| Popis: | Abdominal aortic aneurysm (AAA) is a vascular disorder in which an abnormal and non-reversible dilation develops within the infrarenal aorta. Most AAAs remains asymptomatic until catastrophic rupture. The overall mortality rate resulted by AAA rupture is between 65% and 90%. AAA rupture claims about 15,000 lives in the United States per year, making it the 15th leading cause of death in the country. Recent advances in cardiovascular medicine have not lowered AAA mortality rate globally.Prevention of rupture is a main goal of AAA management. Currently, AAA size has been used to evaluate its rupture potential. Aneurysm repair is usually recommended when the maximum diameter exceeds 5.5 cm. Multiple studies have suggested that this criterion may not be reliable, especially for small AAAs |
