摘要

我们试图研究是否可以通过现代成像技术无创地评估腔内血栓(ILT)的机械特性。在体内评估血栓的压缩性和变形。报告:5例患者在腹主动脉瘤(AAA)监测期间接受了心电图(ECG)门控计算机断层扫描。记录收缩期高峰和舒张期末期ILT体积和横截面积，发现其保持不变。ilt弹性行为可以非侵入性地估计。在生理性动脉压力下，ILT是不可压缩的，不会纵向变形。

Aneurysm Intraluminal Thrombus Compressibility Estimated in vivo Using Electrocardiographically Gated Computed Tomography: A Feasibility Study

Introduction

We attempt to investigate if the mechanical properties of an intraluminal thrombus (ILT) could be assessed non-invasively through modern imaging techniques. Thrombus compressibility and deformation are evaluated in vivo.

Report

Five patients underwent electrocardiographically (ECG) gated computed tomography scan during surveillance of their abdominal aortic aneurysm (AAA). ILT volumes and cross-sectional areas during peak systole and end diastole were recorded and found to remain constant.

Discussion

ILT elastic behaviour can be estimated non-invasively. Under physiologic arterial pressure, an ILT is incompressible and does not deform longitudinally.
