ESAL: A Tool for the Explanatory Prediction of Loss of Patency Within 1 Year After Iliac Vein Stent Placement

We present a novel, intuitive model for assessing patency loss risk after IVSP. The ESAL classification provides clinicians with a practical tool to identify high-risk patients. Future research should focus on larger, more representative cohorts to validate and refine the model.Clinical ImpactHow will this change clinical practice?The risk of iliac vein stent patency loss within one year post-placement can be predicted in advance.What does it mean for the clinicians?The newly introduced Etiology-Stenosis-Age-Length (ESAL) Classification offers clinicians a practical and user-friendly tool for identifying high-risk patients who may experience patency loss after iliac vein stent placement.What is the innovation behind the study?Researchers have successfully developed a predictive model for assessing the risk of iliac vein stent patency loss within one year post-placement.
