Abstract

© 2018 EDIZIONI MINERVA MEDICA. Background: Indications for the revascularization treatment of peripheral arterial disease (PAD) generate much discussion, and practice varies significantly among hospitals. This study looked at patients with PAD admitted to all hospitals of the Catalan Health Service and analyzed patterns of revascularization techniques with subsequent amputation procedures. Methods: We used the clinical-administrative registry of admissions of all patients in the hospitals of Catalonia, north-east Spain, between 2009 and 2014. We analyzed the clinical course of patients admitted with PAD throughout their successive hospital admissions. Variability between hospitals was described for the revascularization techniques and amputations performed. Endovascular outcomes were compared with those from open surgery. Results: Annually, there were 9,828 admissions with PAD and 631 major amputations. Eight hospitals accounted for 52% of all admissions, and endovascular techniques occurred predominantly in high-tech, high-resolution or reference hospitals. The ratio of admissions involving endovascular techniques/open surgery varied from 0.02 to 3.73 according to the hospital, and had a correlation of -0.175 (P=0.447) with the percentage of performed major amputations and of 0.122 (P=0.598) ratio of minor / major amputations. At the end of the 6 studied years, endovascular revascularization resulted in lower patency and more minor amputations than open surgery, but had the same percentage of major amputations (10.3% vs. 10.7%, P=0.526) and lower in-hospital mortality (7.1% vs. 9.5%, P<0.0001). Conclusions: Interventions of PAD are centralized in complex hospitals and have an important variability depending on the treating hospital. Hospital variability in revascularization techniques seems to have no impact on leg salvage. Endovascular and surgical revascularization would result in similar percentages of major amputations.
