Background
Placenta previa is major obstetric surgical risk as it is associated with higher percentage of intraoperative and postpartum hemorrhage (PPH), increased requirement of blood transfusion and further surgical procedures. The current study aimed to evaluate uterine artery ligation prior to uterine incision as a procedure to minimize blood loss during cesarean section in patients with central placenta previa.
Methods
One hundred and four patients diagnosed with central placenta previa antenatally and planned to have elective caesarean section were recruited from the antenatal clinic at Minia Maternity University hospital. Patients were randomly allocated into either ligation group or control group.
Results
Both groups were similar regarding demographic features and preoperative risk factors for bleeding. The intraoperative blood loss was significantly lower in the ligation group as compared with the control group (569.3 ± 202.1 mL vs. 805.1 ± 224.5 mL respectively, p = 0.002). There was a significant increase in the requirement for blood transfusion in the control group as compared with the ligation group (786 ± 83 mL vs. 755 ± 56 mL respectively, p = 0.03) Three cases in the control group required further surgical interventions to control intraoperative bleeding, while no cases in the ligation required further surgical techniques and that was statistically significant (p = 0.001).
Conclusion
Uterine artery ligation prior to uterine incision may be a helpful procedure to minimize intraoperative and postpartum blood loss in cases with central placenta previa.
