How are aortic aneurysms caused?

Question

Do you know how aortic aneurysms are caused in someone with oi?

Answer 1

Aortic Aneurysms: It is not entirely clear exactly what causes aortic aneurysms, but we know of a few risk factors, probably the most significant of which is smoking. Other risk factors include atherosclerosis and high blood pressure. There is also a hereditary component, so these can run in families. There are also genetic syndromes such as Marfan's or ehlers-danlos which are associated. See a vascular surgeon.

Answer 2

Occur not caused: Congenital familial rare Marfan etc atherosclerosis and wall deterioration over time with dilation some after dissection some after trauma- more pseudoaneurysms from that.

Answer 3

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.

Answer 4

Many: "causes" are associated problems that are thought to be the reasons. Remember, though, that association is not necessarily causation. That said, more important is what to do about presence of aneurysm. Since there is weakness in the "pipe", this needs to be evaluated whether treatment is necessary, urgent or elective, or not at all. Seeing a vascular surgeon for an opinion is needed.

Answer 5

Many: Many causes such as high cholesterol, smoking, uncontrolled BP and certain genetic causes as well as sudden deceleration injuries.

Answer 6

Multiple factors: Smoking and certain genetic factors contribute to the development of aortic aneurysm. Maintaining a normal cholesterol and lipid profile can help reduce your risk too.

Answer 7

Known risk factors: Certain aneurysms are caused by genetic predispositions that is caused by such conditions as marfan's syndrome. Otherwise the usual cardiovascular risk factors such as hypertension, diabetes, hypercholesterolemia and smoking.

Answer 8

Congenital or acquir: There is a 10% family inheritance if you have a first degree relative with an aneurysm. There is a strong disposition between smoking and hypertension as well..

Answer 9

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.

Answer 10

Unknown : There are factors thought to be associated with the development of an aortic aneurysm such as genetic problems with an enzyme called elastase, other types of collagen disorders, and possibly hypertension. It is difficult, if not impossible, to detect the specific cause for most individual patients.

Answer 11

Abdominal (AAA)?: 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.

Answer 12

Cause of aneurysm: With the exception of a few genetic conditions like marfan's or ehlors danlos and a couple others we haven't established the exact cause of the vast majority of aortic or peripheral aneurysms.

Answer 13

Aortic aneurysms: Aortic aneurysms are commonly associated with high blood pressure. They also have a familial ncidence probably due to collagen structure. Some genetic syndromes commonly are associated with aortic aneurysms. Some inflammatory diseases can involve the aortic wall and cause aneurysms. Atherosclerotic disease can also be an association.

Answer 14

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.

Answer 15

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.

Answer 16

Lot of things: Atherosclerosis (hardening of arteries), aging, infection (syphilis for one), traujma, some congenital problems such as marfan's or ehlers-danlos where there is inherited weakness in the artery wall, and inflamation. Hypertension can cause a "dissecting aneruysm" ( a tear in the aorta).

Answer 17

Arteriosclerosis: Most arteriosclerotic aneurysms result in cystic medial necrosis of the aorta resulting in dilatation of the artery secodary to the internal pressure and weakness of the arterial wall. Any part of the aorta and its branches may be affected. Infections with bacteria, fungus, syphillis may also produce aneurysms in the aorta.
