Another option is to see if a progestin-releasing intrauterine system (IUS) like the levonorgestrel (LNG) IUS would fit into this patient’s uterine cavity. Like Ted, I want to look into that cavity. I am not sure what “submucosal fibroid” means. If it has not distorted the cavity, or is totally within the uterine cavity, or abuts the endometrial cavity. The LNG-IUS cannot be placed into a uterine cavity that has intracavitary fibroids or sounds to greater than 12 cm. We are not going to put an LNG-IUS in somebody, at least in general, with a globally enlarged uterine cavity. I could ask, do you do that? You do a bimanual exam, and it is 18-weeks in size. I am not sure that I would put it in, but does it meet those criteria? The package insert for the LNG-IUS specifies upper and lower limits of uterine size for placement. I would start with those 2 options (tranexamic acid and LNG-IUS), and also get some more imaging.
Dr. Anderson: I agree with Linda. The submucosal fibroid could be contributing to this patient’s bleeding, but it is not the total contribution. The other fibroids may be completely irrelevant as far as her bleeding is concerned. We may need to deal with that one surgically, which we can do without a hysterectomy, most of the time.
I am a big fan of the LNG-IUS, it has been great in my experience. There are some other treatments available as well, such as gonadotropin–releasing hormone (GnRH) agonists. I tell patients that, while GnRH does work, it is not designed to be long-term therapy. If I have, for example, a 49-year-old patient, I just need to get her to menopause. Longer-term GnRH agonists might be a good option in this case. Otherwise, we could use short-term a GnRH agonist to stop the bleeding for a while so that we can reset the clock and get her started on something like levonorgestrel, tranexamic acid, or one of the other medical therapies. That may be a 2-step combination therapy.
Dr. Sanfilippo: There is a whole category of agents available—selective progesterone receptor modulators (SPRMs), pure progesterone receptor antagonists, ulipristal comes to mind. Clinicians need to know that options are available beyond birth control pills.
Dr. Anderson: As I tell patients, there are also “bridge” options. These are interventional procedures that are not hysterectomy, such as uterine fibroid embolization or endometrial ablation if bleeding is really the problem. We might consider a variety of different approaches. Obviously, we do not typically use fibroid embolization for submucosal fibroids, but it depends on how much of the fibroid is intracavitary and how big it is. Other options are a little more aggressive than medical therapy but they do not involve a hysterectomy.
Pros and cons of uterine artery embolization
Dr. Sanfilippo: If a woman desires future childbearing, is there a role for uterine artery embolization? How would you counsel her about the pros and cons?
Dr. Bradley: At the Cleveland Clinic, we generally do not offer uterine artery embolization if the patient wants a child. While it is an excellent method for treating heavy bleeding and bulk symptoms, the endometrium can be impacted. Patients can develop fistula, adhesions, or concentric narrowing, and changes in anti-Müllerian hormone levels, and there is potential for an Asherman-like syndrome and poor perfusion. I have many hysteroscopic images where the anterior wall of the uterus is nice and pink and the posterior wall is totally pale. The embolic microsphere particles can reach the endometrium—I have seen particles in the endometrium when doing a fibroid resection.
