title: Coronary-like revascularization for atherosclerotic renal artery stenosis--results in 181 consecutive patients.
abstract: OBJECTIVE
  The aim of this study was to document the early outcome of coronary-like revascularization for atherosclerotic renal artery stenosis (ARAS).
  
  
  RESULTS
  A total of 181 consecutive patient, 102 men, mean age 66.1 (+/- 9.2) years and 79 females, mean age 68.4 (+/- 9.2) years and 198 lesions were treated between February 1999 and May 2004 for ARAS and retrospectively analyzed. At least one major cardiovascular risk factor was present in 179 (98.9%) patients. Pre-dilatation ARAS was 81.3+/-9.6%, 27 ARAS were 50-70% and no ARAS was <50%. 135 (68.2%) of the ARAS lesions were ostial and 63 (31.8%) were non-ostial. In 17 (9.4%) patients bilateral ARAS were present. Technical success defined as residual stenosis < or =30% was achieved in 178 (98.3%) of patients and 195 (98.5%) of lesions. In one patient (0.5%) the target ARAS could not be crossed, in two (1.1%) patients residual stenosis was >30%. No major adverse cardiac or cerebral effects were observed. In 3.9% of patients minor local complications of the access site occurred; 4 (2.2%) inguinal hematoma, 3 (1.7%) pseudoaneurysm were documented. Serum creatinine concentrations and systolic and diastolic blood pressure before and after the intervention were not statistically different.
  
  
  CONCLUSIONS
  Coronary-like approach to ARAS revascularization is technically feasible and associated with a very low complication rate.
