More about this episode

The physicians review the key indications for the procedure, highlighting evidence-based patient selection and emphasizing the need for interventional radiologists to critically assess the clinical workup rather than function merely as technicians. They discuss how a comprehensive pre-procedural workup relies on cross-sectional imaging to identify access obstacles and to plan for adequate filter placement in cases of variant anatomy. Dr. O’Neal also shares technical tips from the suite, including deployment mechanics, positioning considerations, and strategies for preventing common complications. The conversation concludes with the IR’s ongoing responsibility to ensure a robust, multidisciplinary follow-up system with referring specialties, outlining potential strategies to ensure these devices are safely retrieved in a timely manner when no longer indicated.

Can the right dosimetry approach turn palliative Y90 into a curative therapy? In this episode of the BackTable 2026 HCC Creator Weekend™, Interventional oncologists Dr. Riad Salem, Dr. Nima Kokabi, and Dr. Zach Berman examine modern Y90 dosimetry, from the decline of body-surface-area calculations to newer strategies that tailor treatment intensity to tumor burden, liver reserve, and clinical intent.

More about this episode

The doctors discuss how to choose how much radiation treatment to give and why “activity” (what you order) is different from “dose” (what tissue receives). The episode goes on to compare one-area calculations with more nuanced methods that distinguish tumor from healthy tissue, and explains why advanced 3D planning is often simpler after treatment than before. The discussion also covers treatment goals for various clinical scenarios, such as when to aim for complete ablation versus palliation, managing radiation lobectomy, and tailoring therapy in cases with portal vein tumor thrombus. The episode concludes with insights on how imaging informs treatment intensity and how local and systemic therapies work together in the latest Y90 approaches.

How do you build a pipeline for passionate, well-prepared interventional radiologists from day one of med school? In this episode of the BackTable Podcast, Dr. Aaron Rohr, interventional radiologist and associate professor at the University of Kansas, joins guest host Dr. Jessica Yoon to discuss how IR is accessed, taught, and experienced by medical students throughout their early education.

More about this episode

The physicians explore ways in which the transition from traditional fellowship models to integrated IR training pathways has increased the specialty’s visibility for early learners while also pointing out obstacles that continue to hinder greater integration of IR into the core medical curriculum. They discuss how IR’s involvement in diverse systems and disease processes offers valuable opportunities for comprehensive clinical learning, but simultaneously makes the specialty challenging for students with structured rotations to engage within a longitudinal fashion. Dr. Rohr goes on to highlight the Mid-America Vascular and Interventional Radiology Initiative Collegium (MAVIRIC), a student-led, faculty-supervised program hosted by KUMC that aims to introduce medical students to clinical, technical, and industry-related aspects of IR. He reflects on the effectiveness of hands-on interaction with devices and physicians’ demonstration of passion for their practice in piquing student interest. While acknowledging the burden of labor beyond work hours that such initiatives often demand of doctors and students alike, the physicians express their optimism for the growth of IR’s presence both in the hospital ecosystem and in the medical curriculum.

Pulmonary AVM may be rare, but missing them can lead to lifelong complications, especially in patients with hereditary hemorrhagic telangiectasia (HHT). How do you choose the right device and strategy to ensure long-term success with embolization? In this episode of the BackTable Podcast, host Dr. Kavi Krishnasamy is joined by Dr. Brian Funaki and Dr. Nima Kokabi to unpack the evolving treatment landscape for pulmonary arteriovenous malformations (PAVM). Through imaging breakdown, review of challenging real-world cases, and a discussion on advanced treatment strategies, the conversation tackles a key debate in pulmonary embolization: are plugs replacing coils as the new standard?

More about this episode

The discussion begins by defining HHT and PAVM, highlighting the risks associated with untreated PAVM and the critical need for genetic screening and multi-organ evaluation. Drs. Funaki and Kokabi review current treatment recommendations, surveillance imaging, and follow-up protocols, with special considerations for pediatric and high-risk patients. They explore practical tips for optimizing embolization performance, focusing on device selection and the evolving role of vascular plugs. By comparing different plug designs, such as wire count and pore size, and sharing lessons from challenging cases, including persistent lesions, tortuous anatomy, and pseudoaneurysm management, they provide advanced troubleshooting and decision-making strategies to achieve more durable, successful PAVM treatments.

More about this episode

The doctors explore why GJ tubes fail and how to manage common complications, such as balloon failures, vomiting-induced dislodgement, stoma enlargement, and recurrent malfunction due to poor gastrostomy angle or architecture, often seen with surgically placed G-tubes. Dr. Wong shares prevention strategies, including parent education on balloon-volume checks and refills, sending patients home with a backup G-tube, minimizing upsizing, and addressing traction and granulation tissue (including the use of silver nitrate). He also covers approaches to clog management such as warm water, Coke, aggressive flushing, and avoiding routing medications through the G port. The episode wraps up with a discussion on device preferences (AMT G-JET versus MIC-KEY), tips for wire and catheter exchanges, and the need for industry improvements in materials and lumen design.
