1879例成人非先天性心脏病患者双源CT检出的冠状动脉起源异常24例分析

目的：评价双源CT（DSCT）在成人非先天性心脏病患者冠状动脉起源异常检出中的价值。方法：回顾性分析2008年9月，2009年2月期间进行了DSCF冠状动脉检查的资料，总结成人非先天性心脏病患者冠状动脉起源异常的检出率。结果：1881例进行冠状动脉检查的患者中，共有1879例患者为非先天性心脏病患者，共检出了24例冠状动脉起源异常，检出率为1．3％。其中15例为右冠状动脉起源异常（12例起自左冠状窦，3例为高位起源），8例为左冠状动脉起源异常（3例起自无冠状窦，回旋支起自左冠状窦、高位开口、回旋支起自右冠状动脉、左冠状动脉起自右冠状窦、单一冠状动脉各1例），1例为左右冠状动脉均起源异常（均为高位开口）。结论：本组成人非先天性心脏病患者冠状动脉起源异常的检出率为1．3％。DSCT可很好地显示冠状动脉起源异常和走行，为临床决策提供重要信息。

Incidence and significance of 24 cases of anomalous origin of coronary artery in 1879 adult patients without congenital heart disease on dual-source computed tomography angiography

Objective：The purpose of this study was to assess the clinical value of dual-source CT （DSCT） in detecting anomalous origin of coronary artery for adult patients without congenital heart disease （CHD）. Methods： We summarized all patients who underwent DSCT coronary angiography from Sep 2008 to Feb 2009, and data of anomalous origin of coronary artery for adult patients without CHD were recorded. Results： 1879 patients has no CHD in 1881 patients underwent DSCT coronary angiography during the duration, 24 patients with anomalous origin of coronary artery were detected, giving the incidence of 1.3%. 15 patients had anomalous origin of right coronary artery （12 from left coronary sinus, 3 high take off）, 8 patients had anomalous origin of left coronary artery （LCA from noncoro- nary sinus in 3 cases, LCX from left coronary sinus, LCX from RCA, high take off, lEA from right coronary slum, and single coronary artery in one ease, respectively）, 1 patient had anomalous origin of both coronary arteries （high take off）. Candusion：The incidence of anomalous origin of coronary artery for adult patients without CHD in this study is 1.3%. DSCT can clearly visulaize anomalous origin and course of coronary artery as a useful screening modality.
