What are the prognostic factors and surgical outcomes for patients with ruptured abdominal aortic aneurysm?
Absolute Event Rate: 50% vs 4%
p-value: p=<0.01
Ruptured abdominal aortic aneurysm carries a high hospital mortality rate of 50%, strongly influenced by older age, preoperative shock, and postoperative complications, highlighting the need for elective repair of non-ruptured AAA.
Ruptured AAA's high mortality warrants clinical vigilance in at-risk patients; extends cohort evidence on prognosis but leaves optimal prevention open.
We investigated factors influencing the prognosis of patients with ruptured abdominal aortic aneurysm (AAA) who underwent operations during the past 10 years. In 97 patients with AAA, 22 (22.7%) ruptured. The mean age of the patients with ruptured AAA (n=22, 70.2 y) was higher than that of the patients with non-ruptured AAA (n=75, 67.6 y). Especially, the mean age of the female patients with ruptured AAA (79.8 y) was higher than that of the male patients with ruptured AAA (67.4 y). The rate of hospital death among patients with ruptured AAA (50%) was significantly higher than that among patients with non-ruptured AAA (4 %). The mean interval from onset to surgery in the hospital death patients (25 hr) was shorter than that in the surviving patients (29 hr). Preoperative shock was more frequently in hospital death patients than in surviving patients. Hospital death patients were transfused significantly more than surviving patients. Postoperative complications, such as renal failure, central nervous system disturbance and multiple organ failure, were frequently observed in hospital death patients. To improve the survival rate of patients with ruptured AAA, we must make an effort to reduce postoperative complications. Mass screening of high risk patients with AAA is also needed to predict patients with non-ruptured AAA.

Yokoe et al. (1994) conducted an observational in Abdominal aortic aneurysm (n=97). Ruptured abdominal aortic aneurysm vs. Non-ruptured abdominal aortic aneurysm was evaluated on Hospital death (p=<0.01). Ruptured abdominal aortic aneurysm was associated with a significantly higher hospital mortality rate (50%) compared to non-ruptured aneurysm (4%, p<0.01).
