Pelvic angiography (PAG) by Seldinger is one of the most useful examinations for the diagnosis of trophoblastic disease and also for the assessment of the therapeutic results. This technique, however, causes some stress to the patient. Therefore, noninvasive method, such as computed tomography (CT) and ultrasonography (USG) have recently been introduced. In the 1980s, digital subtraction angiography (DSA) was developed. It is now being used increasingly in the fields of Obstetrics and Gynecology as a substitute for the conventional PAG.<BR>In this report, the results of DSA, PAG, CT and USG which were carried out before and after chemotherapy in a patient with invasive hydatidiform mole were compared. In terms of the location, size and shape of the lesion, the CT findings were almost the same as those of USG. In terms of the angiographic findings in the affected area, intravenous DSA (IVDSA) was a sufficiently substitutional examination for conventional PAG.<BR>With IVDSA, arterial images can be obtained following the intravenous injection of a contrast medium. Therefore, this technique is excellent in terms of simplicity and safety. From now on, DSA will be utilized instead of PAG as an effective diagnostic method for trophoblastic disease and for follow-up such cases.
