Abstract
Over a 17-year period, 2930 vascular procedures were performed for chronic lower-limb occlusive disease. During this time, the total vascular surgical workload rose significantly as a result of an increase in the rates of arterial reconstruction and percutaneous transluminal angioplasty. Although the major lower-limb amputation rate did not change significantly, there was a decrease in the above- to below-knee ratio. In addition, there were significant increases in the percentage of patients treated over the age of 75 years and the proportion of attempted revascularizations before amputation. The mortality rates for arterial reconstruction, percutaneous transluminal angioplasty and amputation did not change significantly during the study period. The duration of hospital stay increased significantly for patients undergoing amputation and decreased significantly for those receiving arterial reconstruction.
