目的:探讨肝硬化食管静脉曲张破裂出血(esophageal varices bleeding,EVB)的危险因素.方法:回顾性分析178例肝硬化食管静脉曲张患者的临床资料,其中出血组118例,未出血组60例;分别统计2组24个指标,通过t检验、χ2检验和多因素非条件Logi...目的:探讨肝硬化食管静脉曲张破裂出血(esophageal varices bleeding,EVB)的危险因素.方法:回顾性分析178例肝硬化食管静脉曲张患者的临床资料,其中出血组118例,未出血组60例;分别统计2组24个指标,通过t检验、χ2检验和多因素非条件Logistic回归分析得出肝硬化EVB的危险因素.结果:出血组与未出血组之间红细胞计数、血红蛋白、血清白蛋白、凝血酶原活动度、肝功能Child B级、肝功能Child C级、既往E V B史、门静脉内径、脾静脉内径、脾脏厚度、红色征差异有统计学意义.多因素非条件Logistic回归分析结果提示血红蛋白(OR=0.204,P=0.001)、血清白蛋白(O R=0.126,P=0.000)与E V B风险呈负相关,既往E V B史(OR=3.622,P=0.01)、门静脉内径(OR=2.619,P=0.032)、红色征(OR=4.647,P=0.001)与EVB风险呈正相关.结论:贫血、低蛋白血症、既往EVB史、门静脉内径增宽、红色征阳性是EVB的独立危险因素.展开更多
