Background: Elevated lipoprotein(a) [Lp(a)] levels are a causal risk factor for peripheral artery disease. However, data on their effect on delayed wound healing in patients with chronic limb-threatening ischemia (CLTI) are limited. The present study assessed the association between elevated Lp(a) levels and delayed wound healing in patients with CLTI.

Article Synopsis
  • High-dose drug-coated balloons (HD-DCB) and polymer-based drug-eluting stents (PB-DES) are both treatments for femoropopliteal artery disease, showing favorable outcomes in clinical trials, but their comparative effectiveness was unclear.
  • This study analyzed data from 2 large registries with 2470 patients, focusing on the 1-year restenosis rate as the primary endpoint, and additional outcomes like reocclusion rate and major adverse events as secondary endpoints.
  • Results indicated that the 1-year restenosis rate was notably lower for the PB-DES group (16.0%) compared to the HD-DCB group (22.0%), but no significant differences were found in other clinical outcomes

Background: Whether intraluminal drug-coated balloon (DCB) angioplasty is superior to subintimal DCB angioplasty regarding femoropopliteal (FP) chronic total occlusion (CTO) outcomes has not been systematically determined.

Objectives: The aim of this study was to compare the 1-year clinical outcomes of intraluminal and subintimal DCB angioplasty for the treatment of patients with symptomatic FP CTO.

Methods: This subanalysis of POPCORN (Prospective Multi-Center Registry of Drug-Coated Balloon for Femoropopliteal Disease) evaluated 469 lesions in 469 symptomatic patients with lower extremity artery disease who presented with FP CTO and underwent DCB treatment.

  • The study aims to compare the 1-year late lumen loss (LLL) between high-dose (IN.PACT Admiral) and low-dose (Lutonix) paclitaxel-coated balloons used in patients with femoropopliteal lesions.
  • 64 patients with 67 lesions were enrolled, and results showed that the high-dose group experienced significantly lower LLL (0.40 mm) compared to the low-dose group (1.19 mm).
  • Additionally, the high-dose group had a lower rate of binary restenosis (22.2% vs. 50.0%) and demonstrated better outcomes overall despite having longer and more complex lesions.

Purpose: Drug-coated balloon (DCB) has been established as first-line therapy in femoropopliteal (FP) intervention, and successful vessel preparation (VP) is considered a key element. However, the clinical impact of successful VP remains unknown. This retrospective study examined the clinical impact of successful VP in DCB FP intervention.

Purpose: Although the optimal treatment for femoropopliteal (FP) drug-coated balloon (DCB) restenosis lesions remains debatable, the effectiveness of DCB repetition for DCB restenosis has been reported. However, the optimal DCB repetition strategy is not yet established. Thus, this study aimed to compare the clinical outcomes of high-dose DCB repetition with those of low-dose DCB repetition for FP DCB restenosis lesions.

Background: Drug-coated balloons (DCBs) have significantly changed endovascular therapy (EVT) for femoropopliteal artery (FPA) disease, in terms of the expansion of indications for EVT for symptomatic lower extremity arterial disease (LEAD). However, whether there is a difference in the performance among individual DCBs has not yet been fully discussed. The present sub-analysis of real-world data from a prospective trial of first-generation DCBs compared the clinical outcomes between high- and low-dose DCBs using propensity score matching methods.

Clinical trials have demonstrated the efficacy of a balloon-expandable covered stent (CS) for aortoiliac occlusive disease (AIOD). However, the real-world clinical outcomes and the underlying factors remain unclear. We assessed the clinical outcomes and factors associated with primary patency after implantation of a balloon-expandable CS for patients with complex AIOD.

  • This study analyzed the effectiveness of drug-coated balloon (DCB) therapy for treating femoropopliteal lesions, focusing on 1-year freedom from restenosis in a real-world setting.
  • It involved 3,165 patients with varying lesion characteristics and found an 84.5% freedom from restenosis rate at the 12-month mark.
  • Key risk factors contributing to restenosis included prior revascularization, smaller vessel size, severe calcification, chronic total occlusions, low-dose DCB usage, and residual stenosis.

Background: It remains unclear whether the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria could apply to peripheral artery disease (PAD) patients undergoing endovascular therapy (EVT).

Aims: We sought to evaluate the application of the ARC-HBR criteria to PAD patients undergoing EVT with contemporary drug-coated devices (DCD) for femoropopliteal artery lesions.

Methods: Between May 2012 and December 2019, 542 consecutive patients undergoing EVT with DCD for femoropopliteal artery lesions were retrospectively analysed.

Background: The role of catheter-based imaging in peripheral interventions for lower extremity artery disease (LEAD) has increased with percutaneous interventions. To clarify the relation between intravascular ultrasound (IVUS) information and procedure selection strategy for endovascular treatment therapy (EVT) of the femoropopliteal artery in the real-world clinical settings wherein new endovascular technologies (NETs), including drug-coated balloon (DCB), drug-eluting stent (DES), and covered stent-graft (CS). Our retrospective multicenter analysis examined symptomatic 970 patients treated by EVT for de novo femoropopliteal lesions with IVUS guidance.

Background: Elevated lipoprotein(a) (Lp[a]) levels are an independent risk factor for the development of atherosclerotic diseases, including peripheral artery disease (PAD). However, their prognostic impact in patients with PAD remains unknown.

Objectives: The aim of this study was to examine the prognostic impact of elevated Lp(a) levels in patients with PAD undergoing endovascular therapy (EVT).

  • The development of imaging techniques has improved the evaluation of lower extremity artery disease (LEAD) with accurate measurements and visual assessments.
  • There is a need for standardization in these evaluation methods to reduce inconsistencies and risks associated with their use.
  • The Japan Endovascular Treatment Conference (JET) has created a consensus document that outlines standardized approaches for intravascular ultrasound (IVUS), optical frequency domain imaging (OFDI), and angioscopy in endovascular therapy (EVT).

Article Synopsis
  • The study compares the subintimal approach (SA) and the intraluminal approach (IA) in endovascular therapy for chronic total occlusion lesions in the femoropopliteal region, focusing on safety and efficacy.
  • It analyzed data from 500 patients, finding that the 1-year rates of restenosis were similar between the SA and IA groups (41.0% vs. 43.4%).
  • The study concluded that both approaches yielded comparable results after one year, but the subintimal wire passage (SWP) group had a higher rate of perioperative complications compared to the intraluminal wire passage (IWP) group (8.2% vs. 4.1%).

Cholesterol crystal embolism (CCE) is a serious complication that occurs after cardiac and vascular procedures. CCE involves multiple organs, and the prognosis and renal function of patients is poor. Although the efficacy of steroid, statin, and low-density lipoprotein apheresis has been reported, no definitive treatment has been established.

Aim: This study aims to elucidate the effects of early application of target lesion revascularization (TLR) to restenosis lesions of the superficial femoral artery (SFA) without recurrence of symptoms. Despite recent improvements in endovascular therapy (EVT) for the SFA, restenosis remains to be a problem. However, restenosis is not always associated with the recurrence of limb symptoms.
