Abstract:Objective:To explore the correlation between Cockett syndrome( stenosis of the left common iliac vein)and the relapse of acute deep vein thrombosis of the left lower extremity after thrombectomy.
Methods :The causes of relapse in 78 cases of acute deep vein thrombosis of the left lower extremity after thrombectomy performed in the past 11years were reviewed.
Results:The relapse rate was 47.6%(10/21) in the group with Cockett syndrome when thrombectomy was done but the stenosis of the left common iliac vein was not treated. The relapse rate was 14.8%(4/27) in the group with Cockett syndrome when thrombectomy and the stenosis of the left common iliac vein were treated. The relapse rate was 13.3%(4/30) in the group without Cockett syndrome.
Conclusions:Cockett syndrome is an important cause for the relapse of acute deep vein thrombosis of the left lower extremity after thrombectomy. The relapse rate was markedly decreased when thrombectomy combined with aggressive treatment of the stenosis of the left common iliac vein were performed.
