Some months ago, a fellow Asherman’s syndrome (AS) sufferer who writes the blog Alternative Asherman’s had a missed miscarriage after AS and wrote of her experience (Three steps backwards) using misoprostol, linking it to the blog about my own experience using misoprostol. I feel it is necessary to clarify certain points in her experience as they may be inadvertantly misleading and appear to implicate misoprostol in what apparently ensued. She has also since updated her blog to clarify her interpretation of her experience.
Misoprostol is a non-invasive uterotonic drug that expels the uterine contents in a way that is analogous to a natural miscarriage. Scarring and subsequent adhesions are the result of physical injury (or severe infection) to the basal endometrium. In fact management of miscarriage with misoprostol has been shown to prevent adhesion formation compared to blind D&C (Tam WH, Lau WC, Cheung LP, Yuen PM, Chung TK. J Am Assoc Gynecol Laparosc.2002; 9 (2): 182–185.). Misoprostol can be used to expel the contents of the uterus for either pregnancy termination, after a missed or incomplete miscarriage has occured or for labour induction. It also dilates the cervix and is useful prior to hysteroscopic surgery. Unfortunately, misoprostol is often referred to as a 'pregnancy termination drug' despite its various uses.
With regards to misoprostol's efficacy it should be noted that she obtained Chinese herbs from her accupuncturist to help 'prepare her body for miscarriage'. (See her comment below). This is unnecessary. It is not advised to mix Chinese or any other alternative or over the counter drug/herb with the treatment prescribed by your qualified ObGyn. Any responsible qualified homeopath/alternative medicine practitioner (some are MDs) would not dispense drugs whose effects and interactions with drugs prescribed by another specialist is not known and has not been vigorously trialed. There is no regulation or standardization of alternative drugs (herbs, extracts, etc.) so their concentrations, compositions quality and therefore effects and interactions vary greatly. We don't know if using these herbs could have interfered with misoprostol's effect in some way (for example, reducing its efficacy by blocking the same receptors targeted by misoprostol).
She was told that she developed IUA after using misoprostol and prior to hysteroscopic surgery to remove retained products. Her hysteroscopic surgeon said that the RPOC from an incomplete evacuation led to fibrous scar tissue formation. While I have heard about this anecdotally, I have not seen any reports of women developing IUA from RPOC in the absence of severe infection. It is also difficult to reconcile the observation of dense scar tissue with products retained for just 5 weeks when scar tissue is not complete until about 8 weeks. Anecdotally, I personally had substantial retained products for 3 weeks after my second trimester miscarriage treated with misoprostol and did not develop IUA. RPOC and retained placenta can be managed conservatively (under medical supervision).
However, she does mention that she may have already had some recurrence of IUA before her pregnancy as her Obstetrician noticed what appeared to be synechiae on ultrasound. This appears to be an important clue.
She says that there were dense adhesions whereas she previously had had only mild adhesions at initial diagnosis.One possible way to explain the deterioration of her condition could lie in the initial treatment of her AS: she had a uterine cook balloon inserted following adhesiolysis. While I underwent the same procedure without any apparent complications like hundreds of others (a proportion of whom have gone on to have children), it is possible that if the stent was not removed properly, or if it somehow adhered to raw surfaces in the uterus, it could have caused damage on removal (the balloon is deflated and simply pulled out). This explanation would also be consistent with her ObGyn's observation of scar tissue during a prenatal scan. Note also that there is limited data from studies on the benefits of using the Foley catheter and IUDs after surgical lysis and no controlled or comparative trials on the Cook balloon. Some Asherman’s syndrome specialists even believe that stents can stunt endometrial regrowth.
