R ecent pre-clinical and clinical studies indicate that irradiation within the dose range of 15 to 30 Gy can reduce the rate of restenosis in patients who have undergone an angioplasty (Nath 1999, King 1998). Several delivery systems of intravascular brachytherapy have been developed to deliver doses within this rang with minimal normal tissue toxicity. One of the possible intravascular irradia...
OBJECTIVES We studied the efficacy of intracoronary brachytherapy (ICB) after successful coronary stenting in diabetic patients with de novo lesions. BACKGROUND Intracoronary brachytherapy has proven effective in preventing recurrences in patients with in-stent restenosis. However, the role of ICB for the treatment of de novo coronary stenoses remains controversial. METHODS Ninety-two patie...
AIMS To assess the feasibility, safety and effectiveness of intravascular brachytherapy (VBT) in routine clinical practice. METHODS AND RESULTS Between April 1999 and September 2000, 1098 consecutive patients treated in 46 European centres by intraluminal irradiation using a Sr/Y(90)source train (BetaCath, Novoste, GA) were included in a registry, and follow-up data were obtained for 98.8% of...
This study identifies basic dosimetric differences between two designs for intravascular brachytherapy (IVBT) in current clinical practice and ongoing trials and their clinical implications within beta emitting systems using P-32 as an example. The two designs are (i) the wire-type source, where the radioactive source material is confined to a wirelike structure within the vessel lumen, and (ii...
Background: Intravascular imaging is a tool to detect coronary artery atherosclerosis which plays the major role in vessel stenosis degree determination and plaque pathology as a supplement of invasive angiography. This study aimed at comparing Intravascular imaging with invasive angiography. Materials and Methods: For retrieving second type studies, PubMed, Cochrane Library and Centre for R...
Vascular Brachytherapy using beta and gamma radiation is the standard care for patients with in-stent restenosis (ISR). The reported incidence of ISR varies from 7-37% of patients who undergo bare metal stent implantation and is dependent on patient characteristics, lesion morphology, and procedural technique. The recurrence rate after treatment for ISR varies among reported series but remains ...
OBJECTIVE To compare the clinical efficacy of concurrent chemoradiotherapy, neoadjuvant chemotherapy, and intracavity brachytherapy in comprehensive treatment for young patients with stage Ib2 cervical cancer. METHODS One hundred and twelve young patients with stage Ib2 cervical cancer were enrolled retrospectively in our hospital from January 2003 to June 2005. They were categorized into thr...
