Abstract

Background: Subintimal endovascular intervention has been used widely in the treatment of symptomatic superficial femoral artery (SFA) occlusion. The relative effectiveness of subintimal placement of a covered stent (CS) versus balloon-only subintimal angioplasty (SIA) remains uncertain. Methods: We performed a retrospective cohort study of consecutive patients with symptomatic SFA occlusions (>15 cm) who underwent subintimal endovascular intervention, either CS or SIA, in a single institution. Primary patency was the primary outcome. Secondary outcomes included complication rates, freedom from re-intervention, and limb salvage rates. Patency was ascertained with followup duplex or clinically. Results: We evaluated 57 patients in the SIA group and 31 patients in the CS group. At 1 year the SFA primary patency for the SIA and CS groups was 28% versus 75% (P < .001), whereas the primary assisted patency was 37% versus 84% (P < .001), respectively. Need for bypass was 13% versus 0% (P = .05) in the SIA and CS groups, respectively. Conclusions: Placement of a covered stent improves patency after subintimal intervention for long SFA occlusion.
