双源CT 在评价成人先天性心脏病中的临床价值

摘要

目的：探讨双源CT （DSCT）在评价成人先天性心脏病（ACHD）中的临床价值。方法回顾性分析29例行DSCT检查的ACHD患者资料。结果29例患者中，多数合并两种以上畸形，其中，心内畸形20例，包括法洛四联症4例（13．79％），房间隔缺损6例（20．69％），主动脉瓣二叶畸形4例（13．79％），室间隔缺损8例（27．58％）；心外大血管畸形19例，包括主动脉缩窄3例（10．34％），动脉导管未闭4例（13．79％），大动脉转位3例，肺静脉异位引流5例（17．24％）。结论 DSC T不仅能清楚显示ACHD患者心脏大血管畸形，还能对患者双肺、气管及支气管进行观察，可以为手术提供详细的解剖学信息。%Objective To investigate the clinical value of dual‐source CT (DSCT ) in assessing adult congenital heart disease (ACHD) .Methods The data in 29 ACHD patients with DSCT were retrospectively analyzed .Results Among 29 cases ,the major‐ity suffered from two or more cardiovascular malformations ,in which 20 cases had intracardiac malformations ,including 4 cases (13 .79% ) tetralogy of Fallot ,6 cases (20 .69% ) were atrial septal defect ,4 cases(13 .79% ) were bicuspid aortic valve (13 .79% ) and 8 cases (27 .58% )were ventricular septal defect ;19 cases had extracardiac malformations ,in which 3 cases(10 .34% ) were co‐arctation of the aorta ,4 cases (13 .79% ) were patent ductus arteriosus ,3 cases (10 .34% ) were transposition of the great arteries and 5 cases (17 .24% ) were anomalous pulmonary venous connection .Conclusion DSCT could not only clearly demonstrate the cardiovascular malformations in ACHD patients ,but also conduct the observation on the lung ,trachea and bronchia ,which can pro‐vide detailed anatomic information for surgery .
