The Society of Interventional Radiology's (SIR) 2025 Annual Scientific Meeting, held from March 29 to April 2, 2025, in Nashville, Tennessee, commemorated SIR's 50th anniversary. This milestone event convened over 5,000 interventional radiologists, trainees, diagnostic radiologists, and related healthcare professionals. The meeting featured more than 400 oral presentations and over 250 poster presentations of peer-reviewed scientific abstracts, emphasizing advancements in minimally invasive, image-guided treatments aimed at enhancing patient care.
Among the diverse range of topics presented, several research posters provided valuable insights into the management of peripheral artery disease (PAD). These studies highlighted innovative approaches and emerging methodologies in interventional radiology, reflecting the ongoing commitment to improving outcomes for PAD patients.
Twelve Years of Peripheral Vascular Interventions (PVIs): An Analysis of Trends from 2011-2022
- This study tracks the trends in the use of Peripheral Vascular Interventions (PVIs) across specialties (interventional radiologists, interventional cardiologists, vascular surgeons, and other providers) and settings (OBLs, ASCs, outpatient, and inpatient hospitals) from 2011-2022. Physician market share changes over time, particularly for IRs, VS, and ICs, are analyzed alongside the shift in the location of care.
- Over the 12-year period, IRs saw a growth in market share, while the overall volume of PVIs in outpatient and inpatient hospital settings decreased. In contrast, the use of outpatient settings like OBLs and ASCs surged dramatically, suggesting a shift towards outpatient procedures. This trend is likely driven by reimbursement policy changes favoring outpatient care.
Trend in Utilization of IVUS among Patients with Peripheral Artery Disease or Critical Limb Threatening Ischemia in the United States
- This study analyzes the increasing use of intravascular ultrasound (IVUS) from 2005 to 2020 in patients with Peripheral Artery Disease (PAD) or Critical Limb Threatening Ischemia (CLTI). It assesses the association between IVUS utilization and various patient outcomes in inpatient settings, including length of stay and discharge status.
- IVUS use increased consistently over the 16-year period, leading to shorter hospital stays and fewer discharges to other facilities. Interestingly, Black patients had lower odds of receiving IVUS compared to White patients. Despite no difference in in-hospital mortality, IVUS use provides valuable clinical benefits, particularly in improving discharge outcomes and reducing hospital length of stay.
Clinical Outcomes Following Lower Limb Angioplasty in Patients with Critical Limb Ischemia
- This study reviews the clinical outcomes of 1,740 patients who underwent angioplasty for Critical Limb Ischemia (CLI) at Singapore General Hospital between 2019-2024. The study focuses on limb salvage rates, survival rates, and post-procedural complications, including factors that affect outcomes.
- Angioplasty was found to be a safe and effective treatment for CLI, with high limb salvage and survival rates at 30 days, 6 months, and 1 year. Key predictors of poor outcomes include advanced age, dialysis dependency, and comorbidities like coronary artery disease and heart failure, which should be considered when evaluating CLI patients for angioplasty.
Common Femoral Artery Occlusive Disease in Chronic Limb Threatening Ischemia: An Analysis of Patient Outcomes and Technical Success with Endovascular Treatment
- This study investigates the safety, efficacy, and short-to-mid-term outcomes of endovascular therapy for common femoral artery (CFA) occlusion in patients with Chronic Limb Threatening Ischemia (CLTI). Data from 53 patients treated between 2021-2024 is analyzed, focusing on technical success, symptom improvement, and complications.
- Endovascular treatment of CFA disease yielded excellent technical success (100%) and symptom improvement (94%) for most patients, making it a reliable first-line option, especially for those ineligible for surgery. Long-term outcomes are promising, but further studies are needed to compare endovascular management with the gold standard of endarterectomy.
Mechanical Aspiration Thrombectomy in the Treatment of Acute Limb Ischemia – A Real World Single-Center Safety and Efficacy Analysis
- This single-center study examines the efficacy and safety of mechanical aspiration thrombectomy as a first-line treatment for Acute Limb Ischemia (ALI). The study compares outcomes for 55 patients treated with thrombectomy to other methods, focusing on technical success, complications, and in-hospital mortality rates.
- Mechanical aspiration thrombectomy demonstrated high technical success (87%) and low complication rates (3.6% major amputation and 1.8% mortality), making it an effective first-line therapy for ALI. This approach offers a promising alternative to thrombolysis or surgery, though further studies are needed to assess long-term outcomes and its cost-effectiveness compared to other treatments.
Retrograde Peroneal Artery Access for Arterial Flossing: A Single-Center Experience
- This study reports the use of retrograde peroneal artery access for arterial flossing in 20 patients with Chronic Limb Threatening Ischemia (CLTI) between 2012-2024. The technique is applied when other tibio-pedal access options are unavailable, and outcomes such as revascularization success, complication rates, and 6-month follow-up are assessed.
- Retrograde peroneal artery access, combined with arterial flossing, demonstrated high technical success (95%) and effective limb salvage, with promising long-term outcomes in patients who had no other viable access options. The technique was safe with minimal complications, though more extensive follow-up and long-term data are required to validate its role as a durable revascularization option.
