Radiofrequency wire-assisted recanalization of chronic venous stent occlusions.
Journal Article J Vasc Surg Cases Innov Tech · February 2026 Venous in-stent reocclusion can result in recurrent obstructive symptoms. Occlusions that are recalcitrant to traditional crossing techniques are inaccessible to effective therapies. However, radiofrequency-assisted recanalization techniques can mitigate t ...
