“…2). As reported previously in nonrandomized studies [20,21,23,24], balloon angioplasty yields acceptable intermediate term results only for treatment of focal disease. Considering primary patency, stenting should therefore be considered as the therapy of choice for intermediate length SFA lesions.…”

“…A sample size of 70-80 patients was estimated necessary assuming a 6-month restenosis rate of 60% in the PTA group [19][20][21] versus 25% in the nitinol stent group [1][2][3]22]. A two-sided P value of 0.05 was considered statistically significant and a power of 80% was required with a 10% maximum drop-out rate.…”

Purpose: To assess the relationship between plasma homocysteine levels and restenosis after femoropopliteal percutaneous transluminal angioplasty. Methods: Over a 10-month period, 128 consecutive, symptomatic patients (72 men; median age 70 years) having successful femoropopliteal angioplasty for atherosclerotic occlusive disease were prospectively enrolled in the study. Plasma homocysteine levels were determined the day before the procedure. The primary endpoint was restenosis >50%, documented by duplex sonography, at up to 12 months' follow-up. Cox proportional hazards analysis was used to determine the risk of restenosis in relation to pretreatment homocysteine levels. Results: The restenosis rate at 12 months was 46%. Median baseline plasma homocysteine levels were not different in patients with and without restenosis (15.4 versus 16.7 μmol/L, p=0.30). Compared to patients with homocysteine levels ≤14 μmol/L (lower tertile, n=43), the hazard ratio of incident restenosis was 0.75 (95% CI 0.40 to 1.40) in patients with homocysteine levels from 14.1 to 19.6 μmol/L (middle tertile, n=42) and 0.64 (95% CI 0.33 to 1.22) in patients with homocysteine levels ≥19.7 μmol/L (upper tertile, n=42) (p=0.38). Multivariate analysis showed that lesion length (p<0.0001) and lack of hypertension (p= 0.0013) were associated with restenosis. Conclusions: Elevated plasma homocysteine levels are not associated with restenosis after femoropopliteal angioplasty. Therefore, plasma homocysteine cannot be considered as an important risk factor influencing the outcome after initially successful angioplasty in femoropopliteal arteries.

“…Restenosis after successful percutaneous transluminal angioplasty (PTA) occurs in approximately 30%-60% of treated limbs [1]. The mechanism of the complex process of intimal hyperplasia and vascular remodeling are increasingly well understood and possible therapeutic agents to inhibit restenosis have been studied in vitro and in animal studies (for review see [2]).…”
