In this episode, Dr. Ally Baheti interviews interventional radiologist Dr. Lorenzo Patrone about his recent multidisciplinary editorial entitled "The 'Woundosome' Concept and Its Impact on Procedural Outcomes in Patients With Chronic Limb-Threatening Ischemia.” --- CHECK OUT OUR SPONSOR Reflow Medical https://www.reflowmedical.com/ --- SYNPOSIS Dr. Patrone explains his interest in critical limb ischemia (CLI) and describes how he reached out to colleagues around the world with the intention of drafting a paper that summarizes research in below-the-ankle interventions and increases awareness of the woundosome concept. He explains the woundosome concept, which aims to understand how each patient’s foot vasculature influences the effectiveness of below-the-ankle interventions and tissue healing. Understanding each patient’s anatomy, having adequate imaging of the foot, obtaining pedal acceleration times, and using micro-oxygen sensors are strategies to assess wound perfusion, which is integral for treatment planning and prognosis. He illustrates these techniques in a case study of a non-healing wound. Finally, Dr. Patrone shares some technical tips for below-the-ankle interventions, including the benefits of ipsilateral antegrade access, sheath selection, and strategic contrast administration. --- TIMESTAMPS 00:00 - Introduction 02:25 - Multidisciplinary and Global Collaboration 05:59 - Explaining the Woundosome Concept 07:51 - Understanding Wound Perfusion 10:20 - Assessing the Effectiveness of Revascularization 20:09 - Case Example with Pictures 28:07 - Technical Tips for CLI Interventions --- RESOURCES Find Your Algorithm (FYA): https://fya-congress.com/ The "Woundosome" Concept and Its Impact on Procedural Outcomes in Patients With Chronic Limb-Threatening Ischemia: https://journals.sagepub.com/doi/10.1177/15266028241231745?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed Vascular imaging of the foot: the first step toward endovascular recanalization (Manzi): https://pubmed.ncbi.nlm.nih.gov/21997985/ BASIL-2 Trial: https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)00462-2/fulltext BackTable VI Ep. 90- Pedal Acceleration Time for Limb Salvage with Jill Sommerset and Dr. Mary Constantino: https://www.backtable.com/shows/vi/podcasts/90/pedal-acceleration-time-for-limb-salvage The First-in-Man "Si Se Puede" Study for the use of micro-oxygen sensors (Montero-Baker): https://pubmed.ncbi.nlm.nih.gov/26004327/ PEDRA Perfusion Monitoring: https://www.pedratech.com/ Armada XT Balloon: https://www.cardiovascular.abbott/us/en/hcp/products/peripheral-intervention/peripheral-dilatation-catheters/armada-14.html

In this episode of the BackTable Podcast, vascular surgeon Dr. Nicolas Mouawad and interventional radiologist Dr. Raja Ramaswamy share their insights on the changing landscape of deep vein thrombosis (DVT) management, steps of mechanical thrombectomy, and current research on DVT interventions. --- CHECK OUT OUR SPONSOR Inari Medical https://www.inarimedical.com/ --- SYNPOSIS The guests start by describing their typical referral patterns, noting that most cases come through the emergency department. In terms of workup, it is important to distinguish between acute and chronic DVTs and classify the thrombosis location as either proximal (femoral vein or higher) or distal. Anticoagulation, usually with direct oral anticoagulants, is always started, with efficacy largely determined by patient compliance. Regarding endovascular intervention, thrombolysis may be an effective adjunctive treatment if the clot occurred within a two-week timespan, but it carries a bleeding risk and requires ICU monitoring. On the other hand, mechanical thrombectomy is an option for both acute and chronic clots, allows for intervention in patients with high bleeding risk, and does not require post-procedural hospitalization. Both physicians emphasize that interventions should be employed if there are long-term benefits of avoiding post-thrombotic syndrome and pulmonary embolism. The physicians walk through a typical mechanical thrombectomy procedure, which involves the thrombectomy device, venogram, intravascular ultrasound, and possible stent placement. Finally, they discuss recent data, including the ATTRACT Trial for thrombolytics and the CLOUT Registry and Trial for ClotTriever use. Notably, they mention the DEFIANCE Trial as a current prospective randomized clinical trial for ClotTriever use in the iliofemoral region. --- TIMESTAMPS 00:00 - Introduction 03:48 - DVT Referral Patterns and Treatment Algorithms 08:55 - Choosing an Anticoagulation Regimen 11:01 - DVT Interventions 13:54 - Patient Scenarios and Treatment Decisions 22:29 - Post-Thrombotic Syndrome 26:16 - Mechanical Thrombectomy Technique 35:45 - Postoperative Care 39:09 - The Evolution of Mechanical Thrombectomy 43:38 - ATTRACT Trial 46:20 - CLOUT Trial --- RESOURCES Inari ClotTriever System: https://www.inarimedical.com/clottriever-system ATTRACT Trial: https://www.nejm.org/doi/full/10.1056/NEJMoa1615066 CLOUT Trial: https://pubmed.ncbi.nlm.nih.gov/35218955/ DEFIANCE Trial: https://evtoday.com/news/inari-medical-begins-defiance-randomized-clinical-trial-of-clottriever-system-in-dvt

In this episode, interventional cardiologist Dr. Peter Soukas joins us to discuss percutaneous transmural arterial bypass (PTAB) using the DETOUR system, a novel percutaneous treatment for extensive and complex blockages in the superficial femoral artery (SFA). --- CHECK OUT OUR SPONSOR Endologix https://endologix.com/ --- SYNPOSIS Dr. Soukas shares his extensive experience and insights into PTAB development, benefits, patient selection, and procedural details. The idea behind PTAB is to create an SFA-to-popliteal artery bypass through endovascular means, using a system of overlapping stent grafts within the femoral vein as a conduit. When planning the procedure, it is important to consider the location of reentry into the popliteal artery, avoid calcified zones, and meet femoral vein size criteria. Additionally, we explore the advantages of PTAB over other endovascular options and traditional open surgical bypass, which carry a higher likelihood of restenosis and longer recovery times, respectively. We also discuss the types of training and support available for physicians interested in adopting this technique, cost and reimbursement aspects, and the future direction of PTAB, including ongoing post-market studies. --- TIMESTAMPS 00:00 Introduction 02:38 Dr. Soukas’ Career in Vascular Medicine 05:19 Introduction to PTAB 13:00 Landing Zones 19:37 Stent Graft Sizing 23:14 Patient Selection and Adjunctive Medical Therapy 28:04 Procedural Risks 29:18 Navigating PTAB Implementation 32:20 Opportunities for Learning PTAB --- RESOURCES PTAB with the DETOUR System: https://endologix.com/ptab/detour/ Brown Vascular and Endovascular Fellowship: https://brownmedicine.org/3/cardiology-vascular-endovascular-fellowship/ COMPASS Trial: https://www.nejm.org/doi/full/10.1056/NEJMoa1709118 VOYAGER Trial: https://www.nejm.org/doi/full/10.1056/NEJMoa2000052 DETOUR 2 Trial: https://www.jvascsurg.org/article/S0741-5214(22)01274-5/fulltext
