Ultrasound Evaluation of Uterine Healing After Vaginal Repair of Cesarean Scar Defect (CSD) (CSD)

Cesarean scar defect is one of the complications after cesarean section (CSD). CSD may be further caused many long term complications, such as abnormal uterine bleeding, infertility, uterine scar pregnancy and uterine rupture. Vaginal repair due to CSDs is a minimally invasive and effective method that maintains fertility. The main concern linked to surgery is the quality of healing of the myometrial incision. However, no diagnostic method has yet been widely accepted to assess the healing process. Thus, the authors investigated uterine healing after vaginal repair with two-dimensional (2D) power Doppler ultrasound (PDU) in this study.

Detailed Description

The inclusion criteria were CSD patients who had one or more cesarean deliveries, patients who had intermenstrual spotting after the cesarean section or those in which the thickness of the residual myometrium (TRM) was less than 3.0 mm at the preoperative stage.

Patients who had a history of endocrine disorders, coagulation disorders, use of intrauterine devices, sub-mucous myoma, endometrial diseases, endometrial cysts, uterine fibroids, and adenomyosis after cesarean section were excluded from this study.

After vaginal repair, all patients were followed by traditional 2D US scanning and Doppler velocimetry on Days: 0, 2, 30, 60 and 90. Authors evaluated: scar diameter and Doppler velocimetry and resistance index (RI) of the uterine arteries, at their ascending branch.
