ABSTRACT
Objective To assess the risk factors of postphlebitic syndrome(PS)after deep vein thrombosis of the lower extremities. Method In this study,102 DVT patients managed by conservative therapy were recruited.Data including age,sex,etiopathogenesis,anticoagulation,pathogenesis, elasticstocking therapy,degree of lower extremity exercise,INR,WBC,PT%and FIB were analyzed by single factor analysis and COX analysis. Result PS developed in 67.60%cases,single factor analysis shows:sex(P=0.025),anticoagulation(P=0.000),elastic-stocking therapy(P=0.000),degree of lower extremity exercises(P=0.000),INR(P=0.033),WBC(P=0.012),PT%(P=0.000),FIB(P=0.002)are related to the occurrence of PS.COX regression shows that anticoagulation(P=0.011),the degree of lower extremity exercise(P=0.019),elastic-stocking therapy(P=0.000)are related to PS.Age (P=0.299),etiopathogenisis(P=0.838)and pathogenesis(P=0.2 17)are not statistically PS related.Conclusion DVT is a multi-factors related disease.Multivariant analysis revealed that elastic-stocking (P=0.000),anticoagulation(P=0.011)and the degree of lower extremity exercises(P=0.019)are related to the development of PS.
