Uterine bleeding treatment. Coloured digital subtraction angiogram (DSA) of the pelvic region of a 45-year-old woman with menometrorrhagia, showing embolisation of the uterine arteries. Menometrorrhagia is a condition in which prolonged or excessive uterine bleeding occurs irregularly and more frequently than normal. Embolisation is a nonsurgical, minimally invasive procedure that involves the occlusion (blocking) of blood vessels by the introduction of emboli (blood clots).
