腹主动脉瘤(AAA)是一种临床上较常见的致死性主动脉疾病。AAA破裂与多种因素有关,如动脉瘤大小、形态、血栓形成以及血流动力学变化等。有研究表明,血流动力学变化可能为AAA破裂的主要影响因素之一。AAA有多种影像学检查方法,其中超声多普勒及磁共振血流成像技术可以对AAA的血流动力学变化进行评价。本文就AAA破裂的危险因素和影像学研究进展进行综述。 Abdominal aortic aneurysm (AAA) is a more common fatal aortic disease in the clinic. AAA rupture and a variety of factors, such as aneurysm size, morphology, thrombosis and hemodynamic changes. Some studies have shown that hemodynamic changes may be one of the main factors of AAA rupture. AAA has a variety of imaging methods, including ultrasound Doppler and magnetic resonance imaging of blood flow can be assessed on the hemodynamic changes in AAA. This article reviews the risk factors for AAA rupture and the progress of imaging studies.
