INTRODUCTION Neurointerventional procedures have traditionally been performed via transfemoral access. However, according to interventional cardiology literature, transradial access can have decreased access site complications and possibly decreased mortality compared to transfemoral access. Reported limitations for wide adoption of transradial access in neurointerventional procedures include the learning curve. METHODS All neurointerventional procedures performed at a single institution with a transradial first approach were identified from Aug 2017 to January 2020. Demographic and clinical information were identified. Access site complications were recorded. Univariate analysis was performed to identify predictors of transradial failure. Covariates with P < .15 were inputted into a multivariate model with statistical significance set at P < .05. RESULTS A total of 350 transradial neurointerventional procedures were performed in 313 patients. The mean age was 68.2 years and 51% female. Most procedures (95%) used 6F radial sheaths for access. Biaxial system (e.g. microcatheter and microwire) was used in most procedures (61%). There were 81 aneurysm interventions, 73 embolization procedures, 69 angioplasty/stenting procedures, 116 mechanical thrombectomies including 93 involving the anterior circulation, and 11 vasospasm treatments. There was a remarkably high procedure completion rate with a transradial approach (96%, 335/350). Thirteen procedures were converted to transfemoral access (3.7%), 1 procedure converted to transbrachial access, and 1 procedure aborted completely. On multivariate analysis, decreasing age, female gender, and left-sided target artery were predictive of transradial failure. Radial access site complications were extremely rare (0.6%, 2/350 - 1 forearm hematoma, 1 radial artery occlusion). CONCLUSION In a high-volume endovascular center, transradial approach to a wide variety of neurointerventional procedures is both safe and feasible. Predictors of transradial failure include decreasing age, female gender, and left-sided target artery.

BACKGROUND: Infection from the SARS-CoV-2 virus has led to the COVID-19 pandemic. Given the large number of patients affected, healthcare personnel and facility resources are stretched to the limit; however, the need for urgent and emergent neurosurgical care continues. This article describes best practices when performing neurosurgical procedures on patients with COVID-19 based on multi-institutional experiences. METHODS: We assembled neurosurgical practitioners from 13 different health systems from across the USA, including those in hot spots, to describe their practices in managing neurosurgical emergencies within the COVID-19 environment. RESULTS: Patients presenting with neurosurgical emergencies should be considered as persons under investigation (PUI) and thus maximal personal protective equipment (PPE) should be donned during interaction and transfer. Intubations and extubations should be done with only anesthesia staff donning maximal PPE in a negative pressure environment. Operating room (OR) staff should enter the room once the air has been cleared of particulate matter. Certain OR suites should be designated as covid ORs, thus allowing for all neurosurgical cases on covid/PUI patients to be performed in these rooms, which will require a terminal clean post procedure. Each COVID OR suite should be attached to an anteroom which is a negative pressure room with a HEPA filter, thus allowing for donning and doffing of PPE without risking contamination of clean areas. CONCLUSION: Based on a multi-institutional collaborative effort, we describe best practices when providing neurosurgical treatment for patients with COVID-19 in order to optimize clinical care and minimize the exposure of patients and staff.
