Endovascular repair is a feasible option for superficial femoral artery injuries: a comparative effectiveness analysis.

Abstract

To compare outcomes between open (OR) and endovascular repair following superficial femoral artery (SFA) injuries. This is a cross-sectional study querying the 2012-2014 National Inpatient Sample for SFA injuries. Patients were grouped into OR and stent-graft placement (SGP). Primary outcome was in-hospital mortality. Secondary outcomes included hospital length of stay (HLOS), fasciotomy and amputation rate, and cost. Wilcoxon rank-sum, Kruskal-Wallis, Chi-squared test with Bonferroni adjustment were used as appropriate; p < 0.05 was significant. 255 Patients were identified. Mean age was 34.6years and majority were males. OR was performed in 82.7%. Overall mortality rate was 3.7%. Median HLOS was 8days. Fasciotomies were performed in 31% and lower limb amputations in 3.7%. Males more often underwent OR (89.0% vs. 73.1%, p < 0.01). SGP patients were significantly older (44.9 vs. 32.5years; p < 0.01), and with Medicare insurance (20.5% vs. 6.5%; p < 0.01. Mortality, HLOS, and hospitalization cost were not significantly different. OR patients had higher rate of fasciotomy (35.4% vs. 15.4%; p < 0.01). Endovascular management is not inferior to OR following SFA injuries and both carry a low amputation rate. OR is associated with a higher fasciotomy rate. Endovascular repair should be considered when technically feasible.
