人体冠(状动)脉粥样硬化过程中局部管径是否代偿性增粗,迄今仍有争议。 Chicago大学病理系(1983.12.1～1984.12.28)将63±16(18～98)岁的136(男83、女53)例除主动脉瓣返流和传染病外各种疾病患者的心脏于死后2～12小时内取出,当时109只心脏标本经称重为446±148(200～850)g。心脏标本经适当处理后,使冠脉保持充盈状态。鉴于左主干常有病变且其长度、管径较为一致,故截取左主干(左冠脉开口处至左回旋支起始部之间)中段备检。136支左主干中,2支粥样斑块内有新鲜出血灶,3支腔内有血栓。出血灶和血栓的截面积从粥样斑块的截面积(Le)中扣除,分别
There is still controversy so far whether the local diameter of the coronal (motoneurotic) atherosclerosis is compensatory thickening or not. Department of Pathology, University of Chicago (1983.12.1 ~ 1984.12.28) A total of 136 patients (83 males and 53 females) aged 63 ± 16 (18-98 years) with aortic valve regurgitation and infectious disease Removed within 2 to 12 hours after the death, when 109 heart specimens were weighed 446 ± 148 (200 ~ 850) g. After proper treatment of the heart specimen, the coronary artery is kept fully filled. In view of the left main artery often lesions and its length, diameter is more consistent, so interception of the left main (left coronary artery opening to the beginning of the left circumflex artery) in the middle of the test. Of the 136 left main trunks, 2 had fresh hemorrhagic foci within 2 plaques and 3 had intracavitary thrombi. The cross-sectional area of the hemorrhage and thrombus was deducted from the cross-sectional area (Le) of the atherosclerotic plaque, respectively
