Doença trofoblástica gestacional complicada por hemorragia
The role of surgery in the management of gestational trophoblastic neoplasia. Currently, with early diagnosis made by ultrasound, most patients are diagnosed while the disease is trofoblastic in the asymptomatic phase.
Although of limited clinical significance, micrometastases can be seen scattered diffusely throughout the lung parenchyma. Patients with more advanced disease can present with an enlarged uterus, with lobulated, heterogeneous contours, or a pelvic mass that extends to adjacent organs Trofoblastixa flow studies in GTN Color and spectral Doppler flow studies are used together with an ultrasound gray scale in the assessment of GTN trofoblstica in its post-treatment follow-up There are three basic forms of radiological presentation of metastatic pulmonary GTN: In complicated cases, MRI is used as an ancillary method to assess the extent of the tumor.
Two years after the episode, the patient achieved a new, normal pregnancy. Studies have shown that nodules can persist after effective chemotherapy, without affecting the prognosis An MRI scan of a hydatidiform mole obtained during the first trimester shows little or no abnormality.
Diagnosis, classification and treatment ttrofoblastica gestational trophoblastic neoplasia.
Doenca Trofoblastica Gestacional
These lesions appear late in the course of the disease and are related to poor prognosis. Definitive sustained remission was obtained after chemotherapy. Imaging practices in trofoblawtica diagnosis and management of gestational trophoblastic disease: Vascular malformations can be detected years after treatment 2. Complete hydatidiform mole originates from the fertilization of an oocyte without maternal chromosomes by a haploid sperm with subsequent duplication of paternal DNA, giving rise to an egg gestacoinal exclusively parthenogenetic origin, with a diploid 46,XX karyotype.
The treatment is the same as that used in tubal ectopic pregnancy, and the follow-up is similar to that required for intrauterine hydatidiform mole. Modares M, et al.

The vasculature has a chaotic appearance, with color distortion and vascular changes, due to arteriovenous communications and neovascularization of the myometrial mass Low risk of relapse after achieving undetectable HCG levels in women with complete molar pregnancy. Therefore, careful monitoring of hCG and contraception are essential. Another use of conventional angiography is in the management of cases of uterine arteriovenous malformations after GTN in patients who are symptomatic and wish to conceive, given that selective embolization of such malformations, via the uterine artery, has provided auspicious results.
It is usually accompanied by malformation of the gestational sac or of the fetus, which can have characteristics such as hydrocephalus, syndactyly, cleft lip, and growth restriction In the hypervascular form, the tumor has an isointense signal on T1-weighted images, a slightly hyperintense signal on T2-weighted images, and avid uptake after the administration of contrast gadolinium. Human chorionic gonadotropin follow-up in patients with molar pregnancy: One of the most common treatment regimens is the combination of etoposide, methotrexate, and actinomycin-D, alternating weekly with cyclophosphamide plus vincristine Because PSTT and ETT respond poorly to chemotherapy, they should be treated with chemotherapy and hysterectomy, sometimes including pelvic lymphadenectomy Through the use of MRI, the location, vasculature, and extent of the tumor can be evaluated with greater accuracy.
MRI scan of the brain, showing a mass suggestive of metastatic choriocarcinoma, in a 32 year-old patient presenting with headache, speech articulation disorder, and dysphagia. Royal College of Obstetricians and Gynaecologists; [cited Nov 12]. These classic vesicular lesions, the aspect of which has been described as “snow storm”, “bunch of grapes”, or “granular”, range from 1 mm to 30 mm in size and represent the hyperplastic and hydropic villi seen on transvaginal ultrasound during the first trimester Figure 1.
Transvaginal ultrasound in a patient with bleeding at 14 weeks of pregnancy, showing an enlarged uterus with gestaconal endometrial cavity filled with amorphous material with multiple anechoic areas, suggestive of complete hydatidiform mole. However, if metastasis is detected, the focus shifts to choriocarcinoma. Utility of commonly used commercial human chorionic gonadotropin immunoassays in the diagnosis and management of trophoblastic diseases.
Transvaginal ultrasound showing an embryo and a deciduous area filled with anechoic images suggestive of partial hydatidiform mole. In such cases, partial hydatidiform mole with trisomy is differentiated by identifying a separate, normal, placenta 1,2, Contrast-enhanced T1-weighted images can show a mass with a signal equal to or slightly more intense than that of the adjacent myometrium, containing small, distributed diffusely cystic spaces, reflecting the vesicular nature of the tumor Partial hydatidiform mole presents as thickened placental tissue containing various anechoic cystic lesions 31and some cases can present amniotic membranes and a functional umbilical circulation, as depicted in Figure 3 Belfort P, Braga A.
If there is liver involvement, the lesions are usually multiple, heterogeneous, and hypointense, with a high avidity for intravenous contrast in the arterial phase Figure 9and hemorrhagic transformation is common. Current FIGO staging for cancer of the vagina, fallopian tube, ovary, and gestational trophoblastic neoplasia.
Doppler flow studies can also be used to evaluate the response to chemotherapy. Note the presence of hypoechoic areas in the myometrium, resembling the hypervascular “Swiss cheese” aspect, suggestive of an invasive mole, on the Doppler flow study.
After being diagnosed, patients with GTD should be evaluated at a referral center for its treatment, where the uterine contents can be evacuated by vacuum aspiration 1,2.
