剖宫产切口瘢痕妊娠的超声表现及影响因素分析
Analysis of the ultrasonic findings and influencing factors of cesarean scar pregnancy
摘要
Abstract
Objective:To summarize the ultrasonic findings of cesarean scar pregnancy and to analyze the factors affecting the diagnostic accuracy.Methods:44 cases of patients who underwent uhrasonography and were confirmed with cesarean scar pregnancy by surgery and pathology in the hospital were studied.The clinical data and imaging data of all patients were collected to analyzed the ultrasonic characteristics and the influencing factors for cesarean scar pregnancy.Results:Among the 44 patients,there were 37 cases with cesarean scar pregnancy detected by transvaginal ultrasound and the coincidence rate was 84.09％.7 cases were misdiagnosed,accounting for 15.91％.The findings were divided into simplex gestational sac type and inhomogeneous mass type,including 27 cases of simplex gestational sac type of whom 20 cases were detected and the detection rate was 74.07％.17 cases of inhomogeneous massive type were detected.A total of 7 cases were misdiagnosed by transvaginal ultrasound.All were simplex gestational sac type,without specific symptoms.There were 4 cases misdiagnosed with inter-uterus early pregnancy,2 cases with inevitable abortion and 1 cases with cervical pregnancy.Ultrasound showed that the distance between gestational sacs and cesarean scar was longer than 2.5mm,indicating that the distance from the gestational sacs to cesarean incision scar may be the related factors influencing the diagnostic accuracy of ultrasound.Conclusions:To adopt transvaginal ultrasound in the diagnosis of cesarean scar pregnancy is easy to operate and noninvasive.The diagnostic accuracy is high and the distance from the gestational sacs to cesarean incision scar is the related factors influencing the diagnostic accuracy of ultrasound.关键词
