Serious and deadly complications from pregnancy after endometrial ablation: two case reports and review of the literature

Endometrial ablation (EA) has been performed for the past two decades as an alternative to hysterectomy in women with dysfunctional-uterine bleeding unresponsive to medical treatment. However, unlike hysterectomy, this minimally invasive procedure is not an effective means of contraception. Pregnancy following EA has been reported, but the risks and complications related have not been emphasized. This is a report on two such cases and review of the literature, with a closer look at the frequent negative outcome. A 25-year-old woman underwent EA for dysfunctional-uterine bleeding unresponsive to medical treatment. She had no previous surgery, specifically she had no past myomectomy or caesarean section. She declined concomitant tubal ligation. She became pregnant five years later in early spring 2007 and sustained a large uterine rupture at 24 weeks and died in June 2007 secondary to massive internal bleeding at age 29. A 34-year-old woman with previous hysteroscopic EA became pregnant less than one year after surgery. At that time, she had refused concomitant tubal sterilization since her husband had a vasectomy. Unfortunately, the relationship ended soon after surgery and she had unprotected sexual intercourse with a new partner. Pregnancy termination was complicated by placenta increta, which required immediate abdominal hysterectomy. Pregnancy after EA is not a rare occurrence, regardless of which technique is used. Whether women choose to go on or terminate their pregnancy, this clinical situation can be associated with serious complications and even maternal death. Counselling about contraceptive options at the time of EA is paramount.
