The aneurysm is a disease specialty vascular surgery . In case of rupture of the aneurysm of the abdominal aorta, mortality approaches 90%.
It is understood as aneurysm permanent localized dilatation of an artery, with an increased diameter of more than 50% compared to the normal diameter. The most common aneurysm is the abdominal aortic infrarenal. It is more common in men, with an estimated prevalence of 3% in men over 50 years.
Aneurysms form by degeneration of the arterial wall. Among the factors that favor its appearance include: age, snuff and family or genetic predisposition.
During its development does not usually generate alarm symptoms. The most feared risk breakage. The abdominal aorta aneurysms broken lead to a mortality of 90%. Only when you start to get complicated, manifest as a pain, shock, ... which may correspond to the beginning of a break that involves death quickly. Although it is very difficult to quantify accurately, some of the calls 'sudden deaths' correspond to the breakage of abdominal aortic aneurysms (AAA).
As aneurysms do not show their faces until they begin to get complicated, it is advisable to make an early diagnosis before it's too late. Therefore, in some countries programs for early diagnosis of AAA apply risk population groups. That is, men over 65, smoking or a family history of AAA.
Aneurysms at risk for rupture, should be treated as preventive and scheduled before breaking irreversibly. There are two surgical procedures to repair AAA. Conventional surgery aims at replacing the aneurysmal segment with a prosthetic vascular artery by surgical exposure of the aorta.
The other mode is the endovascular treatment, which is aimed at excluding the AAA by implanting an endoluminal prosthesis applied catheterization technique. Currently, between 55-75% of endovascular AAA repair technique. Fortunately, aneurysms in other locations now can be treated with this new technique.
