Ep. 343 Microwave Ablation: A Powerful but Underused Modality for Treatment of Spine Tumors with Dr. Majid Khan

In this episode, Dr. Jacob Fleming interviews Dr. Majid Khan, a spine interventionalist and expert in neuroimaging, about microwave ablation, a new treatment modality that has garnered significant attention. --- CHECK OUT OUR SPONSOR Boston Scientific Lab Agent https://www.bostonscientific.com/en-US/customer-service/ordering/lab-agent/contact.html?utm_source=oth_site&utm_medium=native&utm_campaign=pi-at-us-labagent-hci&utm_content=n-backtable-n-backtable_site_labagent_1_2023&cid=n10013205 --- EARN CME Reflect on how this Podcast applies to your day-to-day and earn free AMA PRA Category 1 CMEs: https://earnc.me/1YOW1H --- SHOW NOTES Dr. Khan completed his radiology residency in New York and his fellowship in neuroradiology at John Hopkins. As he progressed in the field, he observed a significant shift in spinal care towards interventional methods and began to study these techniques, which included radiofrequency ablation (RFA) and cryoablation for treating spinal tumors. However, when he treated cases of prostate cancer spine metastases, he realized that RFA was challenging, due to the high bone impedance of osteoblastic lesions. This obstacle piqued his interest in microwave ablation, an alternative technique that employs an electromagnetic wave to induce rapid oscillation of hydrogen atoms in water molecules. This oscillation generates frictional heat, leading to coagulative tumor necrosis. Unlike RFA, microwave ablation significantly reduces bone impedance, making it a promising solution for these cases. Dr. Khan cautions that special care must be taken when operating in areas near nerves due to the elevated temperatures. To ensure safety, he recommends the use of a probe within the frequency range of 900 MHz to 1.2 GHz and the incorporation of thermocouplers as a safeguard during the ablation process. Furthermore, Dr. Khan delves into the indications for ablation based on the extent of tumor metastasis. In cases of oligometastatic disease, he advises a more aggressive treatment approach by extending the ablation zone beyond the actual tumor size. On the other hand, when dealing with diffusely metastatic disease, the primary goal of treatment shifts towards pain reduction. The two conclude their discussion with Dr. Khan’s advice for physicians planning to utilize microwave ablation. He advises them to approach their initial 5-10 cases judiciously, in an effort to minimize the risk of complications that may adversely impact their self-confidence. Having adequate self confidence enhances the likelihood of achieving successful outcomes. For those looking for a valuable resource in the field, Dr. Khan has recently published a comprehensive textbook that features contributions from experts in the field. --- RESOURCES “Assessing long-term locoregional control of spinal osseous metastases after microwave ablation”: https://pubmed.ncbi.nlm.nih.gov/35963064/ Vertebral Augmentation: https://shop.thieme.com/Vertebral-Augmentation/9781684200153 Image Guided Interventions of the Spine https://link.springer.com/book/10.1007/978-3-030-80079-6

Reflect on how this Podcast applies to your day-to-day and earn AMA PRA Category 1 CMEs here: https://earnc.me/xQPc7h In this episode, Dr. Ashley Agan and Dr. Sabeen Dhand join Dr. Gopi Shah to discuss IR and ENT treatment of epistaxis. We cover the differences in how epistaxis presents for ENT and IR as well as how epistaxis presents in children and older patients. Dr. Agan tells us about the types of nosebleeds that are common and the general treatment algorithm she follows. We discuss nasal packing and decongestant sprays for treatment and how to know when to take the patient to the OR. Dr. Agan talks about isolating the bleeding spot, how to use a foley for posterior nosebleeds, and SPA litigation. We discuss why ENT might consult IR for an embolization. Dr. Dhand tells us about the contraindications for embolization and the procedure for treating the epistaxis. We review the materials that should be used and why it is important to look out for artery connections and pseudoaneurysms. We discuss the pearls and pitfalls of ENT and IR treatment of epistaxis and how to avoid the risk of stroke.
