RESUMEN
Objective · To investigate the performance of transvaginal ultrasound (TVS) on cesarean scar pregnancy (CSP), and evaluate the value of TVS combined with MRI in the diagnosis and treatment of CSP. Methods · A retrospective analysis was made in 42 patients with CSP in Shanghai General Hospital in recent 3 years. The TVS performance, MRI results, and clinical data of the patients were analyzed. Results · In all 42 cases, 36 were diagnosed as CPS. TVS missed one case, and misdiagnosed 5 cases, which diagnostic accuracy was 85.7%. Thirty-six cases were tested by MRI, therein 32 cases were diagnosed correctly, 3 cases missed, 1 case misdiagnosed, which diagnostic accuracy rate was 88.9%. Among the 36 CSP cases, 30 were simple sac type and 6 were mixedmass type. For the simple sac type, different treatment was chosen according to the muscle thickness of the lower uterine segment incision measured by TVS. When it was more than 3 mm, suction surgery was used. But when it was no more than 3 mm, MRI examination was further used, and the surgical resection or uterine artery embolism+MTX+suction surgery was chosen. Conclusion · Both TVS and MRI have a high diagnostic accuracy for CSP, and TVS combined with MRI can provide important reference for CSP treatment options.
