2020年11月17日 · Saphenous vein grafts (SVG) are vulnerable to degeneration and occlusion, leading to poorer long-term disease because of atherosclerotic degeneration. The main mechanism responsible for SVG failure is neointimal hyperplasia and the occluded SVG is treated with percutaneous coronary intervention, mostly with the use of additional protection devices.

2019年4月20日 · In recent years, the spectral analysis of intravascular ultrasound (IVUS) radiofrequency data (virtual histology-IVUS [VH-IVUS]) has been used to provide quantitative assessment on both plaque compositions and morphologic characteristics.

2005年2月21日 · Therefore, the purpose of this study was (1) to use intravascular ultrasound (IVUS) to determine the arc, length, location, orientation, and distribution of SVG calcification; (2) to compare these IVUS results with angiographic findings; and (3) to correlate SVG calcification with clinical characteristics.

2012年3月22日 · 一项最新的研究对于125名svg病变接受pci治疗的患者进行了支架植入前后的ivus检查，研究发现，19例发生无复流的患者中，管腔内血栓、多发斑块破裂、斑块不规则、斑块脱垂的发生率明显高于造影正常组。

6 天之前 · OCT, the magical intraluminal coronary vision, has been a great innovation that helps us to decode many uncertainties in the morphology, behavior and vulnerability of coronary plaques. It is used widely in pre- or post-PCI or even asssit during the implantation of stents. The role of OCT/IVUS is sometimes deemed critical in dealing with left…

2005年6月21日 · Background: Ruptured atherosclerotic plaques in native coronary arteries but not in SVGs have been well described with intravascular ultrasound (IVUS). Methods: We reviewed 791 pre-intervention IVUS SVG studies and …

2018年12月12日 · Plaque composition and morphologic characteristics identified by virtual histology intravascular ultrasound (VH-IVUS) can determine plaques at increased risk of clinical events following percutaneous coronary intervention (PCI) …

Data of virtual histology (VH) acquired by intravascular ultrasound (IVUS) on saphenous vein graft (SVG) lesions is lacking. This study sought to report the VH IVUS findings in degenerative aortocoronary SVG lesions and correlate various types of …

自体大隐静脉（svg）移植仍是现今冠状动脉旁路移植术（cabg） 中最常用的旁路血管。但cabg手术的长期效果受到svg严重制约，约15%svg闭塞发生于cabg术后1月，而cabg术后10年svg闭塞率高达50%，部分原因是svg内膜增生导致粥样硬化进展甚至闭塞，进而导致不良预后。
