Reviews Coronary Endovascular Brachytherapy

Currently, revascularization procedures !ike PTCA or coronary ste nting have been used in nuın ero u s cardiology centers. Although these methods are very successful in early term, their initial success are surpassed by the Iate term restenosis. Not maintaning early term success of these methods have led the researchers to study the prevention of the restenesis problem. Pharmacological interventions used to prevent have not reached very successful results. But, studies pertinent to th is issue are continuning. Therefore, it is pointed out that new elinical research and endovascu lar brachytherapy and the effects of ionizing radiation over restenosis area have been investigated. Different issues in the area of endovascular brachytherapy which is a relativetey new technique are stil! debateful or not clear enough. In this article, general principles of brachytherapy, the systems existing at present, and the l iteratuı·e related to this topic are reviewed.
