Hallo
Your daughter has 3 congenital fistula out of which 2 are blocked and one more is still to be blocked.This procedure of blocking the fistula is called as coil embolization of a fistula in which a coil is place at a site of fistula so that it blocks the abnormal opening through which blood flows through the abnormal
artery .Whatever the doctor has done is correct and go ahead for the blockage of the third one as suggested by your dr.This will cure the defect permanently
