[Effect of improved surgical anesthesiologic factors on the results of treatment of aneurysms of the abdominal aorta]. / Vrednovanje utjecaja poboljsanja operacijskih anestezioloskih cimbenika na rezultate lijecenja aneurizmi abdominalne aorte.

ABSTRACT

The purpose of this study was to compare the recent results of the abdominal aortic aneurysm (AAA) surgery, with the results for the patients operated ten years ago, and to identify the factors influencing the operative results. Two groups of patients were selected using a retrospective case series study. First group of patients (A) consisted of 32 cases operated in the period between 1984 and 1986, and the second group (B) consisted of those operated ten years later (from 1994 to 1996). Mortality rate, presence of risk factors, demographic data, and operative factors were analyzed and compared between the groups. The mortality rate decreased from 10.7% in period A, to 5.3% in period B for elective operations, and from 75% to 44.4% for emergency operations. The prevalence of straight graft technique in period B showed statistically significant difference compared to period A (p < 0.005). Besides, the operating time and the amount of the transfused blood between the groups differed significantly (p < 0.05). On the basis of this data, we concluded that the modifications in the operative technique, as well as the increased number of operations within the second period led to the decreased mortality rate in patients operated for AAA.
