Ep. 376 New Frontiers in Spinal Tumor Ablation and Augmentation with Dr. Dana Dunleavy

In this episode, host Dr. Jacob Fleming interviews Dr. Dana Dunleavy about spinal tumor ablation and vertebral augmentation. Dana is an interventional radiologist and Director of Windsong Interventional & Vascular Services. --- CHECK OUT OUR SPONSOR Stryker Interventional Spine https://www.strykerivs.com --- SHOW NOTES Dana begins the discussion by reflecting on his upbringing in a small country town. His parents, his mother a midwife and his father a contractor, shaped his early experiences. His exposure to medicine began through his mother, particularly in witnessing childbirths. As he navigated his way through medical school, he contemplated various specialties, including orthopedic surgery, interventional radiology, and neurosurgery. He discovered incredible mentors in radiology and ultimately found his place in the field of interventional radiology. During his residency at Johns Hopkins, he sought externships in interventional spine and had the opportunity to immerse himself in this field for one month. He underscores the significance of participating in tumor boards and being a valuable contributor to the team in terms of diagnosis and treatment. He also emphasizes the value of calling consults when performing biopsies and the importance of meeting with the patient face-to-face and engaging in a thorough discussion of the treatment plan. Next, Dana delves deeper into the topics of bone tumor ablation and mechanical augmentation. He notes the importance of having a comprehensive understanding of the patient's anatomy and being well-versed in interventional tools. Cement extravasation is a feared complication of vertebral augmentation, so Dana discusses the role of implants as a means to establish structural support and mitigate the risk of cement leakage. In addition, he talks about his approach in combining ablation with mechanical augmentation so that the augmentation provides a structure after the ablation. Lastly, he discusses the use of advanced technology such as cone beam CT in trajectory planning. He shares his hybrid approach to performing bone biopsies, utilizing fluoroscopy during access and cone beam CT to ascertain accurate trajectory.
