Intracoronary beta-irradiation with a rhenium-188-filled balloon catheter: a randomized trial in patients with de novo and restenotic lesions.
BACKGROUND Restenosis requiring reintervention is the main limitation of coronary angioplasty. Intracoronary irradiation reduces neointimal proliferation. We studied the efficacy of a self-centering liquid rhenium-188-filled balloon catheter for coronary beta-brachytherapy. METHODS AND RESULTS After successful coronary angioplasty with or without stenting, 225 patients (71% de novo lesions) w...
متن کاملPreserved endothelium-dependent vasodilation in coronary segments previously treated with balloon angioplasty and intracoronary irradiation.
BACKGROUND Abnormal endothelium-dependent coronary vasomotion has been reported after balloon angioplasty (BA), as well as after intracoronary radiation. However, the long-term effect on coronary vasomotion is not known. The aim of this study was to evaluate the long-term vasomotion of coronary segments treated with BA and brachytherapy. METHODS AND RESULTS Patients with single de novo lesion...
متن کاملOptimization of Natural Rhenium Irradiation Time to Produce Compositional Radiopharmaceutical
Introduction: Previously, 186Re and 188Re radioisotopes have been produced through appropriate activities, and each of them has been used for therapeutic applications. The 186Re and 188Re have unique properties, which make them proper for the treatment of tumors in different sizes. The long-range 188Re, is suitabl...
متن کاملIntravascular Ultrasound Balloon Catheter
Background Coronary stenting in conjunction with coronary angioplasty is a valuable tool for treatment of severe coronary dissection and is effective in reducing the frequency of restenoses. Evidence is increasing that the lumen gain within the stent is negatively correlated with the rate of subacute closures and restenoses. Since the assessment of radiolucent coronary stents and complex lumen ...

a more clinically relevant time frame. Methods and Results. We used a perforated balloon (Wolinsky) catheter to inject retroviral vectorcontaining virions into rabbit aortas in vivo. The virions were injected within 1 minute. Aortas were removed 5-14 days after injection and analyzed for evidence of gene transfer. In initial studies, nine rabbits were injected with a vector expressing the 3-gal...
