[Intra-uterine arteriovenous malformations]

Intra-uterine arteriovenous malformations are a possible etiology of persistent metrorrhagia especially in the event of a history of miscarriages, cornuale pregnancy, molar pregnancy or gravidic trophoblastic diseases. We report 4 cases of patients having an intra-uterine arteriovenous malformation. The diagnosis of such lesions calls upon first intention Doppler echography. This diagnosis is confirmed thereafter by angiography. The first intention treatment is embolization which can save time if carried out at the same time as the angiography. This treatment is rapid and final, enabling the patients to have other pregnancies later on. An echographic follow-up, according to a schedule which remains to be defined, is necessary in order to check the good involution of this type of vascular malformation.
