Acute nontraumatic extremity ischaemia in Sweden. A one-year survey.
An attempt was made to evaluate the results of treatment for acute nontraumatic extremity ischaemia in Sweden during one year. A questionnaire was sent to all surgical units, and 61% replied. Of the total 586 evaluated cases, 497 were classified as embolism and 89 as acute thrombosis. Patient age strongly influenced results in both groups as regards limb salvage and mortality rates. The site of embolic occlusion also influenced mortality, with greatly heightened rate in aortic occlusion. Delay of operation for more than 12 hours after onset of symptoms was associated with increase in amputation rate and mortality. Adequate heparin therapy significantly improved results after embolectomy, but had no such effect after surgical treatment of thrombosis. The amputation rate was higher after acute thrombosis than after embolism. The authors conclude that patient age should be considered in comparisons between different case series of acute ischaemia, that embolus site and time of surgery are important determinants of mortality and amputation rate, and that heparin significantly improves results of embolectomy.[1]References
