Blood flow characteristics of uterine scar diverticulum probed by transvaginal three-dimensional ultrasound

Abstract

Objective To analyze the blood flow parameters of the peripheral muscle of uterine scar diverticulum by transvaginal 3D energy Doppler ultrasonography and to explore the formation characteristics and clinical value of the small peripheral muscle vessels of diverticulum. Methods The patients with a history of cesarean section treated at our hospital from March, 2014 to May, 2017 were collected. The patients diagnosed with uterine scar diverticulum or completely recovered uterine scar by ultrasound were detected by transvaginal 3D energy Doppler untrasonography. The values of VI, FI, and VFI were analyzed with Vocal software. Results The proportion of posterior position was 74.12% in the case group and was 35.65% in the control group (P = 0.005). The case group took (1.55 ± 0.64) times cesarean section and the control group (1.09 ±0.56) (P= 0.004). In the early period of menstruation, the values of VI, FI, and VFI were (5.719±3.012), (35.266±5.818), and (2.104±1.370) in the case group and were (1.359±0.893), (28.809±3.409), and (0.415±0.304) in the control group. Conclusions In the early stage of menstruation, the blood supply of the uterine scar diverticulum is characterized by rich blood flow surrounding the cicatrial diverticulum, low velocity, and angiogenesis. The complete blood supply of cicatrial scar is characterized by the lack of blood flow around the scar. Posterior uterine uterus is more easily prone to scar diverticulum; and the more frequent caesarean section is, the greater the chance of developing scar diverticulum is.
