血流动力学与脑部血管周围间隙扩大关系的研究进展 Advance in Relationship between Cerebral Hemodynamics and Enlarged Perivascular Space

Abstract

脑部血管周围间隙扩大是脑小血管病的影像学标志物之一，其发生发展的机制尚不明确。 现有研究表明血流动力学改变可能引起血管周围间隙扩大的发生发展。本文从血压、血管管壁僵硬 程度、脑血流量等因素对血管周围间隙扩大的影响作一简要综述，为探索血管周围间隙扩大的发病 机制及可能的治疗方法提供帮助。 Abstract: The enlarged perivascular space is one of the neuroimaging markers of cerebral small vessel disease. The mechanism of perivascular space enlargement is still unclear. Many studies have shown that abnormal hemodynamics may be correlated with the enlarged perivascular space. This article reviewed the relationship between blood pressure, stiffness of vessel wall and cerebral blood flow with the enlarged perivascular space, to provide reference for studies of pathogenesis and possible treatment methods of enlarged perivascular space.
