Uterine cryoblation can help with abnormal uterine bleeding and menorrhagia, which is unusually long or heavy menstrual periods, according to Johns Hopkins Medicine. Abnormal uterine bleeding is typically bleeding between periods. It may be caused by fibroid tumors, polyps, or cancer of the uterus or endometrium.
The endometrium is the lining of the uterus that sheds once a month during the menstrual cycle, reports Johns Hopkins Medicine. Uterine cryoblation, as well as other ablation techniques, destroys the endometrium to stop abnormal, prolonged or excessive bleeding. Since the procedure prevents a woman from getting pregnant, most women undergo cryoblation after having children.
Cryoblation involves using a probe that emits extremely cold temperatures to freeze the endometrium, explains Johns Hopkins Medicine. The probe is placed in the uterus via the cervix, and doctors use ultrasound to place the probe in the areas requiring treatment. The procedure sometimes causes cramping.
Some patients are not candidates for uterine cryoblation, states Johns Hopkins Medicine. They may include women who have undergone surgery for fibroid tumors or a C-section, as well as those with vaginal or cervical infections. Women who have recently been pregnant, use an IUD, or have a weak uterine wall or abnormally shaped uterus also may not be candidates for the procedure.
