ABSTRACT
OBJECTIVE:
We evaluated limb salvage (LS), amputation-free survival (AFS), and target extremity reintervention (TER) after plain old balloon angioplasty (POBA), stenting, and atherectomy for treatment of infrapopliteal disease (IPD) with chronic limb-threatening ischemia (CLTI).METHODS:
All index peripheral vascular interventions for IPD and CLTI were identified from the Vascular Quality Initiative registry. Of the multilevel procedures, the peripheral vascular intervention type was indexed to the infrapopliteal segment. Propensity score matching was used to control for baseline differences between groups. Kaplan-Meier and Cox regression were used to calculate and compare LS and AFS.RESULTS:
The 3-year LS for stenting vs POBA was 87.6% vs 81.9% (P = .006) but was not significant on Cox regression analysis (hazard ratio [HR], 0.91; 95% confidence interval [CI], 0.56-0.76; P = .08). AFS was superior for stenting vs POBA (78.1% vs 69.5%; P = .001; HR, 0.73; 95% CI, 0.60-0.90; P = .003). LS was similar for POBA and atherectomy (81.9% vs 84.8%; P = .11) and for stenting and atherectomy (87.6% vs 84.8%; P = .23). The LS rate after propensity score matching for POBA vs stenting was 83.4% vs 88.2% (P = .07; HR, 0.71; 95% CI, 0.50-1.017; P = .062). The AFS rate for stenting vs POBA was 78.8% vs 69.4% (P = .005; HR, 0.69; 95% CI, 0.54-0.89; P = .005). No significant differences were found between stenting and atherectomy (P = .21 for atherectomy; and P = .34 for POBA). The need for TER did not differ across the groups but the interval to TER was significantly longer for stenting than for POBA or atherectomy (stenting vs POBA, 12.8 months vs 7.7 months; P = .001; stenting vs atherectomy, 13.5 months vs 6.8 months; P < .001).CONCLUSIONS:
Stenting and atherectomy had comparable LS and AFS for patients with IPD and CLTI. However, stenting conferred significant benefits for AFS compared with POBA but atherectomy did not. Furthermore, the interval to TER was nearly double for stenting compared with POBA or atherectomy. These factors should be considered when determining the treatment strategy for this challenging anatomic segment.Palavras-chave
