| 目的 探讨MDCT诊断右心室双出口（DORV）的价值。方法 回顾性分析经手术或心血管造影确诊的36例DORV患者的临床及影像资料，将术前MDCT和超声心动图结果与手术结果进行对比。结果 MDCT明确诊断34例，误诊2例，诊断正确率为94.44%（34/36），超声心动图诊断正确率为75.00%（27/36），差异有统计学意义（P=0.022）。对判断室间隔缺损（VSD）与大动脉关系及大动脉位置关系，MDCT正确率均为100%（36/36），超声心动图诊断准确率为80.56%（29/36），差异有统计学意义（P=0.017）。共合并心内外畸形119处，MDCT与超声心动图对心内畸形检出率差异无统计学意义（P=0.474）；MDCT对心外畸形的检出率[98.72%（77/78）]高于超声心动图[69.23%（54/78），P<0.001]。结论 MDCT可准确诊断DORV、准确检出合并畸形，对制定外科手术方案具有重要参考价值。 |

| Objective To observe the value of MDCT in diagnosis of double outlet right ventricle (DORV). Methods Clinical and imaging data of 36 patients with DORV confirmed with operation or cardioangiography were retrospectively analyzed. The preoperative results of MDCT and echocardiography (Echo) were compared with surgical findings. Results MDCT definitely diagnosed 34 patients with DORV, while 2 patients were misdiagnosed, and the accurate diagnostic rate was 94.44% (34/36).The accurate diagnostic rate of Echo was 75.00% (27/36), and the difference was statistically significant (P=0.022). Moreover, in the relationship of ventricular septal defect (VSD) with large artery and the special relationship of the large artery in DORV, the diagnostic accuracy of MDCT was 100% (36/36), of Echo was 80.56% (29/36), and the difference was statistically significant (P=0.017). For totally 119 intracardiac and extracardiac malformations in all 36 patients, no significant statistical difference of diagnostic accuracy for detecting intracardiac malformation was found between MDCT and Echo (P=0.474), whereas for extracardiac malformations, the diagnostic accuracy of MDCT (98.72%[77/78]) was higher than that of Echo (69.23%[54/78], P<0.001). Conclusion MDCT could diagnose DORV and combined malformation definitely, therefore providing important guidance for surgical planning. |
