Abstract
The trend towards subspecialisation in hospital services is likely to lead to the development of vascular surgery as a separate specialty. If vascular surgery is to emerge as a high quality service then vascular emergencies--a substantial component of the workload--should be dealt with by surgeons with adequate training, and all patients should have equal access to the service. A specialist vascular surgical unit would have to be large enough to make efficient use of other services that it needs, such as radiology, and so may require the amalgamation of smaller health district units. Because of the differing local degrees of subspecialisation, national or regional strategies for vascular surgery must be developed.
