Background: The pregnancy rate in patients with incompetent uterine scar (isthmocele) ranges between 1/1800 and 1/2216, which makes up 6.1% of all pregnancies with a history of cesarean section. Isthmocele occurs in 70% of pregnant women who previously underwent uterine surgery and presents a high risk of uterine rupture. Metroplasty during pregnancy is a rare type of medical care that requires profound knowledge and experience in this area.
Case report: The article presents a clinical observation of a 33-year-old patient with a uterine scar in her second pregnancy after having a cesarean section 6 years before. The routine ultrasound examination revealed a 28.0×16.0×40.0 mm isthmocele at 19–20 weeks’ gestation, clinical symptoms were absent. After the patient was hospitalized, metroplasty was performed. The pregnancy was prolonged to 34 weeks due to the administered medications for the prevention of preterm birth. The thickness of the myometrium in the area of the scar was 2.0 mm. When there were complaints indicating the threat of the uterine rupture (pain in the lower abdomen, a decrease in the thickness of the myometrium to 1.8 mm), a cesarean section was performed. A live premature female infant was born weighing 1922 g, 47 cm long, with an Apgar score of 7–8 points. The wound on the uterus was closed with a double-row continuous polyglycolide suture, peritonization was not performed. The postoperative period was uneventful. The patient was discharged on the 3rd day after the operation. After 6 months, the ultrasound examination showed that the endometrium corresponded to the first phase of the cycle, the uterine scar along the anterior wall had no signs of incompetence and was more than 10 mm thick. The child’s development was age-appropriate.
Conclusion: Metroplasty for the incompetent uterine scar is a method of choice that makes possible to prolong a pregnancy and deliver a viable child at the time close to full-term.
