The 2022 Annual Meeting of the Congress of Neurological Surgeons (CNS), “Neurosurgery Connected,” was held October 8–12, 2022, in San Francisco.
In one of the Saturday symposia, “Controversies in Movement Disorder Surgery,” Experts debated hot topics within the movement disorder community, including: What is the optimal technique: Deep Brain Stimulation (DBS) vs. High Intensity Focused Ultrasound (HIFU)? The session included case presentations and discussion of complication avoidance or management. Course directors were Sharona Ben-Haim and André Machado, and faculty included Kara Beasley, Casey H. Halpern, Erika A. Petersen, Francisco A. Ponce, Tejas Sankar, and Jason M. Schwalb.
A session titled, “Intraprocedural Delivery of Adjuvant Treatments for Brain and Spine Tumors,” included microbubbles plus focused ultrasound. Its description stated, “Tumor surgeons are becoming increasingly involved with delivery of adjuvant treatment during their procedures.” The session highlighted recent advances in intraoperative radiation therapy, microbubble ultrasound, and laser interstitial thermal therapy (LITT) for spinal tumors. The session was moderated by Nancy A. Oberheim Bush and Tiffany R. Hodges. Faculty included Isabelle Germano (intraoperative radiation therapy), Christopher Cifarelli (microbubble ultrasound), Francesco DiMeco (LITT), and Claudio Tatsui (oral abstract presentations).
Five abstracts that may be of interest to the focused ultrasound community are listed below. The full text for these abstracts can be accessed by by downloading the CNS app (search “Congress of Neurological Surgeons” and look for the “Neurosurgery Connected” tagline).
