ABSTRACT
Objective To compare the clinical efficacy of extra vascular occlusion of low abdominal aorta and low abdominal aorta balloon occlusion in the treatment of placenta previa with placenta previa.Methods From January 2014 to July 2017,68 implantable placenta previa patients were divided into two groups,elective cesarean section of extra vascular occlusion of low abdominal aorta in 34 cases(group A)and cesarean section on the lower abdominal aorta balloon occlusion in 34 cases(group B),and observation of pregnant women was compared between surgery of two groups. Results Operation time,complications of vascular injury and thrombosis,fetal radiation exposure in group A were significantly lower than that of group B(P<0.05);two groups of patients with sensory dysfunction incidence,cesarean operation time,intraoperative blood loss,blood transfusion rate,the uterus resection rate,hospitalization time had no statistically significant difference postoperatively(P > 0.05). Conclusion Two kinds of operation can safely and effectively reduce the bleeding during the treatment of placenta previa. While group A surgery operation time is short,without intraoperative and postoperative bleeding of the puncture site,without pelvic and lower extremity arterial thrombosis,without X-ray exposure,more safety of the womb and can be popularized in clinic.
