title: Trends in the practice of arterial surgery in Western Australia.
abstract: An overview of arterial surgery in Western Australia and the Department of Vascular Surgery at Royal Perth Hospital was undertaken for the ten year period from 1983 to 1992. The annual number of arterial procedures increased 116% from 937 to 2027 and lower limb amputations increased 44% from 335 to 483. Five arterial procedures were examined in detail. There was a marked increase in carotid endarterectomy and angioplasty, a moderate increase in aortic aneurysm repair and a small increase in aortofemoral and femoropopliteal bypass surgery. The major amputation rate was not influenced by bypass surgery. It rose from 113 per million population in 1983 to a peak of 148 in 1986, and then fell to 113 per million population in 1992. From June 1982 to June 1992 the population of Western Australia rose 24%, from 1.34 to 1.66 million (and for persons 60 years and over, rose 38% from 0.16 to 0.23 million). At Royal Perth Hospital similar trends were observed. Mean duration of operation for all vascular procedures and for the individual procedures of carotid endarterectomy, angioplasty, aortic aneurysm repair and aortofemoral and femoropopliteal bypass remained unchanged. Average length of stay decreased for carotid endarterectomy (29%) and angioplasty (74%), but remained unchanged for aortic aneurysm repair and aortofemoral and femoropopliteal bypass.
