To define, from a series of surgically treated meningiomas of the posterior fossa with dural attachment above the dural sinuses, the best management of the sinus invasion according to the pattern of venous circulation. ⋯ In patients with posterior fossa meningiomas, we suggest to safety resect the involved sinus segment only when completely occluded. If the sinus lumen is not invaded or the tumor lies on the side of the unique or dominant transverse sinus, it should be preserved. This results in no or negligible risk of venous infarction and rather low recurrence rate.

Postoperative contact selection of deep brain stimulation (DBS), testing one contact at a time, is a clinically time-consuming procedure being challenged by incoming applications of more complex DBS leads. The objective of this study is to guide clinicians to select the optimal contact by neuroanatomic information derived from electrode reconstruction. ⋯ Electrode reconstruction could assist in selecting the clinical optimal contact and improving its efficiency.

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an established treatment for patients with Parkinson disease. One adverse event is the development of postoperative confusion. The aim of this study was to report the incidence and associated factors of postoperative confusion after STN DBS surgery. ⋯ The incidence of postoperative confusion in this cohort was 26.5%. After analysis of confounding factors, the Charlson comorbidity index was significantly associated with postoperative confusion.

To study improvements in outcomes after surgery for intracranial meningiomas. ⋯ Meningioma surgery as well as patient population changed over the 2 decades considered in this study. We observed higher rates of gross total resection in the later period and the perioperative outcomes improved or were unchanged, which signifies better long-term outcomes, RFS, and OS.

The term anterior communicating (ACom) aneurysm is often broadly used to classify any aneurysm formed on the A1-A2 junction, A1, A2, or ACom arteries. Aneurysm location has been associated with rupture risk, so whether an aneurysm is truly formed on the ACom artery can critically affect treatment decisions. The aim of this study was to reclassify broadly termed ACom aneurysms into 4 subgroups (A1, A2, true ACom, and A1-A2 junction) based on their location. ⋯ We found only 13% of the aneurysms initially referred to as ACom to be true ACom aneurysms. A more nuanced approach to ACom aneurysm classification may better guide management strategies.
