剖宫产术后子宫切口瘢痕处妊娠(以下简称瘢痕妊娠),指胚胎附着于剖宫产术后子宫切口瘢痕的微小缝隙上,是一种特殊类型的异位妊娠,发生率很低为1:1 800～2 216[1,2]。但近年来随着剖宫产率的上升有所增加,其切口妊娠也有上升趋势[3,4],并伴有严重的并发症。子宫下段切口处早期胚胎着床是剖宫产的远期并发症之一,临床若在诊断不明的情况下,以宫内早期妊娠行人工流产或药物流产时,则有可能发生意外的大出血[5],部分年轻患者有遭遇子宫全切的报道[6]。因此,应早期超声检查,明确其诊断,尽早终止妊娠,减少出血量,以保留患者的生育能力。本文旨在分析剖宫产术后子宫切口部妊娠的声像图特点及分型,探讨其诊断价值。
After cesarean section uterine incision scar pregnancy (hereinafter referred to as scar pregnancy), refers to the embryo attached to the uterine incision cesarean scar scar small gap, is a special type of ectopic pregnancy, the incidence is very low as 1 : 1 800 ~ 2 216 [1,2]. However, with the increase of cesarean section rate increased in recent years, the incisional pregnancy also has an upward trend [3,4], accompanied by serious complications. Lower uterine incision early embryo implantation is one of the long-term complications of cesarean section, clinically in the case of unknown diagnosis, intrauterine early pregnancy abortion or medical abortion, then there may be unexpected bleeding [ 5], some young patients suffered hysterectomy reported [6]. Therefore, early ultrasound examination should be made clear its diagnosis, termination of pregnancy as soon as possible to reduce the amount of bleeding in order to retain the patient’s fertility. The purpose of this paper is to analyze the characteristics and classification of gestational uterine incision pregnancy after cesarean section, and to explore its diagnostic value.
