[Ruptured abdominal aortic aneurysm : perioperative indicators for the clinical course following conventional open surgery].
OBJECTIVE
Ruptured abdominal aortic aneurysms (rAAA) still represent a life-threatening vascular disease, with high mortality despite improved diagnostic tools and perioperative patient management. The aim of this study was to reveal predictors of perioperative mortality and survival after open (conventional) rAAA repair.


METHODS
We analyzed data from our department containing 67 patient histories and clinical notes which were collected between January 1984 and December 2004. The study patients underwent emergent surgery for rAAA. In these cases we defined 72 preoperative, 47 intraoperative, and 39 postoperative variables for further analysis.


RESULTS
Our results indicate that the worst survival prognosis could be defined in patients with rAAA and aneurysmatic inclusion of the iliac arteries with concomitant prolonged shock who received an aorto-iliac bypass. For these patients we calculated a cumulative 30-day survival rate of 59.7% and 1-year survival of 43.3%. An influence of age and comorbidity on the mortality rate could not be proven. Furthermore the conclusion cannot be drawn that postoperative course was influenced by intra- vs retroperitoneal rupture localization.


CONCLUSIONS
This study provides evidence that neither old patient age nor comorbidities influence the mortality of patients suffering from rAAA, for whom time-consuming case selection according to previous morbidities should therefore be omitted. Instead we recommend conventional surgical repair as soon as possible to maximize the chances of survival.
