Objective To compare the efficacy and complications of different types of stents in the treatment of iliac vein stenosis and occluded diseases by observing the mid-term outcomes after stent implantation. Methods The clinical data of 83 patients with unilateral iliac vein stenosis or occlusion treated with stenting in our department from June 2018 to June 2020 were collected and analyzed retrospectively. All of the patients were followed up for 3-12 months (mid-term). The efficacy and incidence of complications were compared between the patients undergoing woven stent (woven stent group, n=34) and laser engraving stent (laser stent group, n=49). The clinical outcomes were evaluated for the mid-term clinical efficacy in terms of swelling rate, primary patency rate of the target vessel, venous clinical severity score (VCSS) and complication rate. The obtained data were analyzed by SPSS statistics 13.0, and the intergroup comparison was conducted with student′s t test or Chi-square test based on different data types. Results The circumferences of the thigh and the calf of the affected side were obviously decreased at follow-up than those before treatment in both groups (P<0.05). So was the VCSS score before and after treatment (P<0.05), but there was no statistical difference in the score between the two groups (P>0.05). No differences were seen in the swelling rate and primary patency rate of the target vessel between the two groups (P>0.05). The incidence of contralateral iliac vein thrombosis, stent displacement and stent thrombosis were higher in the woven stent group than the laser engraving stent group [20.59% (7/34) vs 4.08% (2/49)], the difference was statistically significant (P<0.05). Conclusion Stent implantation is safe and effective in the treatment of iliac vein stenosis and occlusion. Woven stents show similar efficacy as laser engraving stents and obtain more accurate positioning and lower complication incidences.
