RESUMO
Objective To explore the curative effect on superselective uterine artery embolization for treatment of placenta inereta.Methods Pelvic arteriography was performed to confirm bleeding vessels.Then a 5 F Cobra catheter was inserted superselectively into uterine artery ipsilateral to bleeding,through which methotrexatum(MTX)and gelatin sponge were injected for embolization.After the procedure,bleeding,blood pressure,dischargement of placenta tissue,uterine recuperation,and plasma β-HCG were monitored.Results Bleeding vessels were confirmed in all of the 5 cases of placenta increta.Uterine artery embolization was successful at sole procedure.The operation time was 25.0 to 60.0 min.with the mean time (37.4±5.8)min.Vaginal bleeding stoped in 3.0 to 12.0 minutes after embolization and the mean time was(5.7±2.4)min.Blood pressure returned to normal after operation and vital signs were stable.Placenta tissue discharged on the 5th day to the 4th week after embolization and the mean time was 17 d.The uterus recuperated and blood β-HCG recovered simutaneously.The menstruation and ovulation during follow-up returned to normal.Conclusion Superseleetive uterine artery embolization for treatment of placenta increta has advantages such as short operation time,minimal invasion,definite curative effect and reservation of uterus,which is worthy in clinical application.