A well researched and routinely used drug like misoprostol should not be treated with suspicion compared to many other medical and even pseudo medical treatments the same women undergo without questioning, from unproven and potentially harmful altnernative drugs to contraversial fertility therapies to treatments of Asherman’s syndrome on which there are comparatively less data and of a lower quality. This leads me to wonder whether it is the attitude of the treating doctor(s) which influences patients' perceptions of treatments. I agree that more doctors need to be trained in the use of misoprostol for miscarriage (and in particular among women with a history of AS) and that a followup hysteroscopy may be needed depending on clinical symptoms and gestational age at time of miscarriage to ensure there are no retained products of conception. Followup hysteroscopy may also be necessary in women with a history of AS if the miscarriage passed naturally as there is a possible tendency towards retained tissue from scarring. We already know that women with past AS are at an increased risk of abnormally invasive placentation such as placenta accreta. Retained tissue and placenta accreta may be different ends of a spectrum of abnormalities associated with placental invasion in a defective endometrium. Whether misoprostol is necessary to evacuate miscarriages that occur very early on in the pregnancy (prior to 7 weeks) is also questionable. These can be managed expectantly. It is especially risky to perform a blind D&C in women who already have suffered damage to their uterine lining. It is time for miscarriage management as a whole to be reviewed in light of advances in medical therapy and hysterosopic alternatives.

Database of ObGyns who offer misoprostol for treatment of miscarriage
As I've mentioned before, in some countries there are not many ObGyns who offer misoprostol (Cytotec) for treating missed or incomplete miscarriages. This is unfortunate because it is known to be effective and does not carry the risks and potential complications such as infertility that standard care D&C does.
All women should be given a choice in the treatment of their own bodies, provided that their decision does not put their own life at risk.
Therefore I'm putting together a database of Obgyns from all over the world who do offer women the choice of medical management (eg. misoprostol/cytotec, mifepristone) so that women will have a resource if they find themselves in need.
If you are either a patient who has been treated with drugs for managing miscarriage, or a doctor who believes in a patient's right to choose and are experienced in the use of medical management of miscarriage, please contact me on:
ashermansprevention@gmail.com
Thank you.
Note to Doctors: Let me know if you have any concerns about having your names made public. I can always keep the database private and offer the names of doctors in specific areas confidentially to those who request it.

Miscarriage management after Asherman’s syndrome
Unfortunately, I can now talk from experience about how miscarriages can be dealt with post Asherman’s syndrome (AS), and what to expect. I lost my pregnancy at 14 weeks due to a trisomy 21 detected by karyotype analysis and QF-PCR of chorionic villi sampling. The first inkling that something was wrong was at the 12 week scan. Actually, the blood serum levels of PAPP-A and bHCG I’d had during the 11th week already showed a problem, but it wasn’t until my ultrasound that I learned of this. The ultrasound only confirmed that things were not right. Only two weeks earlier I’d had another ultrasound and all seemed fine- the heart beat, the CRL, etc. Now the nuchal fold measured 7mm and there was hydrops- an accumulation of fluid around the fetus. I was told there was a high probability that the pregnancy would end spontaneously.
Fast forward to week 14 and there was no longer a heartbeat.
I’d always talked about misoprostol and ironically now I would have to use it myself. There was no way on earth I’d undergo another D&C (suction curettage or whatever you want to called this blind invasive procedure)- the procedure which caused Asherman’s syndrome when I had it 3 years earlier for a blighted ovum. I could not risk exacerbating the condition. If only my initial ObGyn had agreed to treat me with misoprostol I could have avoided all the surgery and heart ache that followed. I’m quite sure I’d have a child by now.
Since I was relatively far into the pregnancy and the fetus had developed to 14 weeks before dying spontaneously, I booked in the hospital for the misoprostol induction. I don’t know which hospitals/ObGyns use misoprostol regularly, however, in the interest of informing women, my procedure was performed at the Royal Hospital for Women in Randwick (Sydney). I’m sure there are other hospitals (and doctors) that are familiar with misoprostol use, and yes, it is completely legal even if it has not been approved by the TGA (Australia's equivalent of the FDA) for gynecological indications for dubious reasons. By the way, the doctor who refused to give me misoprostol works at St George Hospital. I’d be interested to know if that hospital carries out medical management of miscarriage- please drop me a line or comment below if you know.
