以桡动脉为移植体行冠状动脉旁路术的局解手术学研究

A Topographic Operative Study of Coronary Artery Bypass with Raeial Artery Autograft

本文对104侧上肢桡动脉第一段和63例成人离体心脏之冠状动脉及其主要分支,根据临床应用进行了观测。结果:桡动脉长度为22.10±1.2cm;外径(下同):上端为3.00±0.6mm,下端为2.60±0.6mm。后降支(房室交点下1cm处)为2.41±0.4mm,左右心耳与肺劝脉交角下1cm处的前降支为3.83±0.6mm,右冠状动脉主干为3.79±0.7m。距离:自主动脉前窦上2cm至前降支中点的长度为6.61±0.5cm,经右冠状沟至房室交点的长度为11.80±1.5cm。测量数据提示:以桡动脉为移植体足以吻接任何冠状动脉。本文尚阐述和讨论了该术式的局解手术学基础和操作程序,对冠状动脉旁路术(CABO)

The radial arteries (first segment) of 104 up-per limbs, the coronary arteries of 63 cases were dissected and measured on their topography and operative surgery. The length 11 of radial arteries is 22. 0±1. 2cm, the diameter is 3. 0±0. 6mm-2. 6±0. 6mm. In this study,the author found that the lenth and diameter of radial artery are suitable in length and diameter for corinary bypass.
