腹部和阴道超声诊断宫腔内部分妊娠组织残留(附40例分析)

DIAGNOSIS OF RESIDUAL PLACENTAL TISSUE IN UTERUS WITH TRANSABDOMINAL AND TRANSVAGINAL ULTRASONOGRAPHY

本文分析了经腹部超声(TAS)和经阴道超声(TVS)检查40例宫腔内部分妊娠组织残留的声象表现。经病理证实诊断的符合率,TAS为87.5％,TVS为100％。残留组织的主要声象表现是以官腔内密集的强回声光团为主,伴少量宫腔积液。由于绒毛持续存在,血中促绒毛膜性腺激素(β-hCG)可保持较高水平,致使卵巢黄体囊肿不消退。高频率阴道探头检查可获得更清晰的宫内超声图象,对残留组织的检出率明显高于TAS检查,还有利于检出子宫内膜息肉和粘膜下子宫肌瘤。

Forty cases of residual placental tissue in uterus were diagnosed with transabdominal sonography (TAS) or transvaginal sonography (TVS) from Jan 1990 to Feb 1991. The accurate rate was 87.5% with TAS and 100% with TVS. The characteristic sonographic features of residual tissue were high level echo and slight fluid in uterus. Persistent ovarian carpus luteum cyst was found in some cases owing to high level beta hCG in blood.Transvaginal probe with high ultrasound frequency was helpful in diagnosing uterine residual placental tissue and in differentiating residual placental tissue from uterine submueous polyps or myoma.
