ObjectiveTo present a case series of 26 patients with postpartum hemorrhages treated with vascular ligations and analyze its efficiency for hemorrhagic control. Material and methodsThis case series included patients with postpartum hemorrhages hospitalized in a high risk pregnancy unit in Sofia Feldman Hospital, Brazil, between January 2014 and May 2017, who were treated with vascular ligation techniques. The data were collected from patient medical records. ResultsThe success rate in hemorrhagic control was 96.2% and hemorrhagic control of the single case in which vascular ligation failed was obtained with total hysterectomy. Hypovolemic shock occurred in 19.2% of the patients and blood transfusion was required in 26.9%. No patient required intensive care unit treatment. Hypertensive syndrome was the most prevalent comorbidity (46.2%). The main etiology was uterine atony (65.4%). Uterine and/or pelvic adhesions and uterine lacerations associated with fetal extraction occurred in 19.3% and 15.4% of cases, respectively. ConclusionVascular ligations are efficient strategies for hemorrhagic control during cesarean sections and should be an integral part of the set of techniques that allow uterus preservation in the treatment of postpartum hemorrhage.
