Abstract
Surgical audit data for two 5-year periods (1974–78 and 1983–87) have been compared in a Health Board Area to assess the impact of centralization of emergency vascular services on the treatment of the acutely ischaemic lower limb. Patient populations in each period were comparable. Mortality rates remained constant in both periods at approximately 30 per cent. A significant improvement in overall limb salvage was observed (from 54 to 67 per cent, P < 0·05). Limb salvage in survivors was improved from 80 to 95 per cent (P < 0·001) and was paralleled by an increase in the number of reconstructive vascular procedures performed. We concluded that the centralization of emergency vascular services has not led to a reduced risk of mortality but has been associated with improved limb salvage.
