Mrs. S aged 31 years, approached our center for secondary infertility. She had been married for 6 years. She had undergone three 1st trimester spontaneous abortions, for which evacuation had been done all the 3 times. Her menstrual cycles were regular and normal. There was nothing significant in her past or family history. There were no male factor problems as evidenced by a clinical and laboratory examination.
Mrs. S underwent investigations, which revealed the following: Hormonal profile was normal. Tests for antiphospholipid antibodies were negative. She was not a diabetic. We do not do TORCH tests as routine.
A pelvic ultrasound revealed multiple fibroids in the uterus, and an endometriotic cyst in the right ovary measuring 3 cms. On scan 6 fibroids were seen, all of which were more than 2 cms. The fibroids were located in the fundus, posterior wall, and anteriorly impinging on the uterine cavity.
Patient was counseled to undergo an operative laparosocpy and a hysteroscopy, to which she consented. A 3 cms submucous fibroid was removed via the hysteroscope. At laparoscopy 4 intramural fibroids, one anterior and three posterior were enucleated. The chocolate cyst in the right ovary was drained. Pelvic adhesions were released. Patient did well postoperatvely. She received 3 doses of Zoladex postoperatively at monthly intervals.
After this patient underwent ovulation induction with CC+HMG which was followed by intrauterine insemination at the appropriate time. She conceived in the first cycle of IUI. She is in the 9th month of her pregnancy. Her antenatal period has been uneventful. She is carrying a live normal single fetus.
Recurrent spontaneous abortion (RSA) has many causes, one of which is anatomical i.e. uterine fibroids. The role of fibroids in infertility is not clear. Many women with fibroids have normal fertility and pregnancies with no complications. Spontaneous abortion related to a fibroid may be due to the following.
-
Submucous fibroid may be a barrier to implantation or may occupy space in the uterine cavity.
-
An intramural fibroid may interfere with the blood supply to an embryo implanting near it.
-
A large sub serous fibroid may undergo degeneration or become infected. These may result in uterine irritability, uterine contractions, and a possible pregnancy loss.
Treatment may be indicated if:
In the above patient since all other investigations were normal, it seemed logical to postulate the fibroids as a probable cause for the RSA. Hence a myomectomy was decided upon. Laparoscopy myomectomy was the option. The cavity was not entered into, during the laparocopic procedure. The chocolate cyst was also removed. Patents first line of treatment was ovulation induction with intrauterine insemination. Fortunately she conceived in the first cycle. |
