Abstract 【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 location, 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 between 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.
