BACKGROUND: Simulation training has been shown to be an effective teaching tool. Learner management of an intraoperative crisis such as a major cerebrovascular bleed requires effective teamwork, communication, and implementation of key skill sets at appropriate time points. This study establishes a first of a kind simulation experience in a neurosurgery/anesthesia resident (learners) team working together to manage an intraoperative crisis. METHODS: Using a cadaveric cavernous carotid injury perfusion model, 7 neurosurgery and 6 anesthesia learners, were trained on appropriate vascular injury management using an endonasal endoscopic technique...

INTRODUCTION: Neurosurgeons face the highest probability of facing a medical malpractice claim of any specialist. Here, we perform the first specialty-wide review of malpractice claims in neurosurgery using a well-established, national, online legal database. MATERIALS AND METHODS: The Westlaw (Thomson Reuters, New York) legal service was queried for jury verdicts and settlements related to neurosurgery and medical malpractice from 1985 to 2015. Case files were examined and factors recorded included the age and sex of the patient, the state and year in which the verdict was reached, defendant specialties, award payouts, and alleged reasons for malpractice...

BACKGROUND: The middle temporal artery (MTA) is the proximal medial branch of the superficial temporal artery (STA), supplying the temporalis muscle along with deep temporal arteries. Its use in vascularized flaps for reconstructive and otologic procedures has been described, yet its potential use in neurosurgery is not studied. We report a novel technique for exposing the MTA and evaluated its characteristics for extracranial-intracranial (EC-IC) cerebrovascular bypass. METHODS: After a curvilinear frontotemporal incision in 10 cadaveric specimens, the STA was dissected from distal to proximal...

BACKGROUND: Prospective studies of unruptured aneurysms have shown very low rates of rupture for small aneurysms (<10 mm) and suggested that the risk of treatment outweighs benefit. However, common clinical practice shows that patients with aneurysmal subarachnoid hemorrhage (aSAH) frequently have small aneurysms. OBJECTIVE: To investigate trends in size and location of ruptured aneurysms over a 25-yr period. METHODS: A prospective, Institutional Review Board-approved database of all patients presenting to our institution with aSAH from 1991 to 2016 was analyzed...

Advances in robotic medicine have been adopted by various surgical subspecialties as the benefits of this technology become more readily apparent: precision in narrow operative windows, tremor controlled movements, and modestly improved outcomes, among others. Vascular neurosurgery, in particular, remains open to newer and more cutting edge treatment options for complex pathologies, and robotics may be on the horizon for such advances. We seek to provide a broad overview of these innovations in vascular neurosurgery for both practitioners well acquainted with robotics and those seeking to become more familiar...
