Glasgow Aneurysm Score predicts survival after endovascular stenting of abdominal aortic aneurysm in patients from the EUROSTAR registry

Abstract

The GAS was effective in predicting outcome after EVAR. Because its efficacy has also been shown in patients undergoing open repair of AAA, it can be used to aid decisions about treatment in all patients with an AAA.

The Glasgow Aneurysm Score as a tool to predict 30-day and 2-year mortality in the patients from the Dutch Randomized Endovascular Aneurysm Management trial

“…Third, The high cutoff value for predicting perioperative death after EVAR treatment compared with OR is not very surprising and has been shown previously in a study of 5498 patients of the EUROSTAR Registry. 12 Strikingly, we found an identical optimal cutoff value for 30-day EVAR mortality (86.5) as the previous study (86.6), which indicates that our study is representative despite the low number of events.…”

“…The GAS was originally designed to predict perioperative mortality and morbidity after OR, but a recent report from the European Collaborators on Stent-graft Techniques for Abdominal Aortic Aneurysm Repair (EuroSTAR) showed that the GAS may also be a good predictor of both perioperative and long-term results after EVAR treatment. 12 Although the DREAM trial patients were considered to be suitable for both open and endovascular repair, this decision was not based on standardized risk-stratification systems. Consequently, it is conceivable that patients were included in the DREAM trial who actually had an elevated risk of dying in the first 2 years after surgery based on a scoring system like the GAS.…”

Acceptable Risk but Small Benefit of Endovascular Aneurysm Repair in Nonagenarians

“…Several models (e.g., Glasgow Aneurysm Score, modified Leiden score) have been created to help predict perioperative mortality with open aortic procedures. 13,14 However, age is such a prominent predictor in these models that, even without any associated risk factors, age over 80 alone would portend such a high risk of procedure-related morbidity and mortality that patients may be excluded from consideration for surgical management.…”

Defining high risk in endovascular aneurysm repair

“…Recently, an interest has begun to relate preoperative variables with long-term survival in the endovascular population. [1][2][3] Periprocedural risk assessment should include the relative likelihood that aneurysm rupture is the strongest of all competing factors contributing to late mortality. To date, there exists no system, developed, and validated in a population of aneurysm patients, to predict when treatment will prolong longevity.…”
