This Prospective study will be conducted To copare uterine blood flow using Doppler ultrasound before and after evacuation of hydatiform mole between female patients with remissions and those with development of post-molar persistent gestational trophoblastic neoplasia to detect accuracy,efficacy,predictive value and acceptability of uterine artery doppler in predicting gestional trophoblastic neoplasia .
Patients with confirmed diagnosis of complete hydatiform mole.
Hemodynamically stable patient .
No contraindication for anesthetic materials used for the evacuation .
Acceptance of possible prolonged follow up , repeated uterine artery doppler ultrasound ,repeated HCG tests
Patient refusal to participate in the study.
Patient with incomplete hydatiform mole .
Patients who were lost during the follow-up period after this procedure.
Contraindication for anesthetic materials used for the evacuation .
Female 18:45 years with complete hydatiform mole
Cohort
Prospective
Not listed
Uterine artery Doppler flow velocimetry
First the patient will evaluate the urinary bladder Positioning of patient:supine position Amidsagittal section of uterus and cervical canal is obtained and the transducer is moved laterally untill the paracervical vessels are visualized color flow doppler is applied the uterine arteriesare seen as aliasing vessels along the side of the cervix Uterine artery doppler indices will be measured PSV=peak systolic velocity EDV=end diastolic velocity TAMV=time average medium velocity P.I(pulsatile index)=PSV-EDV/TAMV R.I(resistance index)=(PSV-EDV)/PSV SD(systolic diastolic ratio)=PSV/EDF
