AVF Day 3: Advances in Deep Venous and VTE Research
Femoropopliteal Disease and Outcome Measures
A case based talk questioned whether treating the femoropopliteal segment improves post thrombotic syndrome, noting mixed trial evidence. A companion talk argued clinician scales such as Villalta often miss symptoms patients find most important, favoring patient reported outcomes instead.
Basic Science and Risk Assessment
Laboratory work linked toll like receptor four signaling to urokinase expression and thrombus resolution in monocytes and macrophages. A systematic review found Caprini score thresholds associated with increased thromboembolism risk varied by specialty.
Registry and Treatment Comparisons
An international registry analysis found continental variation in venous thromboembolism presentation, anticoagulant choice, and mortality. A model based meta analysis suggested ultrasound assisted and catheter directed thrombolysis were associated with lower in hospital mortality than mechanical or surgical thrombectomy in high risk pulmonary embolism.
Emerging Tools and Special Populations
Additional talks covered catheter related thrombosis in neonatal intensive care patients, AI guided novice DVT compression ultrasound, covered stent outcomes for iliocaval occlusion, and a neurosurgical VTE algorithm.
