Link between both infratentorial and supratentorial intracranial pressure burdens and final outcome in patients with infratentorial brain injury.
Increased intracranial pressure (ICP) is most likely not being transmitted uniformly within the cranium. The ICP profiles in the supra- and infratentorial compartments remain largely unclear. Increased ICP in the cerebellum, however, is insufficiently captured by supratentorial ICP (ICPsup) monitoring due to compartmentalization through the tentorium. The authors hypothesized that additional infratentorial ICP (ICPinf) monitoring can be clinically valuable in selected patients. The aims of this study were to demonstrate the safety and feasibility of ICPinf monitoring and to investigate the influence of the ICPinf on clinical outcome in a real-world setting. ⋯ Supplementary ICPinf monitoring is safe and reliable. There is a significant transtentorial pressure gradient within the cranium showing elevated ICPs in the PF. Elevated ICP levels in the PF were strongly associated with unfavorable neurological outcome irrespective of ICPsup values.

Multicenter StudySafety of discontinuing antiplatelet therapy 12-24 months after stent-assisted coil embolization: a multicenter retrospective study.
Antiplatelet medication is required after stent-assisted coil embolization (SACE) to avoid thromboembolic complications. Currently, there is no consensus on how long the antiplatelet agent should be maintained. The authors investigated clinical outcomes in patients who discontinued their antiplatelet agent 12-24 months after SACE. ⋯ These results suggest that it may be safe to discontinue antiplatelet medication after SACE in patients at low risk for ischemia, and that it appears safe to discontinue the agent at approximately 15 months after the procedure. Large cohort-based prospective studies or randomized clinical trials are warranted to confirm these results.

A long-term study of posterior circulation changes after revascularization in patients with moyamoya disease.
This study aimed to explore the long-term course of posterior circulation changes and predictors in patients with moyamoya disease (MMD). ⋯ Progression of PCA stenosis is common in patients with MMD, even if the PCA is normal initially. Mutations of RNF213 p.R4810K may predict PCA involvement or progression. Follow-up of the PCA in MMD patients should be conducted, and timely surgical revascularization is needed.

ReviewFlow diversion: a disruptive technology coming of age. Lessons learned and challenges for the future.
Intracranial aneurysm treatment has been revolutionized over the last decade with the development of flow diversion technology. The use of this technology has evolved rapidly and has proven that cerebrovascular disease treatment remains one of the forefront innovation areas in neurosurgery. ⋯ Further advances and innovations of flow-diverting devices are underway and intended to improve the safety and efficacy of this therapy. This review article provides a detailed discussion about the origin, mechanism of action, initial experience, complications, types of devices, and future perspectives of flow diversion technology.

Multicenter Study Observational StudyIncidence and risk factors of posttraumatic hydrocephalus and its association with outcome following intensive care unit treatment for traumatic brain injury: a multicenter observational study.
Posttraumatic hydrocephalus (PTH) is a recognized long-term complication of traumatic brain injury (TBI). The authors assessed the incidence and risk factors of PTH and its association with outcome in patients with TBI who were treated in the intensive care unit (ICU). ⋯ PTH is an uncommon long-term complication of TBI, with several risk factors that are identifiable early during neurointensive care. The development of PTH is independently associated with poor functional outcome. Whether earlier detection and treatment of PTH leads to improved outcomes remains unknown, highlighting the importance of adequate follow-up and prompt detection and treatment of the condition.
