摘要

目的：探讨胎儿心腔增大的非心脏结构病变因素及病变机制，为超声评价胎儿心腔增大提供筛查线索及合理的医疗干预依据。方法：对30例非心脏结构病变心腔增大胎儿（简称心脏增大组）的病因，进行超声随访、病理证实，并对比治疗前后胎儿血流动力学变化，分析胎儿心腔增大病理机制，明确超声检查线索。结果：心脏增大组原因分心外因素（20例）、心脏因素（7例）、不明原因（3例）。其血流参数：右室短轴缩短率（RVFS）、右室射血指数（RVEF）、大脑中动脉血流阻力指数（MCARI）、脐动脉血流阻力指数（UARI）与正常对照组比较有显著差异（P<0.01）。经母体常压氧疗法及口服强心药（简称期待疗法）治疗后，心脏增大组血流参数显著好转（P<0.01），分娩后86.7%（26/30）心功能正常。结论：胎儿非心脏结构病变心腔增大有一定规律可循，超声检查可明确病因，多属一过性心功能不良。

Abstract

Objective: To investigate the functional factors and mechanism of cardiac enlargement and the sonographic features beneficial for screening, clinical interventional treatment and follow up. Methods: There were significant differences in hemodynamic parameters including right ventricular short axis fiber shortening(RVFS), RV ejection fraction(RVEF), middle cerebral artery resistence index(MCARI) and umbilical artery(UA) RI between the study group and control group(30 cases), P<0.01. Result: After delivery, the cardiac function became normal in 86.7% infants. Conclusions: Fetal functional cardiac enlargement in some cases may be temporary; the reasons and factors can be found out on sonography.
