Ep. 596 Thrombin Injection for Pseudoaneurysms: Technique & Considerations with Dr. Gabriel Werder

Pseudoaneurysms are among the most common complications of vascular access. Here’s a refresher on how to treat them with thrombin injection featuring interventional radiologist Dr. Gabriel Werder from Radiology Associates of Florida. Alongside host Dr. Chris Beck, Dr. Werder outlines both the clinical and procedural approach to thrombin injection for pseudoaneurysms. --- SYNPOSIS This episode covers best practices for thrombin injection procedures, including preferred needle positioning techniques, sedation protocols, ultrasound evaluation, and follow-up care. The physicians discuss recent evidence supporting needle placement at the center of the sac from an inferior approach, and share specific cases that highlight the utility of balloon-assisted thrombin injections. Dr. Werder provides a detailed walkthrough of his technique, including contralateral femoral access, balloon oversizing, and preferences for a post-procedural run-off angiogram. The episode also touches on complex pseudoaneurysms with multiple sacs and learnings from several other unique cases. --- TIMESTAMPS 00:00 - Introduction03:53 - Thrombin Injection Procedural Overview08:14 - Procedure Setup and Execution16:13 - Needle Positioning and Ultrasound Evaluation18:47 - Handling Complex Pseudoaneurysms19:20 - Balloon Occlusion Thrombin Injection19:59 - Case Studies and Practical Insights26:21 - Post-Procedure Care and Follow-Up29:17 - Final Thoughts and Reflections --- RESOURCES Kim et al. “Optimal thrombin injection method for the treatment of femoral artery pseudoaneurysm” - https://www.jthjournal.org/article/S1538-7836(24)00048-5/fulltext
