AbstractOne hundred and thirty two patients who underwent aortic surgery at King Chulalongkorn
Memorial Hospital, Bangkok, Thailand from January 1991 to December 2000 were studied. Twenty
three patients (17.4%) were aged less than 60 years, 102 (77.3%) aged 60-80 years, and 7 (5.3%)
were older than 80 years., Ninety eight patients (74.2%) underwent elective operations and 34
(25.8%) underwent emergency operations. Elective abdominal aortic aneurysms (AAA) repair was
the most common indication for abdominal aortic surgery (56.0%). Eighteen patients (13.6%)
underwent surgery for infected AAA. The incidence of infected AAA was 16.1 per cent among
patients with AAA. Fifteen patients ( 11.4%) had ruptured AAA and 19 patients ( 14.4%) had
aortoiliac occlusive disease. The overall mortality rate was 15.2 per cent. The mortality of elective
aortic surgery was 5.1 per cent and of emergency aortic surgery was 44.1 per cent. The morta-
lity of elective AAA repair was 4 per cent. Multiple system organ failure was the most common
cause of death (80%), followed by acute myocardial infarction (10%) and exsanguination (10%).
The authors conclude that elective surgery on the abdominal aorta is safe and should be performed
when indicated to prevent the development of complications requiring emergency surgery which
carries a much higher risk.
