目的:血管系统的位置和姿势依赖性变形是一个相对未探索的领域。这项范围审查的目的是概述不同身体位置和姿势的现有血管成像方式,并解决随后的血管解剖结构变化。
方法:Scopus,Medline,和Cochrane搜索了2000年1月1日至2022年6月30日之间发表的文献,包括以下类别:图像模态,解剖学,定位,和结果。
结果:在2446篇筛选的文章中,我们包括108。大多数论文使用超声波(美国,n=74)在不同的身体位置和姿势下,以直径和横截面积(CSA)作为结果度量。磁共振成像(n=22)和计算机断层扫描(n=8)的使用频率较低,但可以用于研究其他几何测量,例如血管曲率和长度。静脉系统对姿势变化比动脉系统更敏感,这被认为是当从仰卧到易于站立的姿势时,心脏水平以下的静脉直径增加,反之亦然。
结论:使用US主要探讨了身体位置和姿势对脉管系统的影响血管直径和CSA。对血管病变的(血管内)治疗可能感兴趣的姿势引起的变形和其他几何特征的报道有限。如动脉粥样硬化动脉的长度和曲率在膝盖弯曲后放置支架。位置变化最重要的临床意义是在诊断中发现的,手术计划,支架置入后随访。
结论:本范围综述介绍了使用与临床诊断领域相关的各种成像方式对血管结构进行位置和姿势依赖性成像的现状和机会,手术计划,支架置入后随访。
结论:•使用US主要研究了身体位置和姿势对脉管系统的影响血管直径和横截面积。•研究几何变形,如血管长度和曲率适应,对于血管病变的(血管内)治疗可能感兴趣的是限于不同的位置和姿势。•在诊断中发现姿势改变的最重要的临床意义,手术计划,支架置入后随访。
OBJECTIVE: Position- and posture-dependent deformation of the vascular system is a relatively unexplored field. The goal of this scoping
review was to create an overview of existing vascular imaging modalities in different body positions and postures and address the subsequent changes in vascular anatomy.
METHODS: Scopus, Medline, and Cochrane were searched for literature published between January 1, 2000, and June 30, 2022, incorporating the following categories: image modality, anatomy, orientation, and outcomes.
RESULTS: Out of 2446 screened articles, we included 108. The majority of papers used ultrasound (US, n = 74) in different body positions and postures with diameter and cross-sectional area (CSA) as outcome measures. Magnetic resonance imaging (n = 22) and computed tomography (n = 8) were less frequently used but allowed for investigation of other geometrical measures such as vessel curvature and length. The venous system proved more sensitive to postural changes than the arterial system, which was seen as increasing diameters of veins below the level of the heart when going from supine to prone to standing positions, and vice versa.
CONCLUSIONS: The influence of body positions and postures on vasculature was predominantly explored with US for vessel diameter and CSA. Posture-induced deformation and additional geometrical features that may be of interest for the (endovascular) treatment of vascular pathologies have been limitedly reported, such as length and curvature of an atherosclerotic popliteal artery during bending of the knee after stent placement. The most important clinical implications of positional changes are found in diagnosis, surgical planning, and follow-up after stent placement.
CONCLUSIONS: This scoping
review presents the current state and opportunities of position- and posture-dependent imaging of vascular structures using various imaging modalities that are relevant in the fields of clinical diagnosis, surgical planning, and follow-up after stent placement.
CONCLUSIONS: • The influence of body positions and postures on the vasculature was predominantly investigated with US for vessel diameter and cross-sectional area. • Research into geometrical deformation, such as vessel length and curvature adaptation, that may be of interest for the (endovascular) treatment of vascular pathologies is limited in different positions and postures. • The most important clinical implications of postural changes are found in diagnosis, surgical planning, and follow-up after stent placement.
