Recently, percutaneous transluminal angioscopy has been clinically used. We describe the evaluation of atherosclerosis by angioscopy. In observation of aortic and peripheral arteries, color of the luminal surface is yellow in the lesion without endothelial fibrosis, whereas, it is white with endothelial fibrosis. A variety of findings such as endothelial flap, endothelial thickening, mural bleeding, mural or occlusive thrombi are observed in the atherosclerotic lesions. It is difficult to detect these findings by angiography. In observation of coronary arteries, color of the luminal surface is yellow or white and often associates spiral folds in the early stage of atherosclerosis. Plaques are classified to two categories. One is the complex plaque characterised by endothelial flap, rupture of atheroma, ulceration, mural thrombus and usually observed in patients with unstable angina or myocardial infarction. Another is the regular plaque without those findings and observed in patients with stable angina. Angioscopy is useful for evaluation of atherosclerosis.
最近，经皮腔内血管镜检查已在临床上得到应用。我们描述了通过血管镜检查对动脉粥样硬化的评估。在观察主动脉和外周动脉时，病变处管腔表面颜色在无内皮纤维化时为黄色，而有内皮纤维化时为白色。在动脉粥样硬化病变中可观察到多种表现，如内皮瓣、内皮增厚、壁内出血、壁内或闭塞性血栓等。通过血管造影很难检测到这些表现。在观察冠状动脉时，管腔表面颜色为黄色或白色，在动脉粥样硬化早期常伴有螺旋状褶皱。斑块可分为两类。一类是复杂斑块，其特征为内皮瓣、粥样瘤破裂、溃疡、壁内血栓，通常见于不稳定型心绞痛或心肌梗死患者。另一类是无这些表现的规则斑块，见于稳定型心绞痛患者。血管镜检查对评估动脉粥样硬化很有用。
