Calcified foci after miscarriage may not be helped by medication, and if the foci are large, surgery may be needed. Calcified foci found on ultrasound after miscarriage may be caused by a small amount of residue in the uterine cavity after miscarriage, which is a benign lesion. If there is only a small amount of calcified foci in the uterine cavity, this condition basically will not affect a woman’s fertility, and basically will not cause any adverse effects, so there is no need for treatment in this case. If an ultrasound examination reveals that the foci of calcification are relatively large, this may affect future pregnancies. This is because if the fertilized ovum is deposited at the location of the calcified foci, it may be prone to biochemical pregnancy. If this is the case and medication does not help much, electrosurgery can be done under hysteroscopy.
