RESUMO
Objective To evaluate the clinical and technical effects of self-expanding VENA stent in the treatment of iliofemoral vein obstruction.Methods The clinical data of 58 patients(61 limbs) with symptomatic iliofemoral vein obstructive disease treated by VENA stent from February 2017 to June 2018 were collected and analyzed.The patency of the vein was assessed by the results of intraoperative angiography and postoperative symptoms relief changes in leg circumference.Follow up included relief of symptoms,Doppler ultrasound.Results A total of 63 VENA stents (43 in the left limb and 20 in the right limb) were implanted,sizes ranging from 12 mm to 16 mm,surgical technique success rate was 100％.The median follow-up time was 8.6 months.The primary patency rate of one month,three months,six months and 12 months was 96％,94％,92％ and 92％,respectively.Leg circumference fall down from(48 ±0.4) cm to (37 ± 0.3) cm (P ＜ 0.05).Conclusion Self-expanding nitinol stent implantation is a safe and effective treatment method for symptomatic iliofemoral vein obstruction disease.
