Value of deep vein ascending venography in the diagnosis of iliac vein compression syndrome

Abstract

Objective To evaluate ascending venography in the diagnosis of iliac vein compression syndrome.Methods From April 2011 to April 2013,we have had 556 patients with varicose veins suspected of Cockett syndrome.The degree of varicose veins by the International Union of Venous Clinical Classification (CEAP classification) was as following[1]:shallow varicose veins of lower limb (C2) in 190;varicose veins with limb swelling (C3) in 149 cases ; with body skin changes,such as pigmentation,eczema or lipid hard skin disease (C4) in 130; with healed ulcers (C5) in 17; with active ulcer(C6) in 70.Deep vein anterograde contrast and femoral venous cannula angiography were performed on 760 times.Results Iliac vein compression syndrome (Cockett) was detected by ascending venography in 154 patients,the diagnosis was established by following femoral venous cannula angiography.In the other 48 patients in whom Cockett syndrome was suspected by ascending venography,final diagnosis was reached by femoral venous cannula angiography.Altogether there were 202 iliac vein compression syndrome cases,with a positive rate 38.19％ (202/529).The narrowness was larger than 50％ in 173 cases.In 145 cases there were visible collateral vessels.Conclusions Deep vein ascending angiography is a useful screening method in the diagnosis and treatment of Cockett syndrome.
