Outcomes of hybrid procedures for peripheral arterial disease: 5-year single center experience.

Abstract

The objective of the study was to present patients with peripheral vascular disease (PVD) who underwent hybrid procedures at our institution, the results of these interventions for a 5-year period and determine patency, mortality, failure, and amputation rates compared to the literature. Observational, single center, retrospective, and cross-sectional study which analyzed data gathered from the vascular quality initiative from patients who had hybrid revascularization procedures from January 2010 to December 2015. 87 patients were identified: 51 (58%) male, 36 (41%) female, 9 (10%) had critical limb ischemia (CLI), and 78 (90%) claudication. We analyzed results of hybrid interventions in their variations. Technical success rate was 100%, patency at 2 years 88.5% (primary 65%, primary-assisted 18.3%, and secondary 4.5%) and 11.49% failure rate (lost patency < 1 year, conversion to open or/and amputation). Predictors of failure were: Female, previous chronic heart failure, longer length of stay, and previously transferred from another hospital. Amputation rate was 12.6% (10.3% major and 2.2% minor amputation), the only significant predictor was age (p = 0.035, odds ratio = 0.89) (0.806-99). Hybrid procedures are effective to treat patients with either CLI or claudication. Our study had outcomes comparable to the literature, with similar patency, amputation, and complication rates. We conclude it is a safe and effective option for PVD with multi-level disease.
