Clinical presentation, hemorrhage risk, and outcome in patients with familial cavernous malformations: a pragmatic prospective analysis of 75 patients.
Newly diagnosed patients with a familial cavernous malformation (FCM) and their families are concerned about their future outlook, which is scarcely discussed in the literature. The authors studied a prospective contemporary cohort of patients with FCMs to assess demographics, mode of presentation, prospective risk of hemorrhage and seizures, need for surgery, and functional outcome over an extended interval. ⋯ The authors' findings provide clinically useful information on hemorrhage rate, seizure rate, the likelihood of surgery, and functional outcome. These findings can be helpful to practicing physicians when counseling patients with FCM and their families, who are often apprehensive about their future and well-being.

Observational StudyInterrupted intraarterial selective cooling infusion combined with mechanical thrombectomy in patients with acute ischemic stroke: a prospective, nonrandomized observational cohort study.
The authors aimed to explore the feasibility and efficiency of an interrupted intraarterial selective cooling infusion (IA-SCI) combined with mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS). ⋯ Interrupted IA-SCI for patients with intracranial large vessel occlusion AIS symptoms treated with MT seems to be safe and associated with favorable functional outcomes.

Endoscopic odontoidectomy for brainstem compression in association with posterior fossa decompression and occipitocervical fusion.
Endonasal endoscopic odontoidectomy (EEO) is an alternative to transoral surgery for symptomatic ventral compression of the anterior cervicomedullary junction (CMJ), allowing for earlier extubation and feeding. Because the procedure destabilizes the C1-2 ligamentous complex, posterior cervical fusion is often performed concomitantly. The authors' institutional experience was reviewed to describe the indications, outcomes, and complications in a large series of EEO surgical procedures in which EEO was combined with posterior decompression and fusion. ⋯ EEO is safe and effective for achieving anterior CMJ decompression and is often accompanied by posterior cervical stabilization. Ventral decompression improves over time. EEO should be considered for patients with appropriate indications.

A proposed classification system for presigmoid approaches: a scoping review.
The "presigmoid corridor" covers a spectrum of approaches using the petrous temporal bone either as a target in treating intracanalicular lesions or as a route to access the internal auditory canal (IAC), jugular foramen, or brainstem. Complex presigmoid approaches have been continuously developed and refined over the years, leading to great heterogeneity in their definitions and descriptions. Owing to the common use of the presigmoid corridor in lateral skull base surgery, a simple anatomy-based and self-explanatory classification is needed to delineate the operative perspective of the different variants of the presigmoid route. Herein, the authors conducted a scoping review of the literature with the aim of proposing a classification system for presigmoid approaches. ⋯ Presigmoid approaches are becoming increasingly complex with the expansion of minimally invasive techniques. Descriptions of these approaches using the existing nomenclature can be imprecise or confusing. Therefore, the authors propose a comprehensive classification based on the operative anatomy that unequivocally describes presigmoid approaches simply, precisely, and efficiently.

Natural history of intracavernous aneurysms: a consecutive single-center study of 250 patients with 276 aneurysms.
The natural history of cavernous carotid aneurysms (CCAs) is not fully understood. For robust clinical decision-making, the behavior of CCAs needs to be fully understood. The objective of this paper was to calculate the mortality and morbidity rates of patients with diagnosed but untreated CCAs from a relatively large single-center cohort. ⋯ The majority of the CCAs were asymptomatic during follow-up, and none caused the death of the patient. The incidence of symptoms increased with aneurysm size. Because CCAs have a benign natural course, treatment should be considered mainly if the CCA is symptomatic or grows during follow-up.
