目的探讨彩色多普勒超声诊断胎儿永存左上腔静脉(PLSVC)及相关畸形的临床意义。方法回顾性分析13例PLSVC的产前胎儿超声及产后超声心动图资料或尸检病理资料。结果 13例PLSVC中,6例为单纯性PLSVC,7例合并心内畸形,5例合并心外畸形。在心内、外畸形的诊断中,漏诊3例,误诊1例。结论产前应用彩色多普勒超声提示胎儿PLSVC及合并心内、外畸形,可为胎儿预后评估提供可靠的依据,因此具有十分重要的临床意义。
Objective To investigate the clinical significance of color Doppler ultrasound in diagnosing fetal left temporoparietal vena cava (PLSVC) and related deformities. Methods Retrospective analysis of 13 cases of PLSVC prenatal fetal ultrasound and postpartum echocardiography or autopsy pathological data. Results Of the 13 PLSVC cases, 6 were simple PLSVC, 7 were with intracardiac deformity and 5 were with extracardiac deformity. In the heart, outside the diagnosis of deformity, missed diagnosis in 3 cases, 1 case of misdiagnosis. Conclusions Prenatal application of color Doppler ultrasound in fetal Fetal PLSVC and combined intracardiac and external deformity may provide a reliable basis for fetal prognosis evaluation. Therefore, it has very important clinical significance.
