Background: Procedural complications of infrainguinal endovascular interventions are serious and costly. There are no validated models to predict complications of infrainguinal endovascular interventions.
Methods: Data from the multicenter Excellence in Peripheral Artery Disease (XLPAD) registry (NCT01904851) were analyzed to examine predictors of procedural complications in infrainguinal endovascular intervention. A predictive model was derived using penalized maximum likelihood estimation.
Results: Data from 2,353 interventions on 1,907 patients between January 2005 and October 2015 were analyzed. Procedural complication rate was 5.7%. Characteristics associated with a higher procedural complication rate included: Clinical (diabetes, chronic kidney disease), procedural (procedural duration, contrast volumes, and multiple lesion treatment), lesion characteristics (superficial femoral artery lesion, chronic total occlusions, heavy calcification, in-stent restenosis, and longer lesion length). Procedures using atherectomy and stents were associated with a lower complication rate (Figure 1.A). The final model performed well (area under the curve 74%) (Figure 1.B).
Conclusions: The proposed model based on simulation has optimal accuracy in predicting procedural complications of infrainguinal endovascular interventions. If validated, the model could aid in prediction and prevention of procedural complications.
