摘　　要：目的 探讨彩色多谱勒超声检测孕20~32周胎儿外侧裂形态变化及发育评估分级方法。方法 选取2020年1月至2023年12月内蒙古自治区人民医院超声检测的孕妇150例,其中80例胎儿获得右侧外侧裂分级,70例胎儿获得左侧外侧裂分级,分析不同孕周胎儿外侧裂分级情况,以及外侧裂深度与孕周的关系。结果 孕20~23周、24~27周和28~32周胎儿左、右侧外侧裂分级比较差异均有统计学意义(P <0.05),其中孕20~23周胎儿左、右侧外侧裂分级以1级为主,孕24~27周胎儿左、右侧外侧裂分级以3级以上为主,孕28~32周胎儿左、右侧外侧裂分级以4级以上为主。孕28~32周胎儿左、右侧外侧裂深度明显高于孕20~23周、孕24~27周(P <0.05),孕24~27周高于孕20~23周(P <0.05)。外侧裂深度与孕周呈正相关(rs=0.930,P <0.05)。结论 彩色多谱勒超声检测孕20~32周胎儿外侧裂发育评估分级在评估胎儿外侧裂发育成熟方面有一定应用价值,同时外侧裂深度与孕周有明显相关性。Objective To explore the morphological changes and development evaluation and grading method of fetal lateral fissures during the 20-32 weeks of gestation using ultrasound.Methods A total of 150 pregnant women who underwent ultrasound examinations at Inner Mongolia People's Hospital between January 2020 and December 2023 were selected.Among them,80 cases were classified based on the right lateral fissure,and 70 cases were classified based on the left lateral fissure.The classifications of lateral fissures at different gestational weeks and the relationship between the depth of lateral fissures and gestational weeks were analyzed.Results Statistically significant differences were observed in the grading of lateral fissures between the left and right sides at 20-23 weeks,24-27 weeks,and 28-32 weeks of gestation(P<0.05).Specifically,at 20-23 weeks of gestation,the grading of both left and right lateral fissures was mainly Grade 1;at 24-27 weeks,it was mainly Grade 3 or above;and at 28-32 weeks,it was mainly Grade 4 or above.In pregnant women with both left and right lateral fissures,the depth of the lateral fissures at 28-32 weeks of gestation was significantly greater than that at 20-23 weeks and 24-27 weeks(P<0.05).A positive correlation was found between the depth of lateral fissures and gestational age(rs=0.930,P<0.05).Conclusion Ultrasound grading of fetal lateral fissure development during the 20-32 weeks of gestation has certain application value in evaluating fetal lateral fissure development and maturity.Additionally,there is a clear correlation between the depth of lateral fissures and gestational age.
