A modified suture technique for the treatment of patients with pernicious placenta previa and placenta accreta spectrum: a case series

Sumario:BACKGROUND: Pernicious placenta previa complicated by placenta accreta spectrum (PAS) often leads to hysterectomy or even maternal death due to massive bleeding. In recent years, the application of balloons has received increasing attention. It is easier to use and has reasonably good effect. However, for some patients, especially those who still have some placental residue, there might still be active bleeding. To solve this problem, we propose a method of pressure sutures around the balloon to provide a better hemostasis effect. METHODS: An observational study was conducted on patients with pernicious placenta previa and PAS at the Beijing Chaoyang Hospital, Beijing, China, between January 2018 and January 2021. During surgery, an intrauterine balloon was used to compress the hemorrhage site, and two or more absorbable sutures were placed around the uterus to apply strong pressure on the balloon. This method is an updated modification of the Lu-suture which uses a Foley catheter balloon and only one suture. The main improvements include choosing different kinds of balloons depending on various conditions and the addition of a suture below the balloon to provide much stronger pressure and prevent the balloon slipping out through the dilated cervix. RESULTS: A total of 10 women underwent the procedure. The mean estimated intraoperative blood loss was 1,190±548 mL. Post-surgery, the blood loss was less than 200 mL in all patients. The mean blood transfusion [packed red blood cells (pRBC)] required was 2.2±2.6 units. The mean hemostatic time was 8.1±3.4 minutes. CONCLUSIONS: The modified suture technique provided an easy, cheap, and efficient surgical choice for patients with pernicious placenta previa and PAS.
