目的:探讨前置胎盘发生的病因及治疗。方法:回顾性分析132例单胎前置胎盘发生的病因及治疗方法。结果:前置胎盘主要的发病原因是流产史、引产史、前次剖宫产史、多产史、盆腔炎史、辅助生育技术史、高龄。剖宫产率77.3%,产后出血率61.4%,出血原因有子宫收缩乏力、胎盘附着面出血、胎盘粘连及植入。结论:减少人流及引产,严格掌握剖宫产指征,降低剖宫产率,实行计划生育,注意生殖卫生是防止发生前置胎盘的重要措施;前置胎盘产后出血可采用加强宫缩、宫腔填纱、子宫动脉或髂内动脉结扎、子宫胎盘创面缝合、胎盘植入部位子宫肌层切除术、子宫切除,以及子宫动脉栓塞、髂动脉球囊导管置入术、改良B-Lynch外科缝合术、宫内球囊压迫术等新的治疗方法。
