Lower Uterine Segment Corrugated Sutures in Hemorrhage during Cesarean Section because Previal and/or Placenta Accreta Spectrum: Case Reports Series and Literature Review.

Objectives: We present the original technique of compression hemostatic sutures on the lower uterine segment due to early postpartum hemorrhage during cesarean section, with a literature review.

Methods: A retrospective clinical case study was conducted at the tertiary perinatal center. Twelve patients had nine planned and three urgent cesarean sections due to antenatally verified placenta previa and/or placenta accreta spectrum and defined early postpartum hemorrhage > 1000 mL during cesarean section. As the use of uterotonics failed to produce any effect and hemorrhage persisted, compression sutures of the lower uterine segment were made by our own technique, as follows: below the hysterotomy, a horizontal corrugated suture is placed from the right to the left corner and after 2-3 cm vertically and backwards at several sites from the left to the right corner, where it is tightened.

Results: Seven patients had one cesarean section, three patients had two cesarean sections, and seven patients had pregnancy from the in vitro fertilization procedure in their history. There were six patients with placenta previa and six patients with anterior invasive placenta accreta or increta. Original hemostatic procedure was applied successfully in ten cases, and after placement of O'Leary suture and persistent bleeding in two cases. In this group, no hysterectomy was performed, and patients received blood transfusion of 440-880 mL. Three patients later had spontaneous pregnancies.

Conclusion: Our own hemostatic method with a simple technique, fast learning, and minimal logistics contributes to successful management of this currently global problem of morbidly adherent placenta previa.
