PURPOSE
This paper aims to provide the tools for a complete anatomical evaluation of the coronary tree using 64-slice computed tomography (CT) and evaluate the prevalence of anatomical variants and anomalies in a population of 202 consecutive patients.
MATERIALS AND METHODS
Two hundred and two patients with suspected coronary artery disease underwent 64-slice CT with a standard protocol. Two observers working in consensus evaluated and collected the data regarding anatomical variants and anomalies of the coronary vessels.
RESULTS
In the 202 consecutive patients, the prevalence of anatomical variants was: left dominant circulation (7%), absent left main (5%), presence of intermediate branch (17%), aortic origin of conus branch (13%) and circumflex origin of sinus node branch (15%). Coronary anomalies (origin and course, intrinsic and termination) showed an overall prevalence of 25%.
CONCLUSIONS
CT is the ideal method for the three-dimensional evaluation of the coronary tree. Anatomical variants and anomalies of the coronary arteries are quite common and should be known and recognised promptly by the operators.
目的
本文旨在提供利用64层计算机断层扫描（CT）对冠状动脉树进行完整解剖评估的工具，并评估202例连续患者群体中解剖变异和异常的发生率。
材料与方法
202例疑似冠心病患者接受了标准方案的64层CT检查。两名达成共识的观察者对冠状动脉血管的解剖变异和异常数据进行了评估和收集。
结果
在这202例连续患者中，解剖变异的发生率为：左优势型循环（7%）、左主干缺如（5%）、中间支存在（17%）、圆锥支起源于主动脉（13%）以及窦房结支起源于回旋支（15%）。冠状动脉异常（起源和走行、本质和终止）的总体发生率为25%。
结论
CT是对冠状动脉树进行三维评估的理想方法。冠状动脉的解剖变异和异常相当常见，操作人员应及时了解并识别。
