As a structured, multinational retrospective registry the AVATAR Registry addresses the following scientific aspects through systematic data collection, centralized quality control, and robust statistical analysis in patients that were treated with the AngioVac Aspiration System: 1. Quantify Real-World Safety: Composite adverse event rates across diverse populations and indications 2. Assess Effectiveness: Technical and clinical success rates stratified by indication 3. Identify Predictors: Clinical, procedural, and anatomical factors predicting success versus complications 4. Generate Publishable Cohorts: Sufficient statistical power (approx. 1000 patients across 8 indication cohorts) for: * Indication-specific outcomes * Multivariable prediction models * Time-to-event analyses (30-day and 12-month mortality) 5. Establish Best Practices: Evidence-based recommendations for patient selection, procedural technique, and follow-up
