Bettencourt, EPinto, EAbraúl, EDinis, MOliveira, CF2008-11-242008-11-241997Eur J Gynaecol Oncol. 1997;18(6):461-4.http://hdl.handle.net/10400.4/118The clinical, transvaginal sonography and colour flow mapping of one patient with placental site trophoblastic tumour is presented. Colour Doppler documented a marked increase in uterine vascularity, characterised by low diastolic flow suggestive of low resistance blood flow, without regression after completion of apparently successful chemotherapy, when negative beta-hCG plasma levels were obtained. Surgical treatment was based upon our experience with colour Doppler assessment of gestational trophoblastic tumours and a review of the literature. This case suggests that TV-CDS, performed serially, is very useful in monitoring patients during chemotherapy and in detecting residual tumour, and should greatly increase the accurancy of diagnosis of PSTT.engTumor Trofoblástico de Localização PlacentáriaUltrassonografia Doppler a CoresUltrassonografia Doppler de Pulsojournal article
