冠状动脉起源异常29例

目的：了解冠状动脉起源异常（coronary artery origin anomalies,CAOA)的情况。方法：回顾性分析我院从1995至2001年2416例冠状动脉造影结果。结果：CAOA29例（1．2％），其中左前降支（LAD）和回旋支（LCX）分别独立起源于左冠状窦17例（58．6％），右冠（RCA）起源于左冠状窦6例（20．7％），RCA起源于升主支脉1例（3．4％），LCX起源于右冠状窦4例（13．8％）LCX起源于RCA1例（3．4％）；29例患者中除5例（17．2％）合并有冠状动脉狭窄外，其余24例（82．8％）患者未见冠状动脉狭窄。结论：CAOA是影响冠状动脉造影响的因素之一，但细胞观察左心室造影结果，选用不同型号的造影导管，终能满意地显示冠状动脉。最常见的类型是LAD和LCX分别独立起源于左冠状窦，大多数异常类型并不导致严重的临床症状，只有少数需要外科手术治疗。

Coronary artery origin anomalies :analysis of 29 cases.

Objective To gain an understanding of the coronary artery origin anomalies(CAOA).Methods The data on 2416 cases of coronary arteriography at our hospital from 1995 to 2001 were reviewed and analyzed.Results CAOA were confirmed in 29 patients(1.2%).The incidence for separate origin of LAD and LCX from the left sinus of Valsalva(58.6%)was the highest.RCA was found originating from the left sinus of Valsalva in 6(20.7%),from the ascending aorta in 1( 3.4 %).Anomalous LCX from right sinus of Valsalva was seen in 4(13.8%),and from RCA in 1(3.4%).Only 5(17.2%) patients had coronary stenosis.Conclusion In our caseseries,separate origin of the left anterior descending and circumflex from the left sinus of Valsalva was the commonest coronary artery origin anomalies.It does not appear to be an increased risk for the development of atherosclerotic coronary artery disease in anomalous coronary arteries.Only a few cases of coronary artery anomalies require surgical correction.
