The Value of Utero-Ovarian Anastomosis in Uterine Artery Embolization is Still Controversial

To the Editor,
I read the paper by Sheikh et al.  regarding the angiographic detection of utero-ovarian anastomosis (UOA) and influence on ovarian function after uterine artery embolization (UAE) with great interest. The study found that UOA is more common than previously expected and patients with type Ib and type III anastomoses carry the risk of ovarian failure after UAE. Protective coiling seems to be an adequate strategy for avoiding ovarian failure in those types of anastomoses.
However, as far as we know, this conclusion still needs to be testified. The rate of UOA that can be displayed in this study was 97%, which is much higher than previous reports. In fact, many corpse studies have confirmed that UOA is 100% present [2, 3]. But unlike cadaveric studies, UOA is also affected by a variety of factors such as hemodynamics and contrast agent injection pressure during uterine angiography in vivo, which is the main reason for the large difference in UOA display rates in various...
