胚胎移植时导管尖端与宫腔中线夹角对临床妊娠率的影响OA
Impact of angle between catheter tip and uterine cavity midline during embryo transfer on clinical pregnancy rate
目的:探讨胚胎移植时导管尖端与宫腔中线夹角对临床妊娠率的影响.方法:回顾性分析190例行超声引导下胚胎移植患者的临床及超声资料,根据导管尖端与宫腔中线夹角分为2组:≤12°组95例,>12°组95例.比较2组胚胎移植术中导管尖端接触内膜底部、导管尖端出现血迹情况、临床妊娠率及着床率等妊娠结局.结果:≤12°组导管尖端接触内膜底部及导管尖端出现血迹的情况均低于>12°组,差异均有统计学意义(均P<0.05).≤12°组的临床妊娠率、着床率及多胎妊娠率均高于>12°组,差异均有统计学意义(均P<0.05).结论:胚胎移植时导管尖端与宫腔中线夹角≤12°可获得更高的临床妊娠率.
Objective:To investigate the impact of the angle(α)between the catheter tip and the uterine cavity midline during embryo transfer on the clinical pregnancy rate.Methods:Clinical and ultrasound data of 190 patients undergoing ultrasound-guided embryo transfer were retrospectively analyzed.Patients were divided into two groups based on angle α,the group of α≤12°(95 cases)and the group of α>12°(95 cases).The outcomes were compared including catheter tip contacting endometrial fundus,catheter tip blood staining,clinical pregnancy rate,and implantation rate.Results:The group of α≤12° showed significantly lower incidences of catheter tip contacting endometrial fundus and catheter tip blood staining,and higher rates of clinical pregnancy,implantation and multiple pregnancy compared to the group of α>12°(all P<0.05).Conclusion:Maintaining an angle of α≤12° between the catheter tip and the uterine cavity midline during embryo transfer is associated with significantly improved the clinical pregnancy rates.
