Key points analysis of stent implantation for iliac vein occlusion

Abstract

The incidence of iliac vein occlusion is high in clinics. Most of them are latent disease. Non-thrombotic iliac vein occlusion is an important cause of chronic venous diseases in lower limbs. Post thrombotic syndrome and iliac vein compression syndrome are two main forms non-thrombotic iliac vein occlusion. Stent implantation is the first-line treatment method for iliac vein occlusion. Reasonable stent diameter selection and accurate positioning are two key technical points to ensure high patency rate of iliac vein stent. Intravascular ultrasound plays an important role in diagnosing iliac vein occlusion and stenting. After iliac vein stent implantation, regular ultrasonic follow-up is required, and optimal postoperative drug therapy is still controversial. The development and application of new specialized iliac vein stent is expected to further improve the clinical effect of iliac vein stent implantation. Key words: Iliac vein; Stent; Implantation
