Late Breaking Trials: New Devices and Data in Venous Care
Late Breaking Trials and Emerging Technology
This session previewed new devices and multicenter data spanning venous stenting, thrombectomy and pelvic venous disease.
Stenting and Restenosis
A new coring device for in-stent restenosis showed feasibility in early clinical use after preclinical testing in a pig model, while a large trial of a self-expanding venous stent reported 84 percent primary patency at 12 months in patients with IVC and iliofemoral obstruction.
DVT Thrombectomy Trials
- The BOLT study evaluated an aspiration system for iliofemoral DVT, with results expected this fall.
- A new mechanical thrombectomy system reported 85 percent clot burden clearance in a multicenter series.
- The Defiance randomized trial is comparing mechanical thrombectomy to anticoagulation alone for iliofemoral DVT.
Pelvic Disease and New Tools
The Embolize trial is a sham-controlled study of pelvic vein embolization for venous origin chronic pelvic pain, and a migration-resistant two-stent system was introduced for Nutcracker syndrome. Additional talks presented a calibrated color accuracy score for wound photography and photoacoustic imaging for locating lymphatic vessels.
