[Surgical treatment of patients with rupture of abdominal aorto-aneurysm].

Thr experience in surgical treatment of 69 patients with rupture of abdominal aorto-aneurysm was analyzed. Multifactorial statistical analysis was carried out to determine detect influence of different parameters on postoperative lethality. The most significant parameters were initial blood loss (odds ratio (OR) -- 10.4, confidence interval (CI) -- 2.0-37.1, intraoperative hemorrhage (OR=8.5, CI 1.5-27.8), minute diuresis (OR=15,7, CI 1.8- 49.3), location of rupture (OR=12.1, CI 2.0-33.5). Combination of two and more factors led to the most unfavorable prognosis. The proposed algorithm allowed the authors to optimize treatment policy and improve significantly results of surgical treatment of patients with rupture of abdominal aorto-aneurysm: postoperative lethality has decreased from 71.4 to 28.5%.
