Directional Atherectomy Is Associated with Better Long-Term Efficiency Compared with Angioplasty for Common Femoral Artery Occlusive Disease in Rutherford 2-4 Patients.

ABSTRACT

BACKGROUND: Despite increased interest in treating common femoral artery (CFA) with endovascular technology, there are little data regarding the long-term outcomes of different endovascular treatment modalities. We report the results after endovascular therapy of symptomatic obstructions of the CFA in a single center. METHODS: We retrospectively reviewed the records of consecutive patients with eligible CFA lesions who were treated with endovascular methods between 2011 and 2013. The preoperative demographic operative details and postoperative outcomes were compared and statistically analyzed. RESULTS: Ninety patients with CFA lesions were treated, and 76 (84.4%) completed a follow-up. Claudication was present in 62 of 76 (81.6%) patients, and stenosis was present in 60 of 76 (78.9%) patients. Angioplasty was performed in 45 patients, and atherectomy was performed in 31 patients. There was no significant difference in the preoperative demographic data, procedure time, contrast administration, or length of hospital stay between the 2 groups. In-hospital treatment costs were significantly higher in the atherectomy group (69,822 RenMinBi Yuan vs. 49,078 RenMinBi Yuan; P = 0.043). During the 4-year primary patency, for whole group or bifurcated/claudicant subgroup, all patients within the atherectomy group were significantly better than those in the angioplasty group. CONCLUSIONS: Atherectomy may be a better alternative to angioplasty for CFA atherosclerotic obstructions lesions. Compared with angioplasty, atherectomy seems to have better results in bifurcated lesions or claudicant patients. In diabetic patients, no superiority was found on either patency or improvement in walking distance.
