RESUMEN
OBJECTIVE: It was to analyze two failed arterial embolization cases in the treatment for pseudoaneurysm followed by D&C. METHODS: Two failure cases out of eight cases were gained in the transarterial embolization treatment for eight years.(1. 1. 1992 - 12. 31. 1999) To search for the factors of failure, we went through obstetrical history and biopsy. RESULTS: Eight cases of transarterial embolization were performed to the treatment for pseudoaneurysm appeared after undergoing D&C. Six cases were successfully treated without complications. However, laparotomy was done due to the continuous bleeding in the other two cases. According to tissue biopsy, they showed the cervical pregnancy in one case and placenta accreta in the other. CONCLUSION: Transarterial embolization is proved to be more preferable to operate in the treatment of pseudoaneurysm than laparotomy, and transarterial embolization therapy failure rate is higher in case of existing remnant villi than not.
