Abdominal aortic aneurysm: a 5 years experience in Tabriz Imam Khomeini's hospital

ABSTRACT

Abdominal aortic aneurysm occurs as a result of chronic degenerative change in arterial wall. Less than 5% mortality rate has been reported for elective infra renal aortic aneurysm surgeries, however, ruptured aortic aneurysms operations have still remained as a main medical problem with a mortality rate of 30% to 70%. In this prospective study we intend to evaluate multifarious signs and factors in prognosis of 31 patients with abdominal aortic aneurism in Imam Hospital during the years 1379-1384. In this analytic-descriptive study, 31 patients with abdominal aortic aneurysm evaluated during the years 1379-1384 in Imam Hospital. These patients divided to 3 groups 1. Elective patients [10 cases], 2.Unstable ruptured aneurysms [9 cases], 3. Stable ruptured aneurysms [12 cases]. All the patients sustained transperitoneal operation. Early mortality [less than 30 days], post operative morbidity and other prognosis impressive factors were documented. Mean age was 67.1 +/- 8.9 and male to female ratio was 22.9. Early mortality occurred in 77% of unstable ruptured aneurysm group, 25% of stable aneurism group and 10% of elective group. We found no specific relation between sex and mortality. Significant relation found between mortality and systolic blood pressure at the time of admission and presence of renal disease. Mean hospital and ICU stay were 9.1 +/- 5.6 and 4.1 +/- 2 respectively. In alive patients distal embolism and renal failure were the main postoperative complications. Elective surgery increase survival in patients with abdominal aortic aneurysms. However, high rate of rapture decreases the life expectancy. Mortality rate of elective surgeries was 10%. Considering 77% of mortality rate in ruptured and unstable group, it seems evaluation for early detection and in due time operation to be an extremity
