There are a couple of reasons for this. First, interventional radiologic treatments are not widely known not only to to patients but also to many doctors. Likewise, UFE is not sufficiently and correctly known to doctors including gynecologists. For this reason, most fibroid patients are not informed on UFE by gynecologists, and not referred to interventional radiologists. Second, the number of interventional radiologists in the world is not enough for the big potential of these treatments and only a small part of these doctors have sufficient knowledge and experience in UFE. And third, the equipment such as a digital angiography device and staff are not everywhere available.
However, despite these negative factors, UFE is increasingly known to doctors and patients. The number of IRs who can perform UFE is also rapidly increasing. As a result, UFE is more and more frequently used in the treatment of uterine fibroids.
