2024年3月22日 · Gestational trophoblastic disease (GTD) results from the abnormal proliferation of trophoblastic tissue and encompasses a wide spectrum of diseases, including 14: tumor-like lesions. exaggerated placental site reaction. placental site nodule and plaque. abnormal (non-molar) villous lesions. molar pregnancies. partial hydatidiform mole. complete ...

2017年6月4日 · Ultrasound findings show a live fetus with either a single enlarged placenta with the classic cystic changes and increased echoes or there may be two placentas, one normal and one molar (Fig. 18.5). Ultrasound is also critical in the ongoing management of these pregnancies to help ensure the well-being of the coexisting fetus.

Doppler ultrasound has several applications in evaluating patients with gestational trophoblastic disease. Its role in differentiating the type of molar pregnancy and predicting trophoblastic neoplasia might aid clinicians in the management and counseling of patients.

2019年7月7日 · Gestational trophoblastic disease refers to a spectrum of disorders that results from abnormal proliferation of the trophoblastic epithelium. These include premalignant disorders (hydatidiform moles) and malignant ones (persistent/invasive gestational trophoblastic neoplasia, placental site trophoblastic tumors, epithelioid trophoblastic tumors ...

2017年3月13日 · Ultrasonography (US) is the modality of choice for initial diagnosis of complete hydatidiform mole and can provide an invaluable means of local surveillance after treatment.

Transvaginal ultrasound (also called ultrasonography): This ultrasound test uses a small instrument, called a transducer, that is placed in the vagina to look at the uterus and nearby tissue. Blood tests: Doctors use blood samples to check the levels of certain hormones and other substances that may be impacted by the presence of GTD.

2023年4月14日 · Overall, ultrasound is 34–57% sensitive in diagnosing molar pregnancy in the first trimester. The use of transvaginal ultrasound and color Doppler enhances the ability to assess the presence and extent of intrauterine disease in patients with GTN.

2012年1月1日 · Ultrasound is the initial imaging investigation of choice when gestational trophoblastic disease is suspected. Complete hydatiform mole, the most common form of molar pregnancy, usually has a characteristic “cluster of grapes” appearance, especially on second-trimester ultrasounds.

The aim of this essay is to summarize the most recent data on the ultrasound and Doppler findings of GTD and to provide a pictorial overview, including useful prognostic and therapeutic implications for clinical practice.

Ultrasound imaging has become standard protocol in aiding in diagnosis of vaginal bleeding and suspected GTD. Standard B-mode ultrasound is useful in detecting the presence of fetal pole and abnormal uterine masses, while color and pulsed Doppler sonography is effective in assessing blood flow through the uterine vasculature.
