BackTable Vascular & Interventional

How do you differentiate between iliac vein compression, gonadal vein reflux, and Nutcracker syndrome in patients with chronic pelvic pain? Dr. Deepak Sudheendra, director and interventional radiologist at 360 Vascular Institute, joins host Dr. Ally Baheti to share his approach to evaluating and managing pelvic venous disease (PVD). --- Get the BackTable app https://www.backtable.com/app --- Timestamps 00:00 - Introduction01:43 - PVD Demand at Penn06:42 - Approach & Algorithm12:08 - Variation in Iliac Vein Compression15:58 - Treatment Approaches19:20 - Important Ultrasounds22:15 - Intra-Procedural Workflow31:14 - Iliac Vein Stenting and Avoiding Complications36:31 - Gonadal Vein Embolization and Working with Patients42:20 - Iliac Vein Embolization and Post-Op Care --- More about this episode Dr. Sudheendra's clinical algorithm for diagnosing PVD emphasizes the importance of patient history and specific symptoms over isolated cross-sectional imaging findings. He shares his approach to the pre-procedural workup, highlighting the necessity of a standing venous reflux ultrasound to rule out superficial venous insufficiency. Beyond the technical steps, Dr. Sudheendra emphasizes the "soft skills" of managing a venous practice: counseling patients on conservative treatments like pelvic floor therapy, explicitly setting expectations about postoperative back pain, and avoiding unnecessary bilateral stents in young women. Dr. Sudheendra details his intra-procedural workflow for diagnosing and treating PVD, providing a look into his unique preference for right internal jugular (IJ) vein access to perform venograms and place iliac vein stents. He explains how this approach allows him to consistently check inflow from the lower extremities, and shares his techniques for performing gonadal vein embolizations and accurately sizing iliac vein stents to prevent lifelong complications. --- BackTable Vascular & Interventional (VI) is the go-to podcast for interventional radiologists, vascular surgeons, and interventional cardiologists.

As interventional radiology cements its position as a primary clinical responder for acute arterial hemorrhage, what if you could achieve rapid and durable arterial occlusion with a single, highly deliverable device? In this episode of the BackTable Podcast, Dr. Alex Villalobos (UNC), Dr. Nima Kokabi (UNC), and Dr. Brian Funaki (UChicago) join host Dr. Kavi Krishnasamy to explore the shifting paradigms of arterial embolization in a case-based discussion highlighting modern vascular plug technologies.--- Get the BackTable app https://www.backtable.com/app --- This podcast is supported by Okami Medicalhttps://okamimedical.com/ --- Timestamps 00:00 - Introduction01:24 - Trauma Activation Workflow06:42 - Empiric Arterial Embolization Indications10:40 - Embolic Agent Preferences and Value Analysis17:18 - Embolics on the Shelf19:32 - LOBO Plug Use Cases20:58 - Case 1: Abdominal Wall Hematoma23:54 - LOBO Advantages, Cost, and Microcatheter Compatibility26:33 - Alternative Access Approaches30:31 - LOBO Sizing and Trackability35:26 - Pusher Wire Features38:20 - Delivery Catheter Requirements43:41 - Case 2: Retroperitoneal Bleed45:15 - LOBO Deployment Technique49:41 - Case 3: Splenic Trauma53:51 - Occlusion Time and Adjunct Embolics57:07 - Closing Remarks --- More about this episode The panel begins by discussing the range of embolic options and combinations at their disposal, sharing their preferences and treatment algorithms in various clinical scenarios. In particular, they emphasize the need for tools that provide immediate, predictable occlusion without the technical burden and cost of needing to deploy multiple embolic agents. The physicians go on to focus on Okami Medical’s LOBO vascular plug as a primary solution for rapid vessel occlusion, highlighting the micro-pore architecture and unique deliverability through microcatheters that make it advantageous for precise positioning and reliable embolization. Exploring its use in cases including rectus sheath hematomas, retroperitoneal bleeding, and splenic trauma, the physicians detail the technical nuances of sizing and positioning the LOBO as well as the long-term advantages of its artifact-free design. This episode ultimately underscores a growing preference for streamlined arterial embolization workflows that prioritize rapid stasis and clinical predictability while leveraging the strengths of a multimodal embolic toolkit.

Patients and IRs alike dread the persistent cycles of malfunction and repeated procedures that often accompany biliary drains. What can you do to keep patients off the doorstep of reintervention? In this episode of the BackTable Podcast, Dr. Ahsun Riaz of Northwestern Medicine joins host Dr. Michael Barraza to walk through strategies for preventing and managing complications of percutaneous biliary drain placement. --- Get the BackTable app https://www.backtable.com/app --- Timestamps 00:00 - Introduction01:51 - Complication Rates and Associated Factors06:09 - PTC in Non-Dilated Biliary Systems11:00 - Techniques for Access and Drain Placement15:10 - Drain Flushing, Capping, and Ideal Positioning17:48 - External versus Internal-External Biliary Drains20:42 - Managing Pericatheter Leakage23:01 - Life Expectancy and Stenting Malignant Strictures26:32 - Tract Maturation and Minimizing Access Sites28:56 - Addressing Unresolving Hyperbilirubinemia34:52 - Managing Bloody Drain Output38:12 - Approach to Dislodged Drains39:40 - Drain-Associated Pain and Exchange Timing42:49 - Strategy for Benign Biliary Strictures45:18 - Final Thoughts and Closing Remarks --- More about this episode The discussion begins with a look at the data on biliary drain-related adverse events, emphasizing the need to bring down the high rates of complications that may take a toll on patients' quality of life. Dr. Riaz stresses the importance of employing techniques at initial drain placement, such as placing left-sided drains where appropriate and minimizing biliary pressure buildup, to reduce the starting risk of malfunction. The physicians go on to share their algorithms for approaching various scenarios, from pericatheter leakage and drain dislodgement to unresolving hyperbilirubinemia, pointing out the factors and observations that should influence treatment approaches during planning and intraprocedurally. Finally, the physicians address the evolving landscape of long-term biliary management, assessing potential drainage strategies as survival rates improve in hepatobiliary malignancies, and underscore the critical importance of collaboration with gastroenterologists and surgeons to ensure cohesive, goals-of-care-centered management. --- Resources Adverse Events After Percutaneous Transhepatic Biliary Drainage: A 10-Year Retrospective Analysishttps://doi.org/10.1016/j.jvir.2024.12.022
