Evaluation of the 4 French Pulsar-18 self-expanding nitinol stent in long femoropopliteal lesions (TASC D II) – 12-month results


  • At 12 months, results of all 36 patients show primary patency (PP) rates of 85.4% and clinically-driven freedom from Target Lesion Revascularization (FTLR) rates of 87.5%.
  • Clinical benefit and improvement of patients' quality of life measured by improvement in Rutherford Class of 1 or more in 97.1% of patients at 12 months; ankle-brachial index (ABI) improved from 0.60 ± 0.10 before the intervention to 0.88 ± 0.08 at 12 months; and pain-free walking distance improved from 56.1 ± 34.9 m before the intervention to 654.2 ± 419.1 m at 12 months (p < 0.0001).
  • This all-comers registry for long femoropopliteal lesions of a mean lesion length of 18.2 cm proved the Pulsar-18 stent's safe usage. Diabetes and renal insufficiency had no negative impact on rates of PP or TLR.

Study Design

Prospective, multi-center, investigator-initiated registry to evaluate the outcome of the implantation of the Pulsar-18 stent in lesions >15 cm in the femoropopliteal arteries.

  • Number of patients (n): 36
  • Principal investigator: Dr. Michael Lichtenberg, Klinikum Arnsberg, Germany
  • Primary endpoint: PP at 6 and 12 months, defined as a binary restenosis on duplex ultrasound (PSVR < 2.5) at the stented target lesion with no clinically-driven TLR (cd-TLR) within the stented segment
  • Secondary clinical endpoints (selected): improvement in resting ABI, improvement in pain-free walking distance, improvement in Rutherford Class, difference in PP in diabetic and renal insufficieny patients, difference in PP of single vs. overlapping stents
