Ep. 383 Reflections on a Career in Clinical IR with Dr. Alan Matsumoto

Before the advent of TIPS, mesocaval shunts were considered a less popular option for managing portal hypertension. But today, could they serve as a lifeline when no other choices remain? This week on BackTable, Drs. Omar Chohan and Harris Chengazi (Great Lakes Medical Imaging) join host Dr. Chris Beck to discuss the evolving role of endovascular mesocaval shunts, covering patient selection, clinical decision-making, and technical pearls. --- SYNPOSIS In this episode, the hosts delve into the specialized procedure of meso-caval shunts, focusing on its applications for patients with portal hypertension who have no other viable options. This discussion includes detailed case studies, such as one involving a woman with autoimmune hepatitis and another with pancreatic cancer, showcasing the practical challenges and innovative solutions in creating these shunts. In each case, they detail the rationale for patient selection, difficult anatomy, procedural steps, and resolution of symptoms like recurrent ascites and variceal bleeding. The episode emphasizes the importance of pre-procedure planning, collaboration, and precise imaging, utilizing advanced tools like the 4D CT scanner. The conversation also highlights the compassionate motivation behind these complex procedures, aimed at improving patients' quality of life. --- TIMESTAMPS 00:00 - Introduction 03:07 - Historical Context and Indications06:49 - Case 1: Patient with Refractory Ascites34:00 - Case 2: Recurrent GI Bleeding41:16 - Case 3: TIPS Consult - Pancreatic Cancer and Duodenal Varices47:44 - Lessons, Pearls, and Tips56:13 - Final Thoughts --- RESOURCES A Case Series of Dr. Chengazi's Mesocaval Shunts on X:https://x.com/chengazimd/status/1966337167879438571 Episode 573 Portal Hypertension Treatment Strategies:https://www.backtable.com/shows/vi/podcasts/473/portal-hypertension-treatment-strategies-ir-hepatology-perspectives TIPS University Freshman Year:https://www.backtable.com/shows/vi/podcasts/123/tips-university-freshman-year-referrals-pre-op-workup TIPS University Sophomore Year:https://www.backtable.com/shows/vi/podcasts/124/tips-university-sophomore-year-basic-procedure-technique TIPS University Junior Year:https://www.backtable.com/shows/vi/podcasts/125/tips-university-junior-year-advanced-techniques-ice-splenic-access TIPS University Senior Year:https://www.backtable.com/shows/vi/podcasts/126/tips-university-senior-year-gunsight-technique-splenic-closure

Below the knee atherectomy is a hot topic right now in the vascular community. Why is it so controversial? Dr. Anahita Dua, vascular surgeon at Mass General, joins host Dr. Sabeen Dhand to explore the utility of this technique and the pressing need for more Level I evidence in this space. --- This podcast is supported by:AngioDynamicshttps://www.auryon-system.com/ --- SYNPOSIS The conversation dives into the controversial role of below-the-knee atherectomy in limb salvage, an area where data has long been debated. Dr. Dua, principal investigator of the AMBITION BTK Trial—the first randomized controlled trial comparing below-the-knee atherectomy to angioplasty alone—introduces the trial and explains how it fits into the current body of literature. Together, the doctors review past evidence, current practice, and the future outlook for tibial interventions. Dr. Dua outlines the wide range of techniques and clinical strategies used to manage PAD, and stresses the importance of physician engagement with the NIH and research community to establish stronger, evidence-based protocols. She also shares her candid thoughts on the most overrated and underrated devices in tibial intervention, highlighting atherectomy’s potential role in vessel preparation before below-the-knee treatment. --- TIMESTAMPS 00:00 - Introduction04:55 - Current State of Evidence and Challenges10:54 - Heterogeneity in PAD Treatment14:26 - Need for National Metrics and Standardization20:51 - AMBITION BTK Trial and Importance27:23 - Potential Outcomes and Implications30:18 - Trial Design34:56 - Advice for Practitioners37:36 - Underrated and Overrated Devices41:50 - Conclusion --- RESOURCES AMBITION BTK Trial:https://www.angiodynamics.com/studies/ambition-btk/
