非器质性三尖瓣中重度反流的产前病因诊断及预后分析

目的探讨非器质性三尖瓣中重度反流的产前病因并评价预后。方法回顾性分析非器质性三尖瓣中重度反流胎儿63例,(1)总结反流病因;(2)对比产前产后反流程度变化。结果 (1)63例胎儿中,单纯三尖瓣反流28例,动脉导管提前收缩及早闭18例,卵圆孔血流受限及早闭12例,永存左上腔静脉1例,双胎输血综合征3例,胎盘绒毛膜血管瘤1例;(2)生后随访示除2例胎儿反流程度未恢复外,其余胎儿均恢复至轻度或轻度以下。结论非器质性三尖瓣反流胎儿,出生后大多数反流恢复,预后较好。

Prenatal Diagnosis and Prognosis of Moderate to Severe Non-organic Tricuspid Regurgitation

Objective To investigate the etiology and prognosis in fetuses with moderate to severe non-organic tricuspid regurgitation. Methods A retrospective analysis of 63 cases of non-organic tricuspid mid-to-severe regurgitation fetuses,(1) To conclude the reasons.(2) To observe the change between prenatal and postnatal. Results(1) Of the 63 cases, 28 cases were simple regurgitation, 18 with premature constriction or complete closure of fetal ductus arteriosus,12 were restriction or closure of foramen ovale, 1 with persistent 1 eft superior vena cava,3 with twin-twin transfusion syndrome and 1 with placental chorioangioma.(2) Follow-up showed that excepted for 2 fetuses,the regurgitation degree of other fetuses recovered to mild or below. Conclusions Most of the non-organic tricuspid regurgitation fetuses recovered after birth.
