Results: Thirty-eight women were diagnosed of Cesaeran scar defect at TUS. The number of previous Caesarean sections in patients with uterine dehiscence and ectopic pregnancy in Cesarean scar is shown in Table 1. Eleven patients (29%) showed a uterine dehiscence. Seven cases were repaired by laparoscopy and 4 cases required hysterectomy. Five ectopic pregnancies (13%) were diagnosed at TUS. Two patients required hysterectomy, 2 were treated with local methotrexate guided by TUS and 1 was surgically sutured. Two patients (5%) had a complete uterine rupture. One of them diagnosed 6 months after Cesarean section and required hysterectomy. The other which was diagnosed during puerperium period was treated by surgical repair. Conclusions: TUS is useful for detecting Cesarean scar defects providing information for a treatment in case of complications.
