Midterm Outcomes and Risk Stratification after Endovascular Therapy for Patients with Critical Limb Ischaemia due to Isolated Below-the-knee Lesions

Abstract Objectives To assess and risk stratify midterm clinical outcomes after endovascular therapy (EVT) by angioplasty only of patients with critical limb ischaemia (CLI) due to isolated below-the-knee (BTK) lesions. Design Retrospective multicenter study. Materials and methods Between March 2004...

Description
Summary:Abstract Objectives To assess and risk stratify midterm clinical outcomes after endovascular therapy (EVT) by angioplasty only of patients with critical limb ischaemia (CLI) due to isolated below-the-knee (BTK) lesions. Design Retrospective multicenter study. Materials and methods Between March 2004 and October 2010, 465 limbs (Rutherford 5 and 6: 79%) from 406 patients were studied. Overall survival, limb salvage, and re-intervention were examined out to 3 years by the Kaplan–Meier method and the log-rank test. Their independent predictors and risk stratification were analysed. Results Patient age was 71 ± 11 yrs, with 69% diabetics and 60% on dialysis. Mean follow-up was 18 ± 15 months. Overall survival was 76 ± 2 and 57 ± 4% at 1 and 3, years, respectively. Survival predictors were body mass index
