Open research questions in Peripheral Artery Disease Management

29 unresolved questions extracted from the limitations and future-work sections of 243 Peripheral Artery Disease Management papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • In this cross-sectional analysis, limb-threatening severity was associated with the chronic vascular-metabolic phenotype rather than with the measured admission laboratory profile, which did not separate the severity groups; a leucocyte differential was not recorded, so the neutrophil-to-lymphocyte ratio could not be assessed.

    Chronic disease burden, not admission laboratory results, marks limb-threatening severity in acute lower-limb arterial thrombosis: a registry study of 288 patients from Kazakhstan · 2026 · DOI

  • However, considering the limited studies available and overall small sample size, further trials are necessary to understand the relationship between this novel therapy and CLTI management.

    Comparison of Tibial Transverse Transport Angiogenesis Versus Vascular Surgery in Patients with Chronic Limb Threatening Ischemia: A Systematic Review and Meta-Analysis · 2026 · DOI

  • The primary limitations of this study include the small sample size, which restricts the statistical power of the results, and the lack of a control group (per es, versus CO2) for direct comparison. How- ever, clinical experience remains sparse, and unresolved challenges regarding standardized dosing and imaging protocols currently hinder the widespread adoption of GBCAs in routine practice [22]. Further comparative studies are warranted to validate these find- ings on a larger scale.

    Feasibility pilot study of the use of ultra-low dose iodinated contrast agent for endovascular procedures in patients with chronic limb-threatening ischemia and renal impairment: the ULTRA-LOW study · 2026 · DOI

  • Pedal acceleration time (PAT) has recently attracted clinical interest for assessing peripheral arterial disease (PAD), particularly in patients in whom ankle–brachial index (ABI) or toe pressure measurements are unreliable or not feasible, yet its diagnostic worth has not been systematically evaluated.

    Pedal Acceleration Time as a Marker of Limb Perfusion: A Systematic Review and Correlation Meta-Analysis · 2026 · DOI

  • The CRP-to-albumin ratio (CAR) has emerged as a composite inflammatory-nutritional biomarker with prognostic value in various cardiovascular conditions, yet its association with peripheral artery disease (PAD) in the general population remains underexplored.

    The prognostic value of the CRP-albumin ratio for peripheral artery disease: A cross-sectional study from the National Health and Nutrition Examination Survey · 2026 · DOI

  • The place of DUS with waveforms (DWs) analysis to estimate distal perfusion remains poorly known even if many consider it a helpful tool to evaluate PAD severity through distal perfusion.

    Role of Tibial Acceleration Time in Predicting Limb Salvage in Critical Limb Ischemia · 2024 · DOI

  • Further prospective randomized controlled trials are warranted to further support BFRT safety; however, from this literature review, it can be concluded that BFRT can be utilized safely in the proper patient population when administered by qualified professionals who have undergone the appropriate training.

    Overall Safety and Risks Associated with Blood Flow Restriction Therapy: A Literature Review · 2022 · DOI

  • Background: The clinical benefit and safety of drug-coated devices in chronic limb-threatening ischemia remain debated, particularly after recent randomized evidence questioning paclitaxel-coated technologies.

    Drug-Coated Devices, Wound Healing, and Mortality After Endovascular Therapy for Chronic Limb-Threatening Ischemia · 2026 · DOI

  • Acute lower-limb arterial thrombosis is a vascular emergency that often reaches internists and emergency physicians before a vascular specialist, and data from Central Asia are scarce.

    Chronic disease burden, not admission laboratory results, marks limb-threatening severity in acute lower-limb arterial thrombosis: a registry study of 288 patients from Kazakhstan · 2026 · DOI

  • The optimal revascularization strategy for common femoral artery (CFA) atherosclerotic occlusive disease remains debated.

    Endovascular Therapy Versus Open Surgery for Common Femoral Artery Atherosclerotic Occlusive Disease: A Systematic Review and Meta-Analysis · 2026 · DOI

  • Further investigation of this topic across different geographic regions and clinical settings will undoubtedly deepen our un- Güner, et.

    Mapping the publications on the thyroidea ima artery with Vosviewer · 2026 · DOI

  • Although endovascular therapy has become the preferred treatment modality, the optimal access strategy for unilateral CIA CTO remains uncertain.

    Planned first-line bilateral femoral access for endovascular treatment of unilateral common iliac artery chronic total occlusion: procedural control and outcomes · 2026 · DOI

  • Evidence in non-femoropopliteal and dialysis access applications remains sparse and largely case-based, limiting firm recommendations beyond core indications.

    Supera Stent for Peripheral Arterial Disease: Scoping Review with ☸️SAIMSARA · 2026 · DOI

  • These findings highlight an important limitation of a vein-first strategy in routine practice and support standardized bilateral mapping to clarify conduit availability and guide individualized revascularization planning.
