Article Synopsis
  • The study assessed the safety and effectiveness of catheter-directed thrombolysis (CDT) using rt-PA in patients with symptomatic peripheral artery disease from January 2013 to December 2020.
  • Of the 1238 patients treated, serious adverse events occurred in 41.3%, with bleeding being the most common complication at 25.4%, and notable rates of limb salvage at 91.6% and 88.8% after 12 and 24 months, respectively.
  • Key predictors for complications included increasing age, the use of certain medications (abciximab and alprostadil), and the duration of the lysis treatment, highlighting a significant risk associated with CDT despite its high success rate.

Background: When antegrade recanalization of femoropopliteal and/or infrapopliteal occlusions fails, retrograde access has become an established option. To evaluate the results of combined antegrade and retrograde recanalization of femoropopliteal and infrapopliteal occlusions, patients undergoing secondary retrograde recanalization attempts were analyzed retrospectively.

Methods: The primary end point was the success of the procedure (successful occlusion crossing using the antegrade/retrograde technique).

Background: The femoropopliteal arteries are commonly affected by atherosclerotic lesions. The use of atherectomy may increase the benefit of definitive therapy, such as drug-coated balloon (DCB) angioplasty.

Purpose: To analyze the 2-year safety and efficacy of atherectomy in general and stratified by directional atherectomy (DA) and front-cutting atherectomy (FA) for the treatment of atherosclerotic lesions of the femoropopliteal arteries.

Objective: To evaluate the safety and effectiveness of drug-coated balloon angioplasty (DCB) in isolated popliteal lesions.

Background: The benefit of using DCB in femoropopliteal arteries including the proximal popliteal artery has been demonstrated, but has not yet been evaluated for isolated popliteal lesions.

Methods: This retrospective, single-center study includes patients requiring treatment with DCB of isolated popliteal lesions.

Purpose: To evaluate the potential differences in characteristics of femoropopliteal in-stent restenosis (ISR) stratified by stent design with a focus on the swirling flow-inducing BioMimics 3D helical centerline stent.

Methods: Patients with ISR of the superficial femoral and popliteal arteries undergoing reintervention were included in this study. The primary endpoint was the angiographic localization and extent of restenosis or reocclusion with the following five different stent systems: SMART Control stent, Supera peripheral stent, GORE VIABAHN endoprosthesis, BioMimics 3D stent, and Zilver PTX stent.

In addition to manual compression, various vascular closure devices (VCD) are available to seal the puncture site following arterial vascular procedures. To evaluate the efficacy and safety of the extravascular MYNX CONTROL closure system for achieving primary hemostasis after femoral arterial access following peripheral arterial procedures, compared to the intravascular FemoSeal Aclosure system. A retrospective analysis of consecutive patients who underwent endovascular intervention between April and November 2022 was performed.
