title: 15 year experience of carotid endarterectomy at the Royal Brisbane and Women's Hospital: outcomes and changing trends in management.
abstract: OBJECTIVE
  The aim of this study was to review the results of carotid endarterectomy (CEA) at the Royal Brisbane and Women's Hospital (RBWH) to provide a benchmark for comparison with carotid stenting and to document changes in imaging and procedural techniques over time.
  
  
  METHODS
  Analysis of RBWH CEA database from 1992 to 2007.
  
  
  RESULTS
  1313 consecutive patients (average age 69.2 years, 9% 80 years or older, 69% males) underwent carotid endarterectomy at the RBWH between 1992 and May 2007. Indication for surgery was symptomatic disease in 67%. Preoperative investigations included a duplex scan in 97%, an angiogram in 24% and a CT brain in 33%. Angiogram related neurological events occurred in 3.5% of patients (1.6% stroke, 1.9% TIA). There were 7 deaths (0.5%) and 28 strokes (2.1%) for a combined stroke and death rate of 2.4%. The rate of transient ischemic attacks was 1.1%. Gender patch use and trainees operating with the surgeon unscrubbed predicted a higher combined stroke and death rate. Trends over time included: reduction in preoperative angiography from 66% to <5% and increased rate of patching from 39% to approximately 100%.
  
  
  CONCLUSIONS
  Performance of CEA at the RBWH is in keeping with published literature standards. There has been an evolution to surgery performed on the basis of duplex ultrasound alone and an almost universal use of patching.
