合并亚临床外周动脉疾病的血液透析及腹膜透析患者生存分析

Survival analysis of patients with subclinical peripheral artery disease undergoing peritoneal dialysis and hemodialysis

目的 探讨合并有亚临床外周动脉疾病的终末期肾病患者采用血液透析及腹膜透析的生存率.方法 纳入2010年1至6月在我院规律行肾脏替代治疗的患者进行筛选亚临床外周动脉疾病.记录其相关临床资料,随访至201 3年6月,评估患者预后情况.结果 经筛选,83例患者合并有亚临床外周动脉疾病（血液透析53例,腹膜透析30例）,Kaplan-Meier生存分析提示血液透析患者较腹膜透析患者生存率更好（P=0.045）.结论 在合并有亚临床外周动脉疾病的患者中,或许更适合选择血液透析作为肾脏替代治疗方式.

Objectives To explore the survival rate of the patients with subclinical peripheral artery disease （PAD） undergoing peritoneal dialysis （PD） and hemodialysis （HD）.Methods Patients regularly undergoing renal replacement therapy at our hospital from January to June,2010 were recruited into this study to screen subclinical peripheral artery disease.The clinic data were recorded.The patients were followed up to June,2013.The prognosis were assessed.Results After the screening,83 patients,53 undergoing hemodialysis and 30 peritoneal dialysis,had subclinical peripheral arterial disease.Kaplan-Meier survival analysis showed that the survival rate was higher in patients taking HD than in those taking PD （P=0.045）.Conclusions For patients with subclinical peripheral artery disease,HD may be a better choice as renal replacement therapy comparing with PD.
