out and enlarged, that is a problem called aneurysm. ...Read more

What is ectatic abdominal aorta?

What is ectatic abdominal aorta?

Bigger than normal: An ectatic abdominal aorta is one that is bigger than normal but not quite an aneurysm, which is defined as having a diameter that is 1.5X larger than that of a normal segment of aorta. A normal aorta for a man may be somewhere between 18-26 mm, though this is not hard and fast rule. There is general agreement that an aorta measuring 40 mm or greater would be considered an aneurysm, however. ...Read more

If X-ray shows abdominal aorta (enlarged) does that mean plaque problem?

It might: Typically an enlarged aorta is due to an anuerysm. The anueysm may or may not contain cholesterol plaque. Aortic aneurysms are repaired once they reach a certain size due to the risk of rupture. People with aortic anuerysms should follow up routinely with a vascular specialist for ongoing management of the condition (cardiologist or vascular surgeon). ...Read more

In x-ray findings, the Dr. said that there were extensive artherosclerotic, changes in the visualized abdominal aorta. What does this mean?

Calcium: There is calcium in the wall of the aorta +/- iliac arteries. This is arteriosclerosis or "hardening" of the arteries. This may not need treatment. ( other than not smoking, keeping BP and cholesterol under control). A vascular surgeon can tell you if additional testing or treatment is necessary. ...Read more

If you have 14mm abdominal aorta as a 23 yo, you will have thinner walls than if you had 2cm healthy aorta and so a weaker aorta. More prone to burst?

If you have 14mm abdominal aorta as a 23 yo, you will have thinner walls than if you had 2cm healthy aorta and so a weaker aorta. More prone to burst?

Just the opposite: Aortic aneurysms have a higher risk of rupture with increasing diameter. Generally they are treated expectantly with observation and antihypertensives if necessary until they become symptomatic (with pain or showering emboli distally), or enlarge greater than 5 cm. The two methods of fixing them are with a traditional operation or more recently, stent placement. ...Read more

Would abdominal aorta problem show up on a abdominal X-ray when checking for appendictis?

Usually not: The aorta and/or aneurysms usually can't be seen on a regular x-ray (neither can an appendix) but if the aneurysm is very calcified, one might get a suggestion of an aneurysm. ...Read more
