【摘要】：目的探討二代雙源CT(Dual-source computed tomography,DSCT)在先天性三尖瓣畸形診斷中的應(yīng)用價值。方法回顧性搜集經(jīng)手術(shù)證實的40例三尖瓣畸形患者的DSCT及實時三維超聲心動圖(Real-time three-dimensional echocardiography,RT-3DE)診斷資料,比較DSCT掃描與RT-3DE診斷先天性三尖瓣畸形及其伴發(fā)畸形的結(jié)果符合率,采用卡方檢驗,P0.05為有統(tǒng)計學(xué)意義,并對三尖瓣瓣葉的圖像質(zhì)量進(jìn)行評分。結(jié)果 40例患者共計先天性三尖瓣畸形43處,有3例患者三尖瓣下移畸形合并三尖瓣發(fā)育不良,其中三尖瓣下移畸形32處,三尖瓣閉鎖3處,三尖瓣發(fā)育不良5處,三尖瓣瓣葉數(shù)目異常(二葉式畸形及瓣葉大部分缺如)3處。對于先天性三尖瓣畸形,DSCT和RT-3DE的診斷準(zhǔn)確率分別為90.70%(39/43),100%(43/43),兩者無統(tǒng)計學(xué)意義(χ~2=4.20,P0.05)。DSCT和RT-3DE對并發(fā)心內(nèi)畸形的診斷準(zhǔn)確率分別為82.86%(29/35)、100%(35/35),兩者有統(tǒng)計學(xué)差異(χ~2=6.56,P0.05);對并發(fā)心外畸形的診斷準(zhǔn)確率分別為94.12%(16/17)、58.82%(10/17),兩者有統(tǒng)計學(xué)差異(χ~2=5.89,P0.05)。40例患者DSCT三尖瓣圖像質(zhì)量評分為(3.82±0.73)分。結(jié)論 DSCT對于先天性三尖瓣畸形及其合并其他畸形的診斷具有重要的價值。
[Abstract]:Objective to evaluate the value of dual-generation CT(Dual-source computed tomphography (CT(Dual-source) in the diagnosis of congenital tricuspid valve malformation. Methods the diagnostic data of DSCT and real-time three-dimensional echocardiography (RT3DE) in 40 patients with tricuspid malformation proved by surgery were retrospectively collected. To compare the coincidence rate of DSCT scan and RT-3DE in the diagnosis of congenital tricuspid valve malformation and its concomitant malformation, the chi-square test was used as the statistical significance. Results there were 43 congenital tricuspid valve deformities in 40 patients, and 3 tricuspid valve deformities associated with tricuspid valve dysplasia, including 32 tricuspid valve deformities. Tricuspid valve atresia 3 sites, tricuspid valve dysplasia 5, The diagnostic accuracy of DSCT and RT-3DE for congenital tricuspid malformation was 90.70,39 / 43 / 100 / 43 / 43, respectively. There was no significant difference between DSCT and RT-3DE in the diagnosis of intracardiac malformation (蠂 ~ 24.20 / P 0.05. DSCT and RT-3DE). The accuracy rate was 82.86 / 35 / 100 / 35 / 35, respectively. There was a statistical difference between the two groups (蠂 ~ 2 / 6.56 / P 0.05), and the diagnostic accuracy of extracardiac malformation was 94.1212 / 17 / 58.822 / 1017%, respectively. There was a significant difference between the two groups (蠂 ~ (25.89) P 0.05 .40 cases with DSCT tricuspid valve image quality score was 3.82 鹵0.73). Conclusion the diagnostic accuracy of DSCT for congenital tricuspid malformation is 3.82 鹵0.73. The diagnosis of valve malformation and other deformities is of great value.
