Progress in endovenous treatment of thrombotic iliac vein compression syndrome
Thrombotic iliac vein compression syndrome(TIVCS)is caused by iliac vein compression,resulting in iliac vein return obstruction and blood stasis,followed by ipsilateral lower extremity deep venous thrombosis(LEDVT).Without effective treatment,it can lead to pulmonary embolism in the acute stage,seriously endangering the life and health,and may develop into lower extremity post thrombotic syndrome(PTS)in the later stage,which seriously affect the quality of life.At present,endovenous treatment is the main therapy,including inferior vena cava filter(IVCF)implantation,catheter directed thrombolysis(CDT),percutaneous mechanical thrombectomy(PMT),balloon angioplasty,and stent implantation.However,there is still controversy about the timing of iliac vein stenosis treatment,and there is no unified standard.Therefore,this article reviews the progress of endovenous treatment for TIVCS.
