To evaluate the feasibility of sodium fluorescein (Na-Fl)-guided surgery involving the use of the PENTERO 900 surgical microscope equipped with the YELLOW-560 nm filter and low-dose Na-FL (200 mg/2-4 mg/kg) in meningioma surgery. ⋯ Na-Fl guidance with the use of the YELLOW-560 filter is safe and effective during meningioma surgery.

Evaluating preoperative frailty is critical for guiding shared surgical decision-making. The purpose of this study was to develop a novel preoperative frailty index for classification of adverse outcomes following cranial neurosurgery procedures. ⋯ Neurosurgical patients undergo extensive preoperative evaluation, but the field currently lacks a robust bedside scoring system for quantifying patient frailty. In this study, we introduced a novel preoperative frailty index capable of classifying 30-day morbidity and mortality outcomes following cranial neurosurgeries.

Thalamic deep brain stimulation (DBS) is an effective strategy for treatment of essential tremor (ET). With limitations of imaging modalities, targeting largely relies on indirect methods. This study was designed to determine the optimal target for DBS in ET and construct a targeting method based on probabilistic maps. ⋯ The FX method may be an additional targeting strategy in patients undergoing thalamic DBS surgery.

Subcallosal artery (ScA) infarction is a well-recognized but uncommon complication of surgical treatment of anterior communicating artery aneurysms. ⋯ Our case demonstrates a rare case of isolated ScA infarction induced by a local vasospasm and highlights the importance of its recognition. An early identification and intervention could potentially halt irreparable cerebral injury.

In the context of bronchial cancers, the brain is one of the most frequent sites for metastases. Local treatments of these metastases have evolved and are often combined to obtain greater efficiency, while the main objective remains to reduce the symptoms. Radiosurgery is currently used as a primary option for patients harboring few numbers of small to middle-sized brain metastases. In nonsquamous non-small cell lung cancer (NSCLC), chemotherapy is often associated with bevacizumab. Our goal was to assess the safety of this early combination. ⋯ Radiosurgery may be safely combined with bevacizumab quite early on for patients with nonsquamous NSCLC with brain metastases.
