Regarding “Prediction of 30-day mortality after endovascular repair or open surgery in patients with ruptured abdominal aortic aneurysms”

Regarding “Identification of a genetic variant associated with abdominal aortic aneurysms on chromosome 3p12.3 by genome wide association”

“…A retrospective, multicentred, nonconsecutive sample of 500 patients undergoing aneurysm repair at general surgical units in Glasgow between 1980 and 1990 was examined for risk factors associated with death. 5,6 The poor performance of the GAS in contemporary series of patients undergoing AAA repair is unsurprising given the origins of the dataset with which it was modeled -patients treated with open surgery in low-volume, nonspecialist, general surgical units more than 20 years ago. When applied to our own series' of both retrospective and prospective data on patients undergoing attempted repair of ruptured AAA, the instrument performed with moderate accuracy at best, and lacked discriminative ability in patients at high risk.…”
