Arterial embolization of uterine fibroids and adenomyosis has become an effective treatment alternative to traditional methods, but the damage to the ovaries from embolization has always been a concern. Although worldwide statistics on ovarian damage after embolization have found that the incidence is not high, it is still a psychological burden for patients and a major test for physicians who are new to the procedure. How to prevent ovarian damage during uterine artery embolization is a problem that every interventional surgeon is bound to encounter. Combining my experience in this procedure with my personal experience, I would like to propose the following points to help prevent ovarian damage. 1, when uterine arteriography, use low flow rate and high volume contrast conditions to fully display the uterus and its branches to clarify the overall as well as ovarian situation for the next embolization; 2, when uterine arteriography, use contralateral plus foot side projection position to help show the blood supply of ovarian branches and ovaries; 3, use absorbable materials during embolization, not oil (because it is very easy to have ovarian embolization); 4. During embolization, pay attention to the density and amount of embolic material, and the control of the “degree” of embolization is the key; 5, pay attention to the flow direction of embolic material during embolization, once the flow of the ovarian branch appears, it must be stopped immediately; 6, because the degree of embolization and the efficacy of the effect of correlation, but the degree of embolization and ovarian damage into a correlation, so it is necessary to The operator needs to have a better control between efficacy and complications.
