Abstract/OtherAbstract:
BACKGROUND: The technique of long segment stenting of the superficial femoral artery (SFA) has been associated with poorer short- and long-term results. The full metal jacket (FMJ) stenting is typically described as long segment continuous stenting of a vessel segment. Initially, this technique was described in percutaneous coronary interventions. However, until recently, FMJ of the SFA has not been studied. We examined our experience with FMJ of the SFA to evaluate the outcomes and the safety of this technique.
METHODS: Retrospective data were gathered for peripheral angioplasties and stenting for the period between January 2005 and December 2008. The cases involving FMJ stenting of the SFA were identified by angiographic findings and the operative dictations providing the stent data. Selective FMJ stenting of the SFA was performed for the residual stenosis after balloon angioplasty of the SFA because of either dissection or significant recoil. The cases with concomitant iliac artery angioplasty and/or stenting were excluded from the data set for analysis. The variables for the evaluation were primary patency rate, mortality rate, and limb salvage rate, which were stratified on the basis of the risk factors.
RESULTS: A total of 63 cases involving FMJ stenting of the SFA were identified from the database of 707 patients who had peripheral endovascular interventions between January 2005 and December 2008. Average age of the patients was 70 years (range: 52-104 years, SD: 10.1 years). There were no transatlantic inter-society consensus (TASC) A lesions, 11% (7/63) of the lesions were TASC B, 68% (43/63) were TASC C, and 21% (13/63) were TASC D. The median primary patency rate was 9 months (95% CI: 5.06-12.94). The mortality rate was 4% at 6-month follow-up. The limb salvage rate was 85.7%. In all, 65% (41/63) of the patients were claudicants, whereas 23% (15/63) had intervention for some form of tissue loss (ischemic ulcer, gangrene). Associated infrapopliteal intervention was performed in 15.9% of the patients. Average creatinine level was 1.67 (range: 0.7-10.9, SD: 2.03) and 49% (31/63) of the patients had diabetes. The average 6-month patency rate was 55% (SD: 0.5). Multivariate logistic regression analysis showed that diabetes (OR: 0.33, p = 0.044, 95% CI: 0.11-0.97) and a creatinine level of ≥1.6 (OR: 0.16, p = 0.038, 95% CI: 0.03-0.9) were the independent risk factors for loss of patency in <6 months.
CONCLUSION: Our experience suggests promising results for the technique of FMJ of the SFA and also that further examination of the technique is warranted.
