[Mortality and morbidity in surgery for abdominal aortic aneurysm]

Area of Science:

• Vascular Surgery
• Intensive Care Medicine
• Aortic Aneurysm Research

Background:

• Ruptured abdominal aortic aneurysm (rAAA) surgery has a high mortality rate (40-50%).
• This study evaluates mortality and morbidity in rAAA patients at Rigshospitalet (RH) in 2005.
• Results are benchmarked against international data and predicted mortality.

Purpose of the Study:

• To document the mortality and morbidity of patients undergoing rAAA surgery at RH in 2005.
• To compare these outcomes with international benchmarks and predicted mortality.
• To identify factors in postoperative intensive therapy that can improve outcomes.

Main Methods:

• Retrospective analysis of mortality and morbidity data.
• Data sourced from the Intensive Care Unit (ICU) Critical Information System, blood bank, and vascular surgery database.
• Analysis included perioperative, ICU, postoperative, and 30-day mortality.

Main Results:

• Perioperative mortality was 8%, ICU mortality 22%, postoperative mortality 33%, and 30-day mortality 39%.
• ICU mortality was significantly higher for patients with renal failure and septic shock.
• Increased postoperative blood loss correlated with higher ICU mortality and morbidity. Lower initial serum creatinine (<0.100 mmol/l) was associated with lower 30-day mortality.

Conclusions:

• Treatment outcomes for rAAA at RH are comparable to leading international practices.
• Postoperative bleeding, septic shock, and renal failure are key predictors of increased ICU mortality and morbidity.
• Future rAAA therapy requires enhanced monitoring and intervention for bleeding, sepsis, and renal dysfunction.
