近30年来,由于医学影像技术的发展,不少学者认识到颅内动脉瘤的发生、生长、血栓形成和破裂与血流动力学密切相关。越来越多的证据表明,颅内囊性动脉瘤的发生是由于血流动力学因素诱发血管壁继发性损伤造成。因此,有关颅内动脉瘤血流动力学的研究陆续见到报道。其研究手段各异,得出的结论也不尽相同。本文从以下几个方面对这些研究进行综述。 Nearly 30 years, due to the development of medical imaging technology, many scholars have realized that the occurrence of intracranial aneurysms, growth, thrombosis and rupture and hemodynamics are closely related. More and more evidences show that the occurrence of intracranial cystic aneurysms is due to hemodynamic factors induced by secondary damage to the vascular wall. Therefore, the study on hemodynamics of intracranial aneurysms have been reported. The research methods are different, the conclusions drawn are not the same. This article reviews these studies in the following areas.
