摘要
对于有剖宫产史的子宫瘢痕处妊娠早孕病例,建议行经阴道彩色超声检查以了解胚胎的着床部位。三维超声、能量多普勒三维成像技术等的应用也提高了子宫瘢痕处妊娠的诊断率。而磁共振对于中晚孕的病例有较高的诊断价值,特别是对于怀疑有胎盘植入情况时。数字减影血管造影技术可以显示子宫动脉的分支,甚至子宫峡部血管分支出血的情况,对寻找病灶出血点,局部注射化疗药物、栓塞剂有切实的帮助。
While the a history of previous cesarean section, and an early first trimester transvaginal color Doppler ultrasound are advised to confirm the intrauterine location of the implantation site. Three dimensional ultrasound and three dimensional power Doppler ultrasound have improved the accuracy of diagnosis. Magnetic resonance imaging is used for late scar pregnancies, when the differential diagnosis has to be made between abnormal placentation such as accrete and normal placenta during the second or third trimester. Digital subtractive angiography can show the branches of uterine artery. In some cases, Digital subtractive angiography showed branches of uterine artery were bleeding, the site of the branches were equivalent to the lower segment of uterus.
