International Session: Vein Biology, Stents and Sclerotherapy
Venous Wall Biomechanics and Stent Thrombosis Biology
Ramon Turinsky’s ex vivo study found physiological hydrostatic pressure alone did not induce tensile creep in intact veins, while Adam Gwadz found reduced pre-stent platelet reactivity predicted which patients later developed in-stent stenosis.
Open Versus Closed Cell Dedicated Venous Stents
Rachel Morris compared 209 patients treated with open or closed cell dedicated venous stents for chronic iliofemoral obstruction, finding no significant difference in patency or symptom improvement at one year, though inflow disease was the only factor significantly associated with patency loss.
Serious Complications of Sclerotherapy
A case series described three rare, serious sclerotherapy complications: Takotsubo syndrome with transient chest pain, a paradoxical air embolism through a patent foramen ovale causing stroke symptoms that fully resolved, and a massive pulmonary embolism after a hybrid ablation procedure.
Combined Laser Ablation and Sclerotherapy
A 576 patient study of single session laser ablation with sclerotherapy found 99.6 percent anatomical success at 24 months, significant severity score improvement, and high satisfaction, supporting one stage treatment over staged procedures for superficial venous incompetence.
