Ep. 315 Arterial Thrombectomy with Dr. Alexander Ushinsky

In this episode, host Dr. Chris Beck interviews Dr. Alexander Ushinsky about his standard workup and treatment when performing arterial thrombectomy in acute limb ischemia (ALI). --- CHECK OUT OUR SPONSOR AngioDynamics Auryon System https://www.auryon-system.com/ --- SHOW NOTES In the past three years, Dr. Ushinksy has focused on building up peripheral vasculature service lines at the Mallinckrodt Institute of Radiology at Washington University in St. Louis. He has acquired skills not only in treatment of ALI, but also in building referral bases and collaborating with vascular surgeons and cardiologists. To begin, we review important aspects of a focused history and physical exam. It is crucial to assess whether the patient has underlying peripheral arterial disease (PAD), other thromboembolic diseases, or underlying coagulopathies. Different etiologies of thrombus could require additional consultation with hematologists and cardiologists. Additionally, timing of symptom onset is important to consider when planning interventions in an on-call setting. Dr. Ushinsky relies on extremity pulse exams using bedside doppler and the Rutherford Classification System for ALI to ascertain whether intervention can be helpful. In cases of Rutherford class 1-2a, intervention is usually warranted. Cases that fall into class 2b may or may not require intervention, and cases in class 3 and beyond usually do not gain benefit from intervention since lower extremity paralysis and clot burden is so severe. With regards to types of interventions, Dr. Ushinsky highlights two common IR procedures– lysis catheter placement and endovascular thrombectomy. In the past, lysis catheters were the only available endovascular treatment. We walk through catheter placement, noting that in order to gain maximum benefit, the catheter should be placed across the entirety of the thrombus, with holes proximal and distal to the lesion, so that tPA can be infused throughout the clot and have appropriate inflow and outflow tracts. Good candidates for lysis catheter placement include patients who have extensive clot burden in small vessels and those who have underlying CLI that can be definitively addressed in a later procedure. A major difference between lytic catheter placement and thrombectomy is that patients receiving lytic therapy require admission to the ICU for close monitoring and frequent neurovascular checks. Next, we pivot to discussion about newer thrombectomy devices. Dr. Ushinsky describes pros and cons of common devices that are used in his practice and types of cases that would benefit from each one. Thrombectomy is useful if there is a low clot burden that can be addressed in a single session. Additionally, this procedure is more appropriate than lysis catheter placement if the patient is elderly, has had recent surgery, or is otherwise a poor candidate for systemic tPA. Dr. Ushinsky always performs a diagnostic angiogram at the beginning of the case and a completion angiogram to confirm that the lesion has been fully treated. Overall, he believes that the best intervention for a patient is the one that the practitioner feels the most adept at and can safely perform. --- RESOURCES Rutherford Acute Limb Ischemia Classification System: https://www.jvascsurg.org/article/S0741-5214(97)70045-4/fulltext#secd69653256e1488 Boston Scientific AngioJet Thrombectomy System: https://www.bostonscientific.com/en-US/products/thrombectomy-systems/angiojet-thrombectomy-system.html Penumbra Indigo Thrombectomy System: https://www.penumbrainc.com/peripheral-device/indigo-system/ AngioDynamics Auryon Thrombectomy System: https://www.angiodynamics.com/product/auryon/ Rotarex Excisional Atherectomy System: https://www.bd.com/en-us/products-and-solutions/products/product-families/rotarex-rotational-excisional-atherectomy-system Pounce Thrombectomy System: https://pouncesystem.com/ Find this episode on BackTable.com to see the full list of resources.

Ep. 475 Bariatric Embolization for Obesity Management with Dr Cliff Weiss

While GLP-1 agonists continue to gain popularity in the medical management of diabetes and obesity, Dr. Cliff Weiss is exploring bariatric arterial embolization (BAE) as an adjunctive therapy to help patients sustain weight loss. Dr. Weiss, the Director of IR Research at Johns Hopkins, joins the show to discuss the techniques and impacts of BAE for obesity treatment. --- CHECK OUT OUR SPONSOR Reflow Medical https://www.reflowmedical.com/ --- SYNPOSIS Dr. Weiss outlines his initial research interest in gastric embolization of the fundus to reduce ghrelin production. He began by studying the use of sclerosants for embolization but later shifted to using embolic spheres. BAE involves the targeted embolization of the left gastric artery, with or without the left gastroepiploic artery, using 300-500 micron embolic spheres. Dr. Weiss also employs a dilute mixture of spheres and a vasodilator to achieve distal arterial penetration. He describes the role of BAE in conjunction with existing surgical and pharmaceutical treatments. According to his experience, patients undergoing BAE achieve maximum weight loss 6-9 months after the procedure and can maintain this weight when they follow up in a weight management clinic. Additionally, Dr. Weiss reviews data from BAE studies, including the BEAT Obesity Trial and the recent BEATLES Trial. --- TIMESTAMPS 00:00 - Introduction 03:21 - Early Research and Development of BAE 07:39 - Potential Role of BAE in Obesity Treatment 16:03 - Procedure Details 25:28 - Post-Procedure Care and Patient Management 28:06 - Insights from the BEAT Obesity Trial 33:38 - BEATLES Trial 37:38 - Combination Therapy for Obesity --- RESOURCES BEAT Obesity Trial: https://pubs.rsna.org/doi/full/10.1148/radiol.2019182354 LC Bead/Bead Block: https://www.bostonscientific.com/en-US/products/embolization/lc-bead.html EmboSpheres: https://www.merit.com/product/embosphere-microspheres/ EMBIO Trial: https://bmjopen.bmj.com/content/13/9/e072327 BEATLES Trial: https://www.jvir.org/article/S1051-0443(23)01155-7/fulltext
