Predicting death from ruptured abdominal aortic aneurysms

Colonic ischemia complicating open vs endovascular abdominal aortic aneurysm repair

“…In this situation, the incidence of CI is approximately 10% to 36% and, again, is dependent on whether the diagnosis is made on the basis of clinical or endoscopic findings. [26][27][28][29] The incidence of CI after repair of rAAA in our report (8.9%) is somewhat lower than average. Overall mortality rate with rupture, lack of endoscopic evaluation in all patients, lack of postmortem confirmatory data in patients who developed multiorgan system failure before the diagnosis of CI, and the population of rAAA treated with EVAR may all have contributed to a lower incidence.…”

Prediction of outcome after abdominal aortic aneurysm rupture

“…They evaluated the performance of the instrument on a prospective series of 134 patients drawn from two tertiary centers. 22 The authors argue that their system is accurate at predicting patients at extreme risk (patients with a predicted mortality Ͼ90%); however, the instrument seems to perform less well at lower levels of mortality risk (patients with a predicted mortality Ͼ80%). The group concluded that their tool was of use in informing clinical decisions in patients with ruptured AAA, although unable to identify a 100% mortality rate.…”

Reliability of Selective Surveillance Colonoscopy in the Early Diagnosis of Colonic Ischemia After Successful Ruptured Abdominal Aortic Aneurysm Repair

“…2 The mortality of rAAA repair has not altered over the last few years, with an estimated rate of 50% to 70%, whereas patients who survive rAAA are susceptible to a variety of postoperative complications, including renal failure, spinal cord ischemia, and CI. 2,10 Colonic ischemia has been reported in 15% to 35% of patients after successful rAAA repair. 11 This disastrous complication can result in 90% to 100% mortality in cases of transmural necrosis.…”
