鉴于滋养细胞是通过破坏子宫血管形成血液腔隙的特点,利用彩色多普勒超声对靶器官—子宫的血流进行研究是可行的。可利用经阴道彩色多普勒对子宫动脉血流的研究来确定该方法对早期鉴别良性葡萄胎和恶性妊娠滋养细胞疾病的有效性。 自1994年3月1日～1995年2月28日在某妇科医院肿瘤部就诊并通过超声检查确诊为妊娠滋养细胞疾病的32例病人分为两组:第1组全麻下行吸宫术后2周血β-hCG升高维持高水平而行化疗者
Since trophoblasts are characterized by vasoconstriction of uterine blood vessels, it is feasible to study the blood flow of the target organ, the uterus, using color Doppler ultrasound. Transvaginal color Doppler can be used to study the uterine artery blood flow to determine the effectiveness of this method for the early identification of benign and malignant gestational trophoblastic disease. From March 1, 1994 to February 28, 1995 in a gynecological hospital tumor department and diagnosed by ultrasound examination of gestational trophoblastic disease in 32 patients divided into two groups: Group 1 under anesthesia after aspiration Two weeks of blood β-hCG increased to maintain high levels of chemotherapy in those
