title: [Clinical study of four cases with malignant gestation trophoblastic tumor after mifepristone abortion].
abstract: OBJECTIVE
  To describe the clinical characteristics of malignant gestational trophoblastic tumor after medical abortion used by mifepristone combined with misoprostol and its diagnosis and differential diagnosis from incomplete abortion.
  
  
  METHODS
  Four cases with malignant gestational trophoblast tumor after medical abortion were presented focusing on the clinical manifestation and the methods of diagnosis and differential diagnosis.
  
  
  RESULTS
  Irregular vaginal bleeding and abnormal high level of beta-human chorionic gonadotropin (hCG) in plasma were the common manifestation of the gestational trophoblast tumour and incomplete abortion after medical abortion. However, beta-hCG of the former after curettage was still higher by dynamic monitoring. Malignant gestational trophoblast tumor showed rich blood flow signal and low blood flow resistance index (RI, RI < 0.5) in uterus in color doppler echography, digital subtraction angiography (DSA) with abnormal enlargement of the arteria of uterine, arteriovenous fistula beside the uterine were the main characteristics of malignant gestational trophoblast tumour.
  
  
  CONCLUSIONS
  Pay attention to the early stage malignant gestational trophoblast tumour among patients with abnormal vaginal bleeding after medical abortion. beta-hCG and DSA were the most effective methods to diagnose and differentially diagnose choriocarcinoma from the incomplete abortion among the patients with abnormal vaginal bleeding after medical abortion.
