Ep. 334 New Balloon Technologies for CLI with Dr. Peter Soukas

Is microwave ablation only for simple liver tumors, or can it be a versatile ‘Swiss Army knife’ for a wide range of complex cases? In this episode, Dr. Driss Raissi of the University of Kentucky returns to BackTable to join host Dr. Chris Beck for a deep dive into advanced and unconventional microwave ablation techniques. They cover strategies for tackling a wide range of cases, from desmoid tumors to enterocutaneous fistulas.---This podcast is supported by:Medtronic Emprinthttps://www.medtronic.com/emprint---SYNPOSISDr. Raissi shares his ‘pre-burn’ technique that desiccates tissue and reduces complications like capsular burst and bleeding. He elaborates on his method for tackling large liver tumors with a single probe through overlapping ablations, needle placement techniques and his ‘lung seal technique’ to prevent pneumothorax. Dr. Raissi also shares how his previous experience in the ICU promotes close communication with anesthesiologists and how he ups his ablation game through collaboration, optimizing conditions for safe and effective ablation.The episode explores a series of unique, real-world applications beyond the usual scope of IRs. Dr. Raissi walks us through his novel approach to challenging cases, including cauterization of enterocutaneous fistulas, endometriomas and desmoid tumors.
