Focused ultrasound in neurosurgery: a historical perspective

Maya Harary, David J. Segar, Kevin T. Huang, Ian J. Tafel, Pablo A. Valdes, and G. Rees Cosgrove

57% pain relief at the 3-month and 1-year follow-up, respectively. 34 Trigeminal neuralgia had originally been avoided due to concerns about heating of surrounding sensitive structures. However, in 2013, a cadaveric study demonstrated that with the implementation of “no-pass” regions of the skull base, the trigeminal ganglion could be lesioned without significantly elevating the temperature of surrounding structures. 55 Epilepsy The application of MRgFUS to the treatment of epilepsy has taken 2 approaches: the suppression of epileptic activity and the lesioning of

Cost-effectiveness development for the postoperative care of craniotomy patients: a safe transitions pathway in neurological surgery

Joseph A. Osorio, Michael M. Safaee, Jennifer Viner, Sujatha Sankaran, Sarah Imershein, Ezekiel Adigun, Gabriela Weigel, Mitchel S. Berger, and Michael W. McDermott

decompressions, microvascular decompressions for trigeminal neuralgia, and surgery for infratentorial tumors and other types of supratentorial tumors. These patients were similarly identified, as our initial population, by looking at trends for postoperative ICU stay and having similar indications for the ICU needs (frequent monitoring). Table 2 shows the STP and expanded diagnoses/procedures that would later be added into the pathway. Table 3 demonstrates cost-reduction estimates based on the mean number of patients included in the STP driven by our retrospective

High-intensity focused ultrasound: past, present, and future in neurosurgery

Syed A. Quadri, Muhammad Waqas, Inamullah Khan, Muhammad Adnan Khan, Sajid S. Suriya, Mudassir Farooqui, and Brian Fiani

there is a rise in CD3+ and CD4+ subsets and the CD4+/CD8+ ratio in the blood due to the activation of dendritic cells. 40 , 87 HIFU might be an attractive option in situations in which a host’s antitumor immunity needs to be enhanced. A HIFU-induced strong antitumor immune response could help to combat residual tumor cells at the primary lesion site and suppress metastasis. 40 , 87 Future Applications of tcMRgFUS Trigeminal Neuralgia A recent cadaveric model study with real-time MR thermometry and experimentation with thermocouples in a transcranial in vitro setup
