The 2022 Annual Scientific Meeting of the American Association of Neurological Surgeons (AANS) was held in Philadelphia April 29—May 2. It was the first in-person AANS annual meeting since 2019. As the largest gathering of neurosurgeons in the nation, the meeting features the field’s latest research and technological advances. It is attended by neurosurgeons, neurosurgical residents, medical students, neuroscience nurses, clinical specialists, physician assistants, allied health professionals, and other medical professionals.

“There was a lot of engagement and excitement in the neurosurgical community toward transcranial focused ultrasound. The presentations were informative and reached a large audience,” said Vibhor Krishna, MD, Associate Professor of Neurosurgery at the University of North Carolina, Chapel Hill, a focused ultrasound expert who conducts translational neuroimaging research to optimize the technique of focused ultrasound and improve patient outcomes. “Several mechanisms (ablation, blood-brain barrier opening) and various applications of the technology were discussed, including movement disorders, neuropathic pain, and epilepsy.”

The seven sessions that included focused ultrasound topics are listed below.
