This study was undertaken to determine prognostic factors in pregnancies with a subchorionic echolucency.
One hundred twenty-nine pregnancies with a subchorionic echolucency detected by ultrasound in our unit were identified. Ultrasound reports were reviewed for subchorionic echolucency location, size, gestational age, amniotic fluid volume, and fetal abnormalities. Adverse outcomes evaluated were pregnancy loss before 24 or 37 weeks (PTD) and intrauterine growth restriction. Medical records were reviewed for antenatal complications and neonatal outcomes.
There were 7 (5.4%) pregnancy losses before 24 weeks and 24 (18.6%) pregnancies complicated by PTD. Of the 122 pregnancies reaching viability, those complicated by antepartum bleeding were more likely to deliver prematurely than those without bleeding, (26.6% vs 7.0%, P=.009). Maximum area of subchorionic echolucency, gestational age at subchorionic echolucency detection, amniocentesis, maternal age, and parity were not associated with PTD.
Patients with subchorionic echolucency appear to have a high incidence of PTD. Bleeding appears to be a reliable prognostic indicator.
本研究旨在确定绒毛膜下无回声区妊娠的预后因素。
确定了我院超声检查发现有绒毛膜下无回声区的129例妊娠。回顾超声报告，了解绒毛膜下无回声区的位置、大小、孕周、羊水量和胎儿异常情况。评估的不良结局为24周或37周前的妊娠丢失（早产）和宫内生长受限。查阅病历以了解产前并发症和新生儿结局。
24周前有7例（5.4%）妊娠丢失，24例（18.6%）妊娠并发早产。在122例存活的妊娠中，并发产前出血的妊娠比未出血的妊娠更易早产（26.6%对7.0%，P = 0.009）。绒毛膜下无回声区的最大面积、发现绒毛膜下无回声区时的孕周、羊水穿刺、产妇年龄和产次与早产无关。
绒毛膜下无回声区的患者早产发生率似乎较高。出血似乎是一个可靠的预后指标。
