PLACENTAL SITE TROPHOBLASTIC TUMOR - THE VALUE OF TRANSVAGINAL COLOR AND PULSED DOPPLER SONOGRAPHY (TV-CDS) IN ITS DIAGNOSIS - CASE-REPORT

The clinical, transvaginal sonography and colour flow mapping of one p atient with placental site trophoblastic tumour is presented. Colour D oppler documented a marked increase in uterine vascularity, characteri sed by low diastolic flow suggestive of low resistance blood flow, wit hout regression after completion of apparently successful chemotherapy , when negative beta-hCG plasma levels were obtained. Surgical treatme nt was based upon our experience with colour Doppler assessment of ges tational trophoblastic rumours and a review of the literature. This ca se suggests that TV-CDS, performed serially, is very useful in monitor ing patients during chemotherapy and in detecting residual tumour, and should greatly increase the accurancy of diagnosis of PSTT.
