Multicenter StudySex-dependent characteristics and outcomes after clipping of unruptured intracranial aneurysms: a multicenter propensity score-matched study.
Disparities in the epidemiology and growth rates of aneurysms between the sexes are known. However, little is known about sex-dependent outcomes after microsurgical clipping of unruptured intracranial aneurysms (UIAs). The aim of this study was to examine sex differences in characteristics and outcomes after microsurgical clipping of UIAs and to perform a propensity score-matched analysis using an international multicenter cohort. ⋯ Despite overall differences between male and female patients in demographics, comorbidities, and treated aneurysm location, sex did not relevantly affect surgical performance or perioperative complication rates.

Multicenter StudyStratified assessment of treatment approach for craniocervical junction arteriovenous fistulas: a multicenter cohort study and literature review.
Craniocervical junction arteriovenous fistulas (CCJ-AVFs) are complex vascular shunts that present a challenge for treatment. The aim of this study was to compare the clinical outcomes of microsurgery and endovascular embolization for CCJ-AVFs and to determine whether the treatment approach affected the obliteration rate and neurological improvement. ⋯ This study supports microsurgery as the best treatment modality for CCJ-AVFs, exhibiting the highest rates of complete obliteration. Conversely, embolization via the VA can result in a lower occlusion rate and less neurological improvement. In CCJ-AVFs with CA feeders, embolization via the CA can be a safe and effective alternative to microsurgery.

Multicenter StudyStereotactic radiosurgery for brain metastasis from cholangiocarcinoma.
Accounting for approximately 15% of primary liver cancers and 3% of gastrointestinal malignancies, cholangiocarcinoma (CCA) poses a serious health concern given its high mortality rate. Managing brain metastases (BMs) from CCA is challenging because of their rarity and poor prognosis, with little guidance on treatment from the literature. In this study, the authors aimed to evaluate the safety and efficacy of stereotactic radiosurgery (SRS) in managing BMs from CCA. ⋯ SRS is an effective option for managing BMs in CCA patients, showing promise in LC and a high safety profile.

Multicenter StudyASCOD phenotyping of acute vertebrobasilar artery occlusion treated by mechanical thrombectomy: insight from the PERSIST registry.
Determining the underlying etiology of acute vertebrobasilar artery occlusion (VBAO) is crucial for selecting an appropriate treatment approach. The authors aimed to investigate the distribution of etiology and the association with functional outcomes in patients with acute VBAO who underwent endovascular treatment in which atherosclerosis, small-vessel disease, cardiac pathology, other causes, and dissection (ASCOD) phenotyping was used. ⋯ The most common etiology in patients with VBAO was atherosclerosis, followed by cardiac pathology and other. Compared to the A1 subgroup, the C1 subgroup showed better functional outcomes, whereas the O1 subgroup showed worse outcomes. Additionally, there was no statistically significant difference in the recurrence risk.

Multicenter Study Comparative Study Observational StudyEarly versus delayed cranioplasty after decompressive craniectomy in traumatic brain injury: a multicenter observational study within CENTER-TBI and Net-QuRe.
The aim of this study was to compare the outcomes of early (≤ 90 days) and delayed (> 90 days) cranioplasty following decompressive craniectomy (DC) in patients with traumatic brain injury (TBI). ⋯ Functional outcome and quality of life were similar between early and delayed cranioplasty in patients who had undergone DC for TBI. Neurosurgeons may consider performing cranioplasty during the index admission (early) to simplify the patient's chain of care and prevent readmission for cranioplasty but should be vigilant for an increased possibility of hydrocephalus. Clinical trial registration nos.: CENTER-TBI, NCT02210221 (clinicaltrials.gov); Net-QuRe, NTR6003 (trialsearch.who.int) and NL5761 (onderzoekmetmensen.nl).
