So I was watching an interventional radiology uterine artery embolization procedure on a website. I understand the theory: embolize the uterine artery to block blood flow to the uterine fibroid. But then the doc said that the embolization wouldn't affect the uterus because it has lots of collateral circulation. So if the uterus has collateral circulation, doesn't that mean the fibroid would get collateral circulation as well? What's so good about this procedure vs hysterectomy anyway? Does it allow the patient to bear children? As I understand it, you can perform a hysterctomy and still retain the ovaries, so the pt won't have to take hormones. Also, what are some of the most common interventional radiology procedures? any particularly interesting ones? A GS resident once told me that IR docs perforate during their procedures all the time and GS has to come in and clean up the mess. How true is that? Thanks!!
