Objective To understand risk factors of abdominal aortic aneurysm (AAA) rupture and the latest progress.Method The domestic and foreign related literatures on risk factors affecting AAA rupture were retrieved and reviewed.Results Besides some definite risk factors of AAA rupture, including age, sex, hypertension, smoking, family history, complications (such as diabetes mellitus, hypertension, dyslipidemia, etc.), the biomechanical factor was the crucial factor of AAA rupture, including the aortic compliance, aortic wall peak value of pressure, aortic calcification, and hemodynamics. The latest imaging methods such as the high resolution ultrasound, function and molecular imaging, and phase contrast magnetic resonance imaging could provide technical support for the prediction of AAA rupture.Conclusion There are many risk factors affecting AAA rupture. Clinicians might prevent and make individualize treatment for AAA rupture according to its risk factors, and risks of AAA rupture could be more accurately assessed with help of new medical imaging examination.
