Background: This study assesses the surgical outcome of non-infected nonruptured
abdominal aortic aneurysm (AAA) and ruptured AAA, and defines the risk factors of
death.
Methods: We studied 115 consecutive patients who underwent conventional operations
for non-infective abdominal aortic aneurysm between July 1989 and December
2003. The 115 patients were divided into two groups according to the preoperative
findings of the computed tomography (CT) scan. In group I (n=91), the patients had
AAA without CT evidence of preoperative rupture of the abdominal aorta. In group
II (n=24), the patients had AAA with CT evidence of preoperative rupture of the
abdominal aorta. Rupture was defined as free blood in the retroperitoneal or peritoneal
space. Data were collected by retrospective chart review. Both univariate and
multivariate analyses were used as risk factors for death.
Results: From 1989 to 2003, 115 patients underwent operations for abdominal aortic
aneurysm. The average patients age was 71.4±7.1 years (range, 40 to 87 years), and
99 (86%) were male. Twenty-four patients were operated upon in ruptured state. The
overall hospital mortality was 16.5% (19/115): 66.7%(16/24) in patients with ruptured
abdominal aortic aneurysm and 3.3%(3/91) in patients with nonruptured abdominal
aortic aneurysm. Risk factors for death were presence of rupture, preoperative shock
and necessity for emergency operation.
Conclusions: Mortality rates after AAA repair in our hospital were comparable
with those previously reported in other series. Major determinants of surgical mortality
in patients with abdominal aortic aneurysm were preoperative complications.
Early diagnosis and operation before aneurysm rupture were essential for survival. |
