Aortic rupture is a surgical emergency, and has a high mortality even with prompt treatment. Medical therapy of aortic aneurysms involves strict blood pressure control. The prevalence of AAAs increases with age, with an average age of 65—70 at the time of diagnosis.

Anacetrapib reduces progression of atherosclerosis, mainly by reducing non-HDL-cholesterol, improves lesion stability and adds to the beneficial effects of atorvastatin [9] Elevating the amount of HDL cholesterol abdominl the abdominal area of the aortic artery in mice both reduced the size of aneurysms that had already grown and prevented abdominal aortic aneurysms from forming at all.

A bruit may be heard aortiico the turbulent flow in the aneurysm. Medical therapy is typically reserved for smaller aneurysms or for elderly, frail patients where the risks of surgical repair exceed the risks of non-operative therapy observation alone. Untreated, aneurysms tend to become progressively larger, although the rate of enlargement is unpredictable for any individual.

Another is that the abdominal aorta does not possess vasa vasorumthe nutrient-supplying blood vessels within the wall of the aorta. Decisions about repairing an aortic aneurysm are based on the balance between the risk of aneurysm rupture without treatment versus the risks of aneurissma treatment itself.

The definitive treatment for an aortic aneurysm may be surgical or endovascular repair. Most intact aortic aneurysms do not produce symptoms. It involves placement of an endo-vascular stent through small incisions at the top of each leg into the aorta. The diagnosis of an abdominal aortic aneurysm can be confirmed at the bedside by the use of ultrasound.

Endovascular treatment of aortic aneurysms is a minimally invasive alternative to open surgery repair. First, there is consideration of the risk of problems occurring during and immediately after the procedure itself “peri-procedural” complications. Ultrasound studies are obtained on a regular basis i.

When rupture occurs, massive internal bleeding results and, unless treated immediately, shock and death can occur. This can lead to inadequate blood supply to the spinal cord, resulting in paraplegia.

A rapidly expanding aneurysm should under normal circumstances be operated on as soon as feasible, as it has a greater chance of rupture.

The diameter of the aneurysm, its rate of growth, the presence or absence of Marfan syndromeEhlers—Danlos syndromes or similar connective tissue disorders, and other co-morbidities are all important factors in the overall treatment.

In short, raising HDL cholesterol aneuriska beneficial because it induces aneuriska cell death. The medical management of patients with aortic aneurysms, reserved for smaller aneurysms or frail patients, involves cessation of smoking, blood pressure control, use of statins and occasionally beta blockers. As they enlarge, symptoms such as abdominal pain and back pain may develop.

As compared to open surgery, EVAR has a lower risk of death in the short term and a shorter hospital stay but may not always be an option.

CT scan or ultrasound imaging. Risk of aneurysm rupture is weighed against procedural risk. Rarely, clotted blood which lines most aortic aneurysms can break off abdominl result in an embolus.

Aortic aneurysms cause weakness in the wall of the aorta and increase the risk of aortic rupture. Rupture risk is also related to shape; so-called “fusiform” long aneurysms are considered less rupture prone than “saccular” shorter, bulbous aneurysms, the latter having more wall tension in a particular location in the aneurysm wall.

This does not treat the aortic aneurysm per se, but control of hypertension within tight blood pressure parameters may decrease the rate of expansion of the aneurysm.
