چکیده
Vascular stenosis mainly on the basis of arteriosclerotic disease represents one of the major problems in cardiovascular disease. Vascular stenosis contributes significantly to the clinical consequences of arteriosclerotic disease being the leading cause of death in western countries. The etiology of vascular disease is very complex and many factors have been implicated such as abnormalities of fat lipometabolism (elevated LDL-cholesterin), elevated blood pressure, and nicotine. The prognosis of stenotic vascular disease varies mainly with the location and extent of the disease, and is also dependent on accompanying diseases like diabetes and hypertension.

Dosimetry of 188Re and 186Re sources based on Monte Carlo calculations for endovascular brachytherapy after balloon angioplasty
Background: Recent pre-clinical and clinical studies indicate that irradiation in the dose range of 15 to 30 Gy can reduce rate of restenosis in patients who have undergone an angioplasty. The use of filled balloon with radioactive solution was proposed as one of the possible intravascular irradiation techniques. Materials and Methods: The Monte Carlo N-particle Transport Code (MCNP4b) was used...

Late acute thrombotic occlusion after endovascular brachytherapy and stenting of femoropopliteal arteries.
OBJECTIVES The aim of this article is to underline the importance of this complication after endovascular brachytherapy (EVBT) and intravascular stenting of the femoropopliteal arteries occurring in a running randomized trial. BACKGROUND Endovascular brachytherapy has been proposed as a promising treatment modality to reduce restenosis after angioplasty. However, the phenomenon of late acute ...

Brachytherapy: True or False? To the Editor: We read with great interest the article about the mechanism of action of endovascular brachytherapy after balloon angioplasty published by Sabaté et al.1 Intravascular ultrasound (IVUS) imaging provides an extremely effective means of examining vessel changes after interventions and it seems to be critical in the objective evaluation of radiation the...
متن کاملEndovascular brachytherapy for prophylaxis of restenosis after femoropopliteal angioplasty : results of a prospective randomized study.
BACKGROUND Inasmuch as endovascular brachytherapy (BT) has gained recent interest because of its inhibitory effect on mechanisms leading to restenosis after percutaneous transluminal angioplasty (PTA), we performed this randomized study to determine its efficacy for prophylaxis of restenosis after femoropopliteal PTA. METHODS AND RESULTS One hundred thirteen patients (63 men, 50 women; mean a...
