New scale for predicting mortality in ruptured abdominal aortic aneurysms

Area of Science:

• Vascular Surgery
• Medical Informatics
• Clinical Outcomes Research

Background:

• Endovascular repair is a treatment for ruptured abdominal aortic aneurysms.
• Predicting mortality risk is crucial for treatment decisions.

Purpose of the Study:

• To evaluate the utility of mortality risk scores in endovascular treatment for ruptured abdominal aortic aneurysms.
• To identify key predictors of in-hospital mortality.

Main Methods:

• Retrospective analysis of 61 patients undergoing endovascular repair (2009-2014).
• Collected preoperative variables and in-hospital mortality data.
• Calculated Hardman, GAS, Vancouver, and ERAS risk scales.

Main Results:

• In-hospital mortality was 45.9%.
• Significant predictors identified: age, systolic blood pressure <90mmHg, and heart rate.
• A novel risk score formula demonstrated an AUC of 0.95.

Conclusions:

• Age, systolic blood pressure, and heart rate are key predictors of mortality in this patient group.
• The proposed scale, combined with existing scores (GAS, Vancouver, ERAS), aids in identifying patients unsuitable for endovascular repair.
