Obstetric complications in women who underwent conservative myomectomy before pregnancy

Abstract

The article presents a literature review devoted to the obstetric complications in pregnant women after conservative myomectomy. The attention is paid to such a complication as uterine rupture. The authors consider impractical to evaluate the uterine scar before pregnancy using ultrasound methods and hysteroscopy.Uterine rupture of any type should be documented in the medical history (published), which allows the clinicians and women to better understand factors associated with the risk for rupture and to inform the patient’s decision to deliver by cesarean section or through the vagina.A review and analysis of a case of uterine rupture in a patient after conservative myomectomy is also performed. A 40-weeks pregnant woman was taken to the operating room 12 hours after the start of the acute uterine rupture clinic and decrease of hemodynamic parameters. About 2 liters of blood was found in the abdominal cavity, and a tear up to 7 cm long was determined in the area of the uterine fundus, closer to the left uterine angle. In the female outpatient consultation, during the observation of a pregnant woman who had the laparoscopic intervention – myomectomy, a diagnosis of “scar on the uterus” was not established. Medical documentation providing information on prior surgery was ignored and was not required. During the observation of the pregnant woman, the method of childbirth was not considered by the doctor’s council, and prenatal hospitalization was not performed.By studying the modern scientific sources, there is very little data about factors what increase the risk of uterine rupture, such as penetration into the uterine cavity. Performance of laparoscopic intervention, as a rule, is associated with the implementation of reproductive function in the future. Obstetricians and gynecologists who perform surgical intervention should describe the operation protocol not formally, but taking into account the implementation of the reproductive function. For many women after myomectomy, vaginal delivery can be a safe and feasible option, with patient choice and informed consent regarding the mode of delivery is important. Women should be offered choice and provided with appropriate counseling using all available evidence and monitored during pregnancy and birth in health care institutions that support their choice. This article provides practical recommendations for the management of pregnancy and childbirth in patients who had conservative myomectomy.
