Chronic posthemorrhagic hydrocephalus often arises following spontaneous subarachnoid hemorrhage (SAH). Timely identification of patients predisposed to develop chronic shunt-dependent hydrocephalus may significantly enhance clinical outcomes. ⋯ Machine learning models, including logistic regression, demonstrate strong predictive capability for early chronic shunt-dependent hydrocephalus following spontaneous SAH, which may potentially contribute to more timely shunt placement interventions. This predictive capability is supported by our web interface, which simplifies the application of these models, aiding clinicians in efficiently determining the need for shunt placement.

To evaluate internal carotid artery's (ICA) anatomical relationships with atlantoaxial joints and posterior pharyngeal wall and to illustrate ICA injury risk during transoral procedures to upper cervical spine. ⋯ Transoral surgeries in the upper cervical spine carry potential ICA injury risk. They should be carefully deliberated in patients whose ICAs are in Zone 1. In cases of ICAs in Zone 2, meticulous subperiosteal stripping and gentle traction should be performed on the posterior pharyngeal wall. Preoperative identification of the course of ICAs is mandatory in patients undergoing transoral surgeries in the upper cervical spine.

Transarterial embolization (TAE) is generally the endovascular treatment of choice for tentorial dural arteriovenous fistula (dAVF). Although flow control of the feeder vessel has been reported to achieve complete shunt blockade, flow control in the absence of ischemia tolerance of ICA as a feeder has not been reported. we present a case in which treatment by Onyx TAE with intermittent flow control of the meningohypophyseal trunk (MHT) as the feeder was successful for a tentorial dAVF presenting with myelopathy without tolerance of ischemia. ⋯ Intermittent flow control of the MHT using a balloon may be safe and effective for cases showing no tolerance for ischemia.

We assessed the effectiveness of a treatment strategy based on hematoma characteristics and volume. ⋯ CSDH treatment strategies that consider to hematoma volume and characteristics have the potential to identify and reduce treatment rates in cases with high retreatment rates.

Addiction is a serious spiral where negative events or relationships triggers a craving even when the situation is caused by the addiction in the first place. Nucleus Accumbens (NAcc) is identified as an important hub for the neural pathways involved in the addictive behavior. Stimulation of this structure was demonstrated to be beneficial for addiction previously, but radioneuromodulation was never investigated until today. This study aimed to investigate if radioneuromodulation of the nucleus accumbens has any effect on alcohol addiction. ⋯ This study indicates that nucleus accumbens radioneuromodulation, although not significantly affecting baseline consumption, reduces intake when an aversive stimulus is involved, implying improved self-control.
