Ten serial pathological cross sections at 1 mm intervals of both the left anterior descending artery at the site of a percutaneous transluminal coronary angioplasty and of the circumflex artery in the untreated stenotic area were studied at necropsy in a patient who died immediately after the procedure. The extent of calcification and atheroma were similar in both branches. Intimal or medial splitting, desquamation, and plaque fracture were present in the left anterior descending artery. No typical pathological findings were seen in the circumflex artery. This study suggests that the original stenotic lumen may have been enlarged as a result of plaque splitting.
在经皮腔内冠状动脉成形术部位对左前降支以及未治疗的狭窄区域的回旋支，以1毫米间隔制作十个连续病理切片，并在术后立即死亡的一名患者尸检时进行研究。两个分支中钙化和动脉粥样硬化的程度相似。左前降支存在内膜或中膜撕裂、剥脱和斑块破裂。回旋支未见典型病理表现。本研究提示，斑块撕裂可能导致原狭窄管腔扩大。
