Two patients had iliac vein occlusion after treatment of artificial vascular arteriovenous fistula with Viabahn film mulching stent

With the aging of the population, diabetes mellitus, peripheral vascular diseases, and the increased dialysis age of hemodialysis patients, the depletion of upper limb blood vessels and superior vena cava resources is becoming more visible. Methods: The lower limb arteriovenous diameter is relatively large, and the first patency rate after artificial arterioplasty is high, with fewer thrombotic events. Results: As a result, arteriovenous grafts (AVG) are an important supplement to the hemodialysis pathway after the upper limb hemodialysis pathway has been depleted. The presence of iliac vein stenosis/occlusion following AVG of the lower limbs is uncommon and rarely reported in the literature. Conclusions: Recently, two cases of iliac vein occlusion and treated with Viabahn film mulching stent have achieved good clinical results, which are reported as follows
