Pregnancy after uterine artery embolization to control haemorrhage from gestational trophoblastic tumour.

Gestational trophoblastic tumour (GTT) of the uterus can cause severe and even life threatening haemorrhage in patients who may be contemplating future pregnancy. Three cases of successful pregnancy after uterine artery embolization to control severe haemorrhage from uterine GTT are reported. Both uterine arteries had been selectively catheterized and embolized in these patients. The areas of pathological circulation measured on the pre- and post-embolization films had been reduced by over 80%. Embolization failed to control haemorrhage in another four patients in whom the uterine arteries had not been selectively catheterized and embolized and where the embolization procedures had reduced the areas of pathological circulation by less than 65%. The conclusions are that control of severe haemorrhage from uterine GTT is likely if both uterine arteries are selectively catheterized and embolized. Patients thus treated can become pregnant.
