title: Carotid endarterectomy in Great Britain and Ireland: practice between 1984 and 1992.
abstract: Of 356 questionnaires on carotid endarterectomy sent to all vascular surgeons in Great Britain and Ireland likely to undertake this procedure, 326 (92 per cent) were returned. Of those who replied 131 (40 per cent) performed at least one carotid endarterectomy in 1992; 57 (44 per cent) of these carried out ten or fewer operations and 74 (56 per cent) more than ten. The 131 surgeons were collectively responsible for 2628 operations in 1992, twice as many as were undertaken in either 1984 or 1989, years for which similar survey data are available. This sharp rise in the number of operations was accounted for by increased activity on the part of experienced operators, rather than any rise in the number of 'occasional' carotid surgeons. In 1992, although the neurologist remained a major source of patient referral, general practitioners (and others) were also referring patients in large numbers direct to the vascular surgeon; this represents a change in practice compared with previous years. Many of the technical aspects surrounding carotid endarterectomy remained unchanged over the years surveyed (1984, 1989, 1992) but by 1992 duplex scanning, intra-arterial (but not intravenous) digital subtraction angiography and transcranial Doppler ultrasonography had become established as clinically useful techniques.
