Neurologic and Neuropsychological Outcomes for Treatment of Unruptured Middle Cerebral Artery Aneurysms: Standard Pterional Versus Minipterional Approach in a Retrospective Single-Center Analysis.

Background: In accordance with technique advancement and minimal invasiveness surgical approaches, the minipterional has progressively replaced the standard pterional approach for treatment of unruptured middle cerebral artery (MCA) aneurysms. Nowadays, multimodal intraoperative resources including microDoppler and microflow probes, indocyanine green videoangiography, and neurophysiologic monitoring constitute a fundamental prerequisite for increasing the safety of the clipping procedure. Our study investigated and compared in a single-center experience the effect of the evolution of a minimally invasive and multimodal approach in unruptured MCA aneurysm surgery by measuring postoperative complication rate, recovery time, and long-term neuropsychological and functional outcomes.

Hydrocephalus and the First Report of an External Ventriculostomy: The Contributions of Fabrici d'Acquapendente in the Italian Renaissance.

In our historical study, we are unveiling one of the very first surgical treatments of hydrocephalus originally scripted in Latin by Fabrici d'Acquapendente and then transcribed into the French language by Chez Pierre Ravaud. During the European Renaissance, Italian pioneering surgeon Fabricid'Acquapendente illustrated the technique performed at that time. Fabrici described the drainage of fluid for hydrocephalus using the insertion of a cannula.

Spinal Epidural Atypical Meningioma: Case Report and Review of the Literature.

Spinal atypical meningiomas are rare, and those whose main extension is in the epidural space are anecdotal. Here, we report a case of a young woman presenting with sensory disturbances and a radiological diagnosis of a dorsal epidural sleeve-like mass. The surgical resection of the lesion allowed the decompression of the spinal cord and led to the histopathological diagnosis of atypical meningioma.

Combined Use of Color Doppler Ultrasound and Contrast-Enhanced Ultrasound in the Intraoperative Armamentarium for Arteriovenous Malformation Surgery.

Background: Safety and efficacy in surgical treatment of cerebral arteriovenous malformations (AVMs) are dictated by thorough understanding of angioarchitectural features, intraoperative identification of feeding vessels, and appreciation of surrounding eloquent areas. Our aim was to describe the preliminary results of combined application of color Doppler ultrasound (CDUS) and contrast-enhanced ultrasound (CEUS) in a consecutive surgical series of AVM. We pointed out the tool's efficacy in distinguishing feeding from bystander vessels and in identifying pattern of venous drainage.

Retrospective Application of UIATS Recommendations to a Multicenter Cohort of Ruptured Intracranial Aneurysms: How It Would Have Oriented the Treatment Choices?

Background: Decisions to treat unruptured intracranial aneurysms remain challenging, as the risk of rupture needs to be balanced with risk of intervention. In 2015, the Unruptured Intracranial Aneurysm Treatment Score (UIATS) was introduced to assist physicians in the decision making process. As its reliability is still debated, we retrospectively applied UIATS to a multicenter cohort of aneurysmal subarachnoid hemorrhage patients to test its performance in suggesting treatment in patients with known natural history.

Comparison Between Minipterional Craniotomy Associated With Focused Sylvian Fissure Opening and Standard Pterional Approach With Extended Sylvian Fissure Dissection for Treatment of Unruptured Middle Cerebral Artery Aneurysms.

Background: In our institution, standard pterional craniotomy (PC) with an extended Sylvian fissure opening (ESFO) represented the standard approach for unruptured middle cerebral artery (MCA) aneurysm clipping until 2014, when we progressively started to prefer minipterional craniotomy (MPC) associated with a focused Sylvian fissure opening (FSFO). In the present study, we compared our results in terms of the efficacy of clipping and the rate of complications with these 2 different techniques.

Methods: We included patients with small- and medium-size unruptured MCA aneurysms from January 2008 to December 2018 with follow-up of >12 months.

Retrospective application of risk scores to ruptured intracranial aneurysms: would they have predicted the risk of bleeding?

As the incidental diagnosis of unruptured intracranial aneurysms has been increasing, several scores were developed to predict risk of rupture and growth to guide the management choice. We retrospectively applied these scores to a multicenter series of patients with subarachnoid hemorrhage to test whether they would have predicted the risk of bleeding in the event of aneurysm discovery previous to its rupture. Demographical, clinical, and radiological information of 245 adults were retrieved from two neurovascular centers' database.

Medical Student Interest and Recruitment in Neurosurgery.

Objective: Recent years have witnessed an increase in articles describing factors influencing medical student recruitment in neurosurgery, such as undergraduate preparation, impact of research experience, and selection into residency programs. In this study, we provide a comprehensive review of the literature addressing the relationship of medical students within neurosurgery.

Methods: A search of the literature was conducted on the PubMed/MEDLINE database to October 2018 to screen for studies on medical student interest and recruitment in neurosurgery.
