Abstract
The complexity of critical limb ischemia (CLI) requires dedicated multidisciplinary teams of different care providers, who will supervise the full cycle of CLI care. Until CLI treatment is fully centralized, such dedicated teams may work as second-opinion tools before major amputation is undertaken in CLI patients. The aim of the study is to assess the effectiveness of a well-timed referral to a dedicated CLI-center of patients scheduled to major amputation elsewhere. A retrospective analysis of all CLI-patients treated in our department between January 2019 and March 2020 was conducted. Only patients scheduled for a major amputation elsewhere and referred to our clinic were included. Primary endpoint was amputation-free survival, whereas technical success, limb salvage, minor amputation rate, re-admission at 30 days, and frequency of medication change from other disciplines were the secondary endpoints. Sixteen patients with 19 treated limbs were identified and included in this analysis. The WIfI (wound, infection and foot ischemia) clinical stage on admission was 2 in 4 limbs (21%), 3 in 5 limbs (26%), and 4 in 10 limbs (53%). All patients underwent advanced endovascular revascularization. Minor amputation was performed in 8 patients (42%). Amputation-free survival at 6 months was 93% with limb salvage rate of 100%. Technical success and re-admission rates at 30 days was 95% and 6%, respectively. There was a medication adjustment from other specialties in 13 (81%) patients. Patients in severe stages of CLI scheduled to major amputation reached high limb salvage and survival rate, since they are referred for a second opinion to a dedicated multidisciplinary CLI team.
