摘要
目的:探讨双源CT(DSCT)对冠状动脉异常起源于肺动脉的诊断价值。方法:回顾性分析经DSCT诊断为冠状动脉异常起源于肺动脉(ACAPA)的27例患者的临床和影像资料,其中发病年龄≤1岁7例(25.9%),1~7岁7例(25.9%),>7岁13例(48.2%),随访所有患者的治疗及预后。结果:DSCT对27例ACAPA均明确诊断,其中左冠状动脉(LCA)异常起源24例,右冠状动脉(RCA)异常起源3例。20例DSCT显示大量侧枝循环的患者中经胸超声心动图(TTE)仅提示18例。患者冠状动脉均不同程度增宽,各组LCA、RCA近段直径分别为:年龄≤1岁组LCA 2.1~3.7mm,RCA 3.0~3.7mm;1~7岁组LCA 2.1~4.0mm,RCA 3.2~5.2mm;>7岁组LCA 5.0~9.5mm,RCA 5.2~9.0mm。22例患者行冠状动脉重建术,除1例失访外全部存活。结论:DSCT可明确诊断ACAPA,并可以为手术方案的制定和预后评估提供依据。
Objective:To investigate the value of dual-source computed tomography (DSCT) for diagnosis of anomalous origin of the coronary artery from the pulmonary artery (ACAPA). Methods: A retrospective analysis of DSCT images, clinical data,and followed-up was performed in 27 patients with ACAPA. Results: Of the 27 patients with ACAPA, 24 had anomalous origin of the left coronary artery (LCA) ,and 3 cases had anomalous origin of the right coronary artery (RCA). Twenty cases were found numeral collaterals by DSCT,however, only 18 cases were found by TTE. All LCA and RCA were dilated,the mean diameter of proximal LCA and proximal RCA were as follows:age 41 year subgroup,LCA 2.1-3.7mm, RCA 3.0-3.7mm;age 1-7 years subgroup,LCA 2. 1-4.0mm,RCA 3.2-5.2mm;age〉7 years subgroup,LCA 5.0- 9.5mm,RCA 5.2 - 9.0ram respectively. Twenty-two cases accepted coronary artery revascularization procedure, 21 cases survived,with the exception of one case lost follow-up. Conclusion: DSCT can detect ACAPA, and provide information for surgical plan and prognosis of ACAPA.
