Abstract:Objective To study the relationship between deep venous thrombosis(DVT) of lower extremity and Cockett′s syndrome(CS) in aged patients.
Methods Eighty nine patients with iliofemoral vein thrombosis, admitted during past 13 years, were divided into elder（>60 years）group and younger（≤60）group. Analysis of the pathogenesis of DVT in the 2 groups was made and the relationship of DVT and CS between the 2 groups was compared. There were 43 patients in elder group and 46 in younger group. All patients were treated by thrombectomy.
Results There were 25 (58.1%) patients with concomitant CS in elder group and 37 (80.4%) in younger group. There was a significant difference between the two groups (χ2=5.2274, P<0.05).
Conclusions CS is an important etiological factor for DVT. The incidence of DVT with CS in elder group is lower than that in younger group; but in the elderly, the incidence of DVT increases due to keeping to bed, trauma, fracture, tumor, high coagulability and other factors.
