摘要 传统的宫颈机能不全(cervical incompetence,CI)的概念是指妊娠中期无痛性的宫颈扩张,导致羊膜囊膨出,进而引起胎膜破裂造成晚期流产或早产。由于精确诊断困难,发生率不确切,各家报道也不一致,多数学者认在为0.05%~1%之间,约有10%~25%的妊娠晚期流产是由CI所导致。传统的诊断手段主要依据晚期流产和宫颈损伤的病史和当时的临床表现,如发生在妊娠中期的无痛性的胎囊膨出,国外还强调宫内的乙烯雌酚暴露史等,但是这种诊断是回顾性的,首次妊娠的CI患者不能得到及时诊断和治疗,同时依据病史而行的治疗手段如环扎术也相对缺乏客观依据。近10余年来超声检查广泛应用于宫颈形态的检测,
