冠心病导管介入治疗形态学基础的研究

Morphological basis of catheter interventional therapy for coronary heart diseases

目的：测定心脏的血管管径为临床介入治疗提供形态学基础。方法：用游标卡尺对15例心脏左、右冠状动脉，冠状窦及静脉属支的管径进行了测量。结果：各血管中段内外径分别为：左冠状动脉前空间支1．8±O．4mm，2．9±O．5mm；右冠状动脉后室间支1．4±0．4mm，2．3±0．5mm。心大静脉2．7±0．6mm，3．5±0．5mm。结论：本研究测定的数据可为冠状动脉粥样硬化血管狭窄时，采用球囊血管成形术、腔内斑块旋磨术或斑块直接切除术、血管内支撑器等介入治疗方法提供形态学基础。

0bjective: Measuring the diameter of cardiac vessels for catheter interventional therapy of coronary heart diseases. Methods: The diameters of the mid-portion of left, right coro-nary artery, coronary sinus and venous branch of 15 cadavers were measured with caliper. Results: The internal and external diameters of the mid-portion of different blood vessels were as follows: (l ) The anterior interventricular branch was 1. 8t O. 4mm and 2' 9± 0. 5mm respectively. (2) The posterior interventricular branch was l. 4±O. 4mm and 2. 3l± O. 5mm respectively. (3) The great cardiac vein was 2. 7±O. 6mm and 3. 5±O. 5mm respectively. Conclusl0n: The data measured may offer morphological bases for interventional therapy of coronary heart diseases such as ballon an-gioplasty, transluminal coronary rotational ablation or atherectomy, endovascular stent in patient with coronary arteriosclerotic stenosis-
