Study finds drug eluting stents as effective as vascular brachytherapy in preventing restenosis
... "The efficacy of the SES in native coronary arteries
is proven -- but the safety and efficacy of drug eluting stents in the treatment of ISR is unclear. To help clarify these issues, we compared in-hospital and six month outcomes in patients with ISR treated either with SES or vascular brachytherapy (V...
