Abstract: This paper mainly analyses the effect of DSA-guided bilateral uterine artery embolization in patients with penetrating risky placenta previa and its effect on maternal and fetal outcomes. A total of 45 patients with penetrating sinus placenta previa were selected from December 2017 to July 1919. They were divided into non-uterine embolization group (n=20 cases) and uterine artery embolization group according to different treatment methods (n=25 cases). The non-uterine embolization group was given routine intervention. The uterine artery embolization group underwent DSA-guided bilateral uterine artery embolization. The effect of the patients was evaluated 7 days after surgery. The surgical indexes, maternal and infant outcomes and complication rates were compared between the two groups. The results show that:the blood loss, red blood cell transfusion, cryopreserved blood transfusion, hospitalization time of the observation group were less (short) than the control group (P<0.05). The Agmin score of the newborn group was higher than that of the control group (P<0.05). The incidence of neonatal pneumonia, neonatal respiratory distress syndrome, neonatal asphyxia and neonatal hyperbilirubinemia were lower than those in the control group (P<0.05). There was no statistically significant rate of puerperal infection in the two groups (P<0.05); the incidence of hysterectomy, postpartum hemorrhage, hemorrhagic shock and DIC in the observation group was lower than that in the control group (P<0.05). DSA-guided bilateral uterine artery embolization for penetrating sinister placenta previa has less surgical trauma, which can improve the outcome of maternal and child, and the postoperative complication rate is low, which is worthy of popularization and application.

Key words: DSA guidance, bilateral uterine artery embolization, penetrating sinister placenta previa, maternal and child outcomes
