Asherman's Syndrome

Asherman's syndrome occurs when scar tissue forms inside the uterine cavity, most often after a dilation and curettage (D&C) procedure following a miscarriage or delivery. The adhesions can partially or completely obstruct the cavity, preventing embryo implantation and causing abnormal or absent periods.

Diagnosis is confirmed by hysteroscopy or a saline infusion sonogram. Treatment is hysteroscopic lysis (cutting) of adhesions, sometimes followed by estrogen therapy and placement of a balloon or IUD to prevent re-scarring while the endometrium heals.
