摘要 目的:研究辅助生殖技术(ART)与自然妊娠(NC)孕早期流产绒毛组织染色体异常情况。方法:按照辅助生殖助孕和自然受孕将205例患者分为ART组(60例)和NC组(145例);将每组患者按年龄分为<35岁及≥35岁,按既往连续发生自然流产的次数分为<2次及≥2次。取两组流产绒毛组织进行NGS染色体分析,比较各组染色体异常情况。结果:ART组与NC组染色体异常率分别为56. 67%(34/60)、52. 41%(76/145),差异无统计学意义(P>0. 05)。ART组与NC组染色体数目异常和结构异常进行比较,差异均无统计学意义(P>0. 05)。<35岁及≥35岁染色体异常率,ART组为45. 71%、72. 00%; NC组为45. 63%、69. 05%,差异均有统计学意义(P<0. 05)。两组流产次数<2次与≥2次的患者染色体异常率比较,差异均无统计学意义(P>0. 05)。结论:与NC相比,ART不增加自然流产胚胎染色体异常的发生率,无论ART或NC绒毛染色体异常率与流产孕妇的年龄存在着一定的关系。年龄越大染色体异常率越高。但与患者流产次数无关。利用NGS技术检测流产绒毛染色体异常,可为遗传咨询和再生育风险评估提供指导。
