Abstract
BACKGROUNDAngioplasty of chronically totally occluded vessels has been associated with a success rate well below and restenosis rate well above that for angioplasty of stenosed segments. However, long-term clinical outcome after successful revascularization of a chronically totally occluded vessel has not been reported in detail.METHODS AND RESULTSAccordingly, data for 480 patients undergoing angioplasty for chronic total occlusion at Emory University Hospital, Atlanta, Ga., from 1980 to 1988 were analyzed for predictors of in-hospital procedural and clinical (procedural success and absence of in-hospital complications) success, restenosis, and 4-year clinical follow-up. The study population was grouped by procedural and clinical success and failure. The groups were then compared for outcome, both in hospital and long term. The initial clinical success rate was 66% (317 of 480 patients). Independent correlates of failure were the number of vessels diseased (p less than 0.001), vessel location of the lesio...Keywords
