Relationship between Asymmetrical Prominent Veins Sign Based on Susceptibility Weighted Imaging and Collateral Circulation

doi:10.3969/j.issn.1673-5765.2019.07.010

Abstract

Abstract:

Asymmetrical prominent veins sign (APVS) on SWI is a characteristic imaging of ischemic stroke. Some studies suggested that APVS was associated with collateral circulation. This article reviewed the pathophysiological mechanism of APVS, the imaging features of APVS, and the correlation between APVS and collateral circulation in ischemic stroke, to provide reference for the diagnosis and treatment of ischemic stroke.

Key words: Ischemic stroke; Collateral circulation; Susceptibility weighted imaging

摘要：

MRI的SWI序列显示的不对称突出静脉征（asymmetrical prominent veins sign，APVS）可在一定程度上反映缺血性卒中的病理生理过程。新近研究显示，APVS的存在与脑侧支循环的建立存在联系。基于此，本文重点介绍了APVS的病理生理学机制、影像表现特点及其与侧支循环关系的研究现状，以期为临床诊疗提供指导帮助。
