Trends in vascular surgery since the introduction of percutaneous transluminal angioplasty

Abstract

Abstract Lower-limb percutaneous transluminal angioplasty (PTA) has been used increasingly over the past decade, either alone or in conjunction with arterial reconstructive surgery. However, its impact on operation rates has not been evaluated properly. Rates of vascular operations and PTAs performed per referral for peripheral arterial disease to the regional vascular service at The Royal Infirmary, Edinburgh, were calculated for the years 1986-1992. The overall rate of PTA for peripheral arterial disease increased ninefold over this period; that for critical ischaemia increased fivefold. Rates of aortic and femoral reconstruction for all peripheral arterial disease increased by 40 and 100 per cent respectively, but rates for critical ischaemia remained static. The major amputation rate rose by 47 per cent between 1986 and 1990, and thereafter reached a plateau. Increased use of PTA was not associated with a reduction in the number of vascular operations.
