Effect of preimplant endovascular debulking strategies on the deployment of nitinol self-expanding stents in superficial femoral arteries
Background
The effect of debulking on nitinol self-expanding (n-SES) stent deployment in the superficial femoral artery (SFA) has never been systematically assessed.
Objective
The objective was to evaluate hemodynamic differences in stented SFA segments, debulked or dilated by conventional balloons prior to n-SES implants.
Objective
The objective was to evaluate hemodynamic differences in stented SFA segments, debulked or dilated by conventional balloons prior to n-SES implants.
Methods
We evaluated 86 n-SES stents in 46 limbs of 40 unique patients. Comparisons between the two groups were made by measuring the peak systolic velocity ratios (PVRs) within stented segments (by duplex ultrasound). Resting ankle–brachial indices (ABI) and normalized difference between expected and measured stent diameters (NDEMD) were also assessed. The aforementioned measurements were obtained at <24 h (100% of limbs), 6 months (54.3% of limbs) and 1 year (54.3% of limbs) postprocedure.
