Evaluation of Risk Factors for Stent Patency in Patients with Lower Limb Deep Vein Thrombosis Post Interventional Syndrome Using a Risk Column Chart Model
[Objective]To explore the risk factors for assessing stent patency in patients with deep vein thrombosis syndrome(PTS)after interventional procedures using a risk column chart model.[Methods]A total of 108 PTS patients who underwent iliac femoral vein balloon dilation combined with stent implantation in both hospitals from October 2019 to June 2022.Based on the stent patency during a 2-year follow-up,they were divided into a patency group(n=90)and a non patency group(n=18).Using logistic regression analysis to identify factors affecting postoperative stent patency,a column chart prediction model was established based on the results,and validated using calibration curves.[Results]There was a statistically significant difference in BMI(P＜0.05),antiplatelet therapy,stent number,thrombus blockage loca-tion,and elastic sock support treatment between the two groups(P＜0.05).Logistic multiple regression analysis showed that high BMI,lack of standardized antiplatelet therapy,number of stents ≥2,and non use of elastic stockings were risk factors affecting stent patency in PTS patients after intervention(P＜0.05).The column chart model results showed that PTS patients with high BMI,no standardized antiplatelet therapy,number of stents ≥2,and no use of elastic stockings had a higher risk of stent patency after intervention.The decision curve results showed that when the risk threshold was be-tween 0.2 and 0.8,the Nomogram curve was higher than the All and None curves,indicating that there was the maximum net benefit when the risk threshold was between 0.2 and 0.8.[Conclusion]PTS patients with high BMI,lack of standardized antiplatelet therapy,≥2 stents,and no use of elastic stockings have a higher risk of stent patency after intervention.
