【摘要】：目的:探討雙源CT對右室雙出口(DORV)的診斷價值及對復(fù)雜先心病解剖畸形的確診價值。方法:回顧性分析17例經(jīng)雙源CT診斷并經(jīng)心血管造影、手術(shù)等確認為右室雙出口的病例資料。通過節(jié)段分析法分析內(nèi)臟-心房關(guān)系、心房-心室連接、心室-大血管連接等內(nèi)容,對DORV進行分型并確定解剖畸形,并與超聲心動圖進行對比。結(jié)果:17例DORV均經(jīng)雙源CT正確診斷,超聲診斷正確14例。雙源CT和超聲對17例DORV分型分別為主動脈瓣下型10例、8例,肺動脈瓣下型4例、3例,雙動脈瓣下型1例、1例,遠離大動脈型2例、2例。雙源CT確診合并其他解剖畸形共15種47處,僅2處漏診,1例未房間隔缺損,1例未動脈導(dǎo)管未閉。11例患者接受17次手術(shù)或封堵術(shù)治療。結(jié)論:雙源CT能對右室雙出口準確診斷及分型,對外科手術(shù)具有重要指導(dǎo)價值。
[Abstract]:Objective: to evaluate the diagnostic value of dual source CT in double outlet of right ventricle (DORV) and the diagnostic value of complex congenital heart disease anatomic malformation. Methods: the data of 17 cases diagnosed by double source CT and confirmed as double outlet of right ventricle by cardiac angiography and operation were analyzed retrospectively. The relationship between internal organs and atrium, atrial ventricular connection and ventricular great vessel connection were analyzed by segmental analysis. DORV was classified and anatomic malformation was determined, and compared with echocardiography. Results all 17 cases of DORV were correctly diagnosed by dual source CT and 14 cases were diagnosed correctly by ultrasound. DORV of 17 cases were classified as subaortic type (n = 8), pulmonary subvalvular type (n = 4), subvalvular type (n = 1), and distant type (n = 2). There were 15 kinds and 47 sites of other anatomical deformities diagnosed by dual-source CT. Only 1 case of non-atrial septal defect and 1 case of patent ductus arteriosus were treated with 17 times of operation or closure. Conclusion: dual source CT can accurately diagnose and type double outlet of right ventricle, and has important guiding value for surgical operation.
