Remote superficial femoral artery endarterectomy and distal aSpire stenting: multicenter medium-term results.
OBJECTIVE
The purpose of this study was to examine the results of remote superficial femoral artery endarterectomy (RSFAE) in conjunction with distal aSpire stenting.


METHODS
RSFAE is a minimally invasive procedure performed through a limited groin incision. Forty patients were included in the study. The indications for the procedure were claudication in 36 patients and limb salvage in 4 patients. RSFAE was performed with the MollRing Cutter device through a femoral arteriotomy. The distal atheromatous plaque was "tacked" with the aSpire stent, which is an expandable polytetrafluoroethylene-covered nitinol stent with high radial strength, yet is flexible and able to withstand compressive forces proximal to the knee joint. Before stent deployment, if the stent position is not optimal it can be wrapped down, repositioned, and re-expanded. Therefore, not only is the plaque end point tacked, but the collateral vessels may be preserved. All patients underwent follow-up examination with serial color-flow ultrasound scanning.


RESULTS
The mean length of endarterectomized superficial femoral artery was 26.2 cm +/- 6.2 cm (range, 13-41 cm). The primary cumulative patency rate by means of life table analysis was 68.6% +/- 13.5% (SE) at 18 months (mean, 13.2 months; range, 1-31 months). During follow-up percutaneous transluminal balloon or stent angioplasty was necessary in 6 patients, for a primary assisted patency rate of 88.5% +/- 8.5% at 18 months. The locations of recurrent stenoses after RSFAE were evenly distributed along the endarterectomized artery. There were no deaths and one wound complication, and mean hospital length of stay was only 2.1 +/- 0.5 days.


CONCLUSIONS
RSFAE with distal aSpire stenting is a safe and moderately durable procedure. If long-term patency rates are similar to those of above-knee femoropopliteal bypass graft, this procedure may prove to be a minimally invasive adjunct for the treatment of superficial femoral artery occlusive disease.
