Procedural outcomes of the transradial versus transfemoral approach for diagnostic cerebral angiograms according to BMI: a propensity score-matched analysis.
BMI has been shown to affect choice of access site in coronary intervention procedures, with lower complications reported during transradial (TR) access. To the authors' knowledge, the effect of BMI on outcomes in patients undergoing diagnostic cerebral angiography remains undescribed. This study compares outcomes for BMI subgroups based on access site (TR vs transfemoral [TF] access). ⋯ TR access in diagnostic cerebral angiography is associated with shorter procedure times and no increased risk of complications compared to TF access across all BMI subgroups. Obese patients experienced shorter LOS with TR access. This study adds to the literature on the safety and efficacy of TR access across all BMI subgroups. Further studies are necessary to validate these preliminary results.

Predictors of trigeminal neuropathy in patients receiving Gamma Knife stereotactic radiosurgery for vestibular schwannoma.
The authors' objective was to validate dosimetric and clinical predictors of the development of trigeminal neuropathy (Tn) in patients treated with stereotactic radiosurgery (SRS) for a diagnosis of vestibular schwannoma (VS). ⋯ The only significant factor in the risk of development of Tn after SRS for VS was the volume of CN V that received ≥ 11 Gy. This should be routinely incorporated into dosimetric planning constraints and patients should be counseled about the risk of adverse effects if it cannot be met. For those with growing VS and a gap to the trigeminal nerve, it may be prudent to provide earlier treatment with SRS to enable application of this dosimetric constraint and reduced risk of Tn.

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 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.
