Analysis of perioperative mortality rate in patients with abdominal aortic aneurysm treated at the Department of General and Vascular Surgery, Silesian Medical University in 1978-2005
open access
Abstract
Material and methods: From 1978 to 2005, 1620 patients with infrarenal AAA were treated electively. In the same period, 318 patients with ruptured AAA were operated on. In this study, treatment results in patients operated on during 1978-2005 were retrospectively evaluated. The assessment criterion was the perioperative mortality rate. Additionally, AAA treatment results divided in 3 time intervals: 1978-1990, 1991-2000, 2001-2005 were compared. The division into particular time intervals was dictated by the increasing experience of the surgical team and the introduction of new operative techniques.
Results: The mean mortality rate value in ruptured AAAs was 56.6% during 1978-2005. In non-ruptured (symptomatic and asymptomatic) AAA, the mean mortality rate value was 9% during 1978-2005. A fact worth noticing is that in 2005 the perioperative mortality rate accounted 3.7%. If patients treated with elective operation due to asymptomatic AAA were distinguished, the mortality rate was 4.4% during 1978-2005, whereas in 2005 it merely reached 1.2%.
Conclusions: The number of patients treated due to AAA is constantly increasing, which is unquestionably associated with the improvement of aneurysm detection. Yet the number of high risk patients with a large aneurysm has not decreased, which suggests the possibility of further AAA detection improvement, and what follows, the earlier beginning of treatment in patients in a better general condition, guaranteeing an improvement in treatment results.