In total, I was given a dose of 1 mg (milligram) of misoprostol over the course of a day. Initially, one pill ie. 200 mcg (vaginal) was given to test for any adverse reactions, allergies etc. I began cramping but there was no bleeding. About 5 hours later cervical dilation was checked (closed) and I was given 400 mcg (2 pills). The cramping intensified, but again, there was no bleeding. Shortly after my third and final dose, about 5 hours after the last dose, I began having strong contractions. It was quite painful so I’d definitely recommend panadeine forte. Strangely, there was still no bleeding unlike with my first miscarriage which began like a period. About 40 minutes after my final dose, the waters broke and amniotic fluid spilled out soaking the bed. After this point the pain stopped although I was still feeling crampy for at least a week afterwards. Roughly half an hour after the waters broke, I delivered the tiny baby. The umbilical cord was thin and weak and broke off from the placenta. It is at this point that I began bleeding. I continued bleeding heavily throughout the night and the next day. I also bled strongly for about a week afterwards and on and off during the following week. The placenta should have come out soon afterwards but it was not until 3.5 hours passed that it did. Luckily I’d discussed the possibility of retained placenta previously with my ObGyn and we agreed to wait it out (normally most doctors would jump at the opportunity to do a D&C in this situation) while the nurses and midwives monitored me closely for signs of infection and hemorrhage. As it’s difficult to know if the placenta is complete on visual inspection, and women with a history of Asherman’s syndrome- even after surgical correction- are at an increased risk of placental conditions such as placenta accreta, percreta, increta, and previa, I knew retained placenta was a possibility.
Before the placenta delivered my temperature reached 40 C and the midwife was somewhat concerned, however misoprostol itself can cause fever. The morning after, my blood pressure was 90 on 60 (normally it is around 110-115/65-70) and I was told this could be due to blood loss.
The next morning I underwent an ultrasound to check for retained placental fragments. Around 32 mls of material was found in the uterus but it was impossible to tell whether this was simply blood and blood clots, or if there were retained products of conception (RPOC). Doppler flow analysis suggested that there were retained placental fragments in the posterior of the uterus- the same area where the placenta had implanted in this pregnancy. I had another ultrasound a week after the first. The second ultrasound showed that the fluid in the uterus had roughly halved, but it was still not possible to tell for sure via ultrasound whether there were retained products.
In the following week I bled little despite having around 18 mls of content in my uterus so I became concerned that perhaps there were retained fragments. This would not be a surprise given my pregnancy reached second trimester and my previous history of Asherman’s syndrome. I contacted my trusted Asherman’s syndrome specialist for a hysteroscopic procedure to remove any retained fragments of placenta. This procedure was done 3 weeks after the misoprostol treatment. It turns out I did have many retained fragments which were gently scraped off using the hysteroscope itself. Luckily I did not have any clinical infection from the retained tissue (perhaps just 'subclinical' ;) ?). There were no adhesions. I was given prophylactic antibiotics to prevent infection after the surgery.
I should also mention that to prevent any possible adhesions, I was prescribed 2mg/day progynova (a synthetic estrogen) for 28 days by an Asherman’s syndrome specialist. The other option was Premarin (0.625 mg). These help the endometrium grow and thereby prevent uterine walls from adhering in the case of scarring.
I’m now awaiting my next period after which I’ll have a mid cycle scan to measure endometrial thickness at ovulation, and either an in--office hysteroscopy or an HSG to check for adhesions. Hopefully the removal of RPOCs did not cause any scarring.
Note that the dose of misoprostol I was given was decided according to my pregnancy stage (14 weeks) and status (fetal demise). Doses vary and guidelines should be adhered to.
Here is a summary of my suggestions (as a non MD) if you find yourself in this situation:
1. Don’t have a D&C for a miscarriage as it can cause further damage especially if you have had AS previously. Also, your endometrium may get thinner each time you have a D&C.
