What Causes An Aortic Aneurysm To Rupture
"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
It bursts: The wall of the aorta tears because of increased pressure from the expanding aneurysm. Ruptures can be "contained, " with the bleeding confined by the lining of the abdominal cavity, or they can be "free ruptures, " when the bleeding occurs into the abdominal cavity. The second type is more deadly. Mortality with ruptured aneurysms is 50-90%. As many as 50% of people die before reaching the hospital. ...Read more
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 more
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 more
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. ...Read more
I am suffering c.Trachomatis (recently diagnosed) since 17 yrs including aortic aneurysm and more. Am I curable? Does chronic c.Trach cause any aneurysm?
Difficult: You need to be seen and thoroughly evaluated by a good pcp and referred to appropriate specialists. Chlamydia does not produce aortic aneurysms and you do not say where in the aorta this is located, but if in the ascending aorta, syphilis must be considered. This may require surgery and outcomes are good. See someone soon and best wishes. ...Read more
Sometimes.: Probably the most important thing is controlling hypertension in patients with thoracic aortic aneurysm. Beta blockers are often helpful. However, there are many other causes, such as connective tissue disease, and even infections and inflammatory diseases which can cause taa. It is conceivable that a taa could contribute to dizziness if the great vessels are involved, but unlikely. ...Read more
The aorta: The aorta is the large, main artery that carries blood from the heart. An aneurysm (a portion that dilates or expands to a larger than normal diameter) can occur anywhere along its length, from where it emerges from the heart in the chest (thoracic aortic aneurysm) to where it travels through the abdomen & splits into the iliac arteries (abdominal aortic aneurysm, or aaa) - or anywhere between. ...Read more
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. ...Read more
Often there are none: Over 75% of aortic aneurysms are found while tests are performed for another reason. Other aneurysms are found after a thoughtful physical exam raises a suspicion for AAA and a subsequent ultrasound identifies the problem. Screening exam programs are very effective, non-invasive, and inexpensive. ...Read more
Typically non: Most of them are asymptomatic. Abdominal aortic aneurysm can cause mid abdominal and back pain sometimes. Severe pain and fever if infected. Unusually emboli or clots to legs and ischemia. Thoracic aortic aneurysm may cause back pain, or compression on structure like esophagous (difficulty swallowing), trachea or bronchus (difficulty breathing) or nerves like recurrent laryngeal nerve (horesness). ...Read more
No: Aneurysm is the dilation of your artery that can rupture if it gets too big overtime. A dissection is when the layers of your artery separate - generally associated with traumatic injuries (blunt or sharp), it is usually an acute event. Sometimes you can see dissection when the aneurysm starts to leak. Make friend with a vascular surgeon. ...Read more
Arteriosclerosis: Cigarrette smoking accelerates the process of arteriosclerosis which in turn results in atheroma formation with its multiple consequences depending on location. In the aorta it results in cystic medial necrosis leading to aneurysmal dilatation or the opposite, arteriosclerosis obliterans. ...Read more
No: Be careful if you have an AAA not to lift heavy weights. ...Read more
Depends: It depends on location and cause. Aneurysms are at risk for two major complications- rupture and dissection (which can lead to rupture or other problems such has blockage of other arteries or stroke). How quickly an aneurysm grows and the risk of rupture is related to underlying cause and annual or biannual imaging will be indicated to track the size. ...Read more
