目的探讨成人胃左静脉解剖及变异情况,分析胃左静脉及其属支与食管胃底静脉曲张破裂出血的相关性。方法收集2022年1月至2023年6月在佳木斯大学附属第一医院行上腹部CT增强检查的患者共300例,按照是否患门静脉高压分为病例组和对照组,其...目的探讨成人胃左静脉解剖及变异情况,分析胃左静脉及其属支与食管胃底静脉曲张破裂出血的相关性。方法收集2022年1月至2023年6月在佳木斯大学附属第一医院行上腹部CT增强检查的患者共300例,按照是否患门静脉高压分为病例组和对照组,其中病例组分为静脉曲张组和静脉破裂出血组,比较胃左静脉正常影像学解剖各分型构成情况及胃左静脉及属支管径大小,并评价各静脉预测食管胃底静脉曲张破裂出血的价值。结果300例患者中,胃左静脉正常影像学解剖主要包括静脉型、脾静脉型、交角型、肝内型;其中静脉破裂出血组中交角型7例,占比26.9%,比例高于对照组和静脉曲张组;300例患者中,男性197人,女性103人,胃左静脉管径大小男性为(4.53±1.93)mm,女性为(3.59±1.44)mm(P<0.05);静脉曲张组、静脉破裂出血组及对照组组间比较结果显示,胃左静脉、食管静脉、奇静脉、半奇静脉管径大小均表现为静脉破裂出血组>静脉曲张组>对照组(P<0.05);胃左静脉曲线下面积(Area Under the Curve,AUC)最大为0.827,截断值为6.83,灵敏度为65.4%,特异度为91.1%。结论胃左静脉管径大小可作为预测食管胃底静脉曲张破裂出血的重要指标,对预防及治疗出血起到一定预判作用。展开更多
