[Modification to surgical technique of cesarean hysterectomy].

Background: Bleeding is a significant cause of maternal mortality in the world. Obstetric hysterectomy increases maternal morbidity and mortality.

Objectives: To describe a modified technique of cesarean-hysterectomy to limit bleeding during surgery in cases of placenta accreta and placenta previa, which consist of hypogastric artery ligation before the removal of the uterus.

[Pregnancy and tetralogy of Fallot with and without surgical correction].
