Vascular surgical audit during a 5-year period. Steering committee on behalf of the Swedish Vascular Registry (Swedvasc).
The objective was to explore possible time trends in the indications for peripheral vascular surgery in Sweden.


METHODS
Analysis of data from the Swedvasc vascular registry 1987-1991.


METHODS
Routine vascular surgery in university, county and district hospitals within the Swedish public hospital system. The registry is independent of local administration, run by the surgeons themselves and financed by national authorities.


METHODS
4950 procedures registered in the 17 original centres 1987-91 and 1892 procedures registered in 16 new centres 1991.


METHODS
Distribution of indications, mortality within 30 days and clinical outcome at one year.


RESULTS
During the first 5 years of the registry (1987 to 1991) the proportion of procedures performed for acute ischaemia significantly decreased from 20% to 14.3%. Simultaneously procedures for critical leg ischaemia significantly increased from 24.8 to 30.3%. Changes in the proportions treated for aortic aneurysms, carotid artery stenosis, claudication, vascular access or other indications were less striking or nonsignificant. The 30-day mortality decreased in patients operated on for acute ischaemia but did not change in other groups. The proportion of elective/emergency operation for aortic aneurysm changed from 1.2 to 2.0 leading to a minimal decrease in overall aneurysm mortality. The proportion of patients treated for claudication who were alive and improved at one year changed from 77.2% to 72.9% which was not statistically significant, while the proportion of patients treated for critical ischaemia who were alive with an intact leg after one year increased from 65.2% to 80.2% which was a significant improvement.


CONCLUSIONS
Decision making among vascular surgeons in Sweden appears to have improved as proportionally fewer patients are operated on for acute ischaemia, more for critical ischaemia with possibly an improved outcome.
