The Prognostic Value of the SVS WIfI Classification in Patients with Critical Limb Ischemia: A Systematic Review

Abstract

We pooled IPD from 11 of 32 eligible studies. From the remaining 21 studies, IPD could not be retrieved because of no response (n¼7), no IPD available (n¼12) and data from randomized controlled trial (n¼2) which resulted in a response rate of >75%. The total patient cohort consist of 703 patients of which 334 (48%) were treated with a carotid endarterectomy (CEA), 227 (32%) with carotid artery stenting (CAS) and 142 (20%) with BMT. Within 30 days, any stroke/death was reported in 8 patients (2.4%) in the CEA group, in 5 patients (2.2%) in the CAS group, and in 7 patients (4.9%) in the BMT group. These results were not significantly different between the three groups. Long-term outcome analysis will be available at the time of the ESVS conference. Conclusion-Based on these preliminary results, procedural outcome of CEA or CAS was within ranges of revascularization in low risk patients. However, outcomes of CEA or CAS were not significantly different from BMT treatment. Long-term outcome analysis will be available at the time of the ESVS conference.
