Villavicencio Symposium: Global Venous Disease Research

Iliac Vein Stenting Outcomes and Trial Design

A single center review found venous quality of life and Villalta scores improved after iliac vein stenting and remained better through three years, and a new UK trial will compare deep venous stenting against medical therapy alone in post-thrombotic and non-thrombotic patients.

Artificial Intelligence for Assessing CVI

A neural network trained on MRI venogram images distinguished normal from diseased limbs with 97 percent accuracy, and texture and area analysis of the superficial and deep compartments found measurable differences consistent with inflammation and fibrosis in venous insufficiency.

Comparative Ablation and Valve Technologies

A randomized trial found no significant difference between mechanochemical ablation and cyanoacrylate for pain or quality of life, though ablation was faster, while thirty month data on an implantable venous valve showed sustained improvement in reflux and severity score without complications.

VTE Risk Scoring in COVID-19

Among hospitalized COVID-19 patients, the Caprini and IMPROVE scores predicted symptomatic thromboembolism more accurately than the Padua score, and high risk thresholds needed revision since most patients screened high risk under Caprini or Padua criteria regardless of outcome.
