The clinical value of transvaginal ultrasound in clinical surgical treatment of cesarean scar pregnancy(CSP) was evaluated. The clinical data of 104 patients with CSP admitted at Tongji Hospital from 2013 to 2016 were collected and analyzed retrospectively, including the patients' age, gestational age, the size of gestational sac or uneven mass, the uterine scar thickness, β human chorionic gonadotropin(h CG) levels and so on. Of these 104 cases, 30 cases were subjected to laparotomy, 29 cases to laparoscopy, 27 cases to hysteroscopy, 16 cases to ultrasound-guided uterine curettage, and 2 cases to conservative treatment. The transvaginal ultrasound showed that uterine scar thickness and gestational sac or uneven mass size had significant difference(P〈0.05) among different surgical methods by comparatively analyzing the patients' data. It was suggested that transvaginal ultrasound may provide the valuable reference for choosing clinical surgical procedures for CSP. 展开更多