2. Misoprostol helps clear out most of the uterine contents. It is more painful than a D&C but worth it in the long run- unless you are not interested in preserving your fertility. NOTE: If you have had a previous Cesarean section or uterine perforation or severe AS, discuss with your ObGyn to see if misoprostol is safe for you (or you may need to take a lower dose than what I was given).
3. You should have estrogen therapy to prevent adhesions from forming. I'm not sure if this is 100% necessary but Asherman's specialists recommend it. Some women didn't use it because of adverse reactions to estrogen (blood clots etc.) and they did not develop adhesions.
4. You will probably have retained tissue and require a hysteroscopy (not a blind D&C!!) to remove it. In most cases if you have had a missed miscarriage you will need to either use misoprostol or, alternatively, wait to miscarry before hysteroscopy can be effective, otherwise there is just too much tissue and blood to work with.
5. Have a mid cycle scan to measure endometrial thickness after your first post-treatment period and always check that your uterine cavity is free of adhesions before you attempt to conceive again just in case. An in-office hysteroscopy is best but failing that, an HSG can be done.
There are also some implications that can be speculated:
1. It may take a few hours for the placenta to deliver when using misoprostol post AS if you are beyond the first trimester.
2. It is likely that if you have had AS, you will have retained products after every future miscarriage. Hysteroscopic removal of tissue allows the doctor to view your uterus as he/she clears it. Note: Hysteroscopy itself can cause complications if undertaken by an unexperienced or unskilled doctor. Please see only a highly experienced specialist.
3. You should anticipate that you may have placenta accreta in a future pregnancy particularly if the placenta does not deliver when expected or you have had confirmed RPOC. Obviously, any woman with past AS should be monitored throughout their pregnancy by a high-risk Obstetrician.
I will try to write about the known pregnancy complications in women with a history of AS in the near future.
There are two more interesting points: Initially I believed that I may not get RPOC because the placenta had implanted in a region which was never affected by intrauterine adhesions. The fact that it is possible to get RPOC in a new, previously unaffected area suggests that perhaps the placenta implants deeply because the endometrium is slightly thinner than it should be ideally. Or maybe blood flow to the uterus is somehow affected and in order for the pregnancy to establish the placenta needs to invade the endometrium more deeply.
Secondly, I have to question once again whether there is any truth at all to the unfounded claim by certain doctors that Asherman’s syndrome can occur ‘spontaneously’ after miscarriage. I would have to have actual evidence to believe this. In my own case I had no adhesions 2 weeks after miscarrying using misoprostol-and this is even after having had intrauterine adhesions in the past (from a D&C). In other words they did not reoccur, nor did any new ones develop. I suspect that if I was treated with blind D&C rather than misoprostol, lo and behold I would develop ‘spontaneous’ adhesions in a new region: the posterior region of my uterus (where the RPOC were). It doesn't make sense for such an evolutionarily destructive mechanism to occur in nature (unless extremely rarely).
In retrospect, I have to wonder why my first Obgyn (ie the one who caused me to have AS) so steadfastly rejected my request to use misoprostol instead of a D&C when it can be used even until the third trimester. He made me believe that it could only be used until 8 or 10 weeks. I also wonder why, as a doctor who was aware about Asherman’s syndrome, my strong concern about acquiring it, and knew of the Asherman’s syndrome support group, he did not refer me for a hysteroscopic removal the supposed RPOC I had? What, may I ask, is the purpose of informing gynecologists about Asherman’s syndrome if they will continue to perform damaging D&Cs while refusing to offer other options? ‘Consent’ for D&Cs is hardly possible when other options are not made available. Please, let us not make Obstetricians/gynecolgists believe that treatment is so simple and effective that causing Asherman’s syndrome is just a little glitch with few consequences for the patient.
Finally, my experience has shown once again that prevention of Asherman’s syndrome is best: the condition leads to a cycle of costly and lengthy complications with retained products (not to mention possible obstetric complications in future pregnancies) which could be avoided if medical management (ie. misoprostol) was used in the first instance.
