摘要
目的探讨不典型胎盘早剥超声声像图特点并分析漏诊原因。方法对19例不典型胎盘早剥患者行腹部彩色多普勒超声检查,观察胎盘内部回声、胎盘与子宫壁间的回声、彩色多普勒血流情况及胎盘厚径。结果 19例中超声检出胎盘球状增厚3例,胎盘与宫壁间无回声区3例,胎盘与宫壁间低回声7例,胎盘部分增厚2例,胎盘与宫壁间窄带状低回声、胎盘与宫壁间大范围低回声、胎盘均匀增厚、胎盘与宫壁间未见异常回声并且胎盘内未见明显异常回声各1例。其中18例行急诊剖宫产手术,孕妇及新生儿预后良好,1例漏诊,剖宫产后因重度新生儿窒息而死亡。结论不典型胎盘早剥患者的超声声像图表现复杂多样,需结合临床表现仔细甄别;超声显示胎盘与宫壁间小范围的无回声、低回声、胎盘部分增厚或均匀增厚、球状增厚等多为不典型胎盘早剥表现。
Objective To study the uhrasonographic appearances of atypical placental abrupture and analyze the reason of missed diagnosis. Methods Nineteen cases of atypical placental abrupture were scanned by transabdominal color Doppler ultrasonography to observate the echo of retroplacental and introplacental region, the color Doppler flow and the thickness of the placenta. Results The ultrasonographic appearances including three cases of focal thickening placenta, three cases of anechoic retroplacental region, seven cases of hypoechoie retro- placental region, two cases of partial thickening area and other appearances in narrowly hypoechoic, mixed hypoechoic, well-distributed thickening placenta and normally ultrasonographic appearances of retroplacental region and introplacental region. Eighteen cases were undergone caesarean section in emergency, one ease was misdiagnosed and the baby died due to severe asphyxia neonatorttm. Condusiorls Differential diagnosis should be done with clinical signs because of the complex ultrasonographic appearances of atypical placental abruption. The ultrasono-graphic appearances of atypical placental abrupture are mainly in small area of hypoecho, anecho, partial thickening placenta and well-distributed thickening placenta.
