Mirena Migration Requires Surgery to Correct

Posted in Mirena

It has recently been found that an intrauterine contraceptive device (IUD) marketed under the brand name Mirena® may move (migrate) from its original location, possibly causing a variety of problems and requiring surgery to remove the IUD.

An article published in a 2011 edition of the Journal of the Society of Laproendoscopic Surgeons by Dr. Mark Erian et al., reviews two cases in which a Mirena® IUD migrated outside of the uterus.  In one woman, the IUD migrated to “[the back surface of the abdomen] just [in front of] the cecum,”[1] a sac marking the beginning of the large intestine.  In the second case, the Mirena® IUD migrated through the abdominal cavity, “close to the left leaf of the diagram.”[2]

When these Mirena® IUDs migrate, the problems that ensue depend on the location to which the IUD has migrated, what, if any, damage was caused as the IUD moved, and finally, on the course required to remove the IUD.  If the surgery required to remove the device is invasive, the chance for infection and other issues is raised dramatically.

For these two women, thankfully, only a process called laparoscopic retrieval was required.  Laparoscopic retrieval is a surgical procedure in which a small incision is made in the abdomen and a laparoscope, a small camera, is inserted.  This allows a surgeon to see inside a body and perform surgery without requiring a large incision, allowing less chance for infection and a shorter recovery time.

In the first woman described by Erian et al., aged 44 years, a Mirena® IUD had been implanted for 15 months without problem,[3] until an ultrasound scan of the uterus during a routine cervical smear “confirmed that the device was not in the uterus.”[4]  To locate the missing IUD, a “computerized tomography scan,”[5] or three-dimensional X-ray, was used, confirming that the IUD was on the right side of the rear of the abdominal cavity, just in front of the cecum,[6] a sac that constitutes the beginning of the large intestine.

The laparoscope camera also revealed that the device had become adhered to the cecum and a fatty layer called the omentum,[7] requiring laparoscopic adhesiolysis to sever the IUD from the woman’s organs.  Fortunately, this procedure was uneventful, the device was removed successfully, and the woman was discharged healthy after the procedure.[8]

The second case described in the Erian et al. piece entails the migration of a Mirena® IUD in a 19-year-old woman.[9]  This woman had been using the Mirena® IUD since the time a pregnancy was voluntarily terminated, and after 10 days’ insertion,[10] the woman complained of “acute severe pelvic pain.”[11]  Ultrasound of the uterus showed that the uterine cavity was empty by that time.[12]

“Plain X-ray”[13] revealed that the IUD had migrated through the peritoneal cavity (abdomen) to just below the diaphragm.  Again, fortunately, the device was removed from this woman without complication, and she was discharged soon after surgery in good health.[14]

Discussing these two cases broadly, Erian et al. write that Mirena® is a generally effective product in terms of its contraceptive capacity, but note that the device has important side-effects.  “Continuing pain and discomfort as well as irregular vaginal bleeding”[15] are written to be common side-effects, and it is also noted that migration of the IUD and perforation (cutting) of the uterus are possible dangerous side effects of which patients should be warned before IUD use.[16]

Because Bayer Pharmaceuticals, the manufacturer of Mirena®, did not adequately warn patients and physicians of all of the dangers of its product, namely Mirena® migration, a number of Mirena® migration lawsuits are currently being filed.  If you or a loved one used Mirena® and experienced Mirena® migration or other negative Mirena® side-effects, you may be entitled to significant financial compensation for your injuries.
