[Current state of uterine artery embolization for treating symptomatic leiomyomas of the uterus]

A number of new approaches in treating symptomatic leiomyomas of the Uterus have been introduced in recent years. Only little scientific data is available an percutaneous or laparoscopic myolysis using focussed ultrasound, laser, or coagulation guided by magnetic resonance imaging or an laparoscopic ligation of the uterine vessels by means of bipolar coagulation or clipping. Established therapeutic options are limited by a number of disadvantages, except for total laparoscopic hysterectomy with morcellation. The latter is a minimally invasive procedure that spares important pelvic structures and thereby reduces the risk of prolapse and is associated with rapid recovery of the patients. Another minimally invasive therapeutic approach with preservation of the uterus is transarterial catheter embolization of uterine leiomyomas in which the vessels supplying the leiomyomas, in particular the branches of the uterine artery, are partly occluded by injection of synthetic (polyvinyl) beads. Uterine artery embolization has since developed into a good alternative to other therapeutic options. Studies report cure rates ranging from 77-93 %.
