Meta AnalysisBenefits of stereotactic radiosurgical anterior capsulotomy for obsessive-compulsive disorder: a meta-analysis.
Anterior capsulotomy (AC) is a therapeutic option for patients with severe, treatment-resistant obsessive-compulsive disorder (OCD). The procedure can be performed via multiple techniques, with stereotactic radiosurgery (SRS) gaining popularity because of its minimally invasive nature. The risk-benefit profile of AC performed specifically with SRS has not been well characterized. Therefore, the primary objective of this study was to characterize outcomes following stereotactic radiosurgical AC in OCD patients. ⋯ Stereotactic radiosurgical AC is an effective technique for treating OCD. Its efficacy is similar to that of AC performed via other lesioning techniques.

Multicenter StudyRisk factors for delayed postoperative hemorrhage in patients with brain arteriovenous malformations: an analysis of the nationwide multicenter prospective registry MATCH study.
Reducing the incidence of delayed postoperative hemorrhage (DPH) is one of the challenges in the surgical treatment of patients with brain arteriovenous malformations (bAVMs). This study aimed to identify several risk factors for DPH after bAVM resection and evaluate the impact of these risk factors in patients with bAVMs. ⋯ Patients with giant bAVMs or periventricular lesions are at higher risk for DPH after surgery. Strategies such as blood pressure control, preoperative embolization, intraoperative monitoring, and careful patient selection should be considered to reduce the risk of DPH in high-risk patients.

Multicenter StudyThe relevance of biologically effective dose for pain relief and sensory dysfunction after Gamma Knife radiosurgery for trigeminal neuralgia: an 871-patient multicenter study.
Recent studies have suggested that biologically effective dose (BED) is an important correlate of pain relief and sensory dysfunction after Gamma Knife radiosurgery (GKRS) for trigeminal neuralgia (TN). The goal of this study was to determine if BED is superior to prescription dose in predicting outcomes in TN patients undergoing GKRS as a first procedure. ⋯ BED and physical dose were both predictive of pain relief and could be used as treatment planning goals for distal and proximal targets, respectively, while considering maximum brainstem point dose < 29.5 Gy as a potential constraint for bothersome numbness.

Review Historical ArticleThe role of medical illustration in the evolution of transsphenoidal pituitary surgery.
Medical illustration played a crucial, yet often overlooked, role in the evolution of pituitary surgery. From the late 1800s to the present, many preeminent surgeons, in partnership with their surgical illustrator collaborators, developed and then shifted the paradigm of pituitary surgery, from an open procedure with high mortality and morbidity, to an endonasal approach with high success rates that is widely utilized today. This work aims to highlight the role of surgical illustrators as partners to their physician colleagues, creating artistically accessible road maps that shaped the development of the transsphenoidal approach.

Multicenter StudyThe natural history of aneurysms incompletely occluded by placement of a flow diverter: a multiinstitutional study.
Treatment of intracranial aneurysms by flow diversion is safe and effective and is increasingly popular. However, the correct treatment paradigm for aneurysms incompletely treated by initial placement of a flow diverter has not been established, nor have the subsequent natural history and occlusion rates of such aneurysms. The authors sought to outline the natural history of such aneurysms, which to date have been considered partially treated. ⋯ Aneurysms that have been incompletely treated by flow diversion have a benign natural history with progression toward occlusion over time, with or without retreatment.
