The Operative Neurosurgery journal has undergone a rich transformation in the past several years under the creative vision of its editor, Dr. Nelson Oyesiku. It has evolved into a separate publication with a variety of robust content including operative procedures, instrumentation, and case series featuring 2D and 3D videos, high-quality anatomic and surgical illustrations, and more. The recent expansion of its digital platform has allowed for its most recent transformation, the birth of Operative Neurosurgery: The Surgeon’s Armamentarium (ONS-SA). This unique and sophisticated digital content delivery system utilizes a robust search engine to deliver essential operative content from its repository to your fingertips in real time. The versatility and depth of ONS-SA will be demonstrated in two live surgery sessions at the upcoming CNS Annual Meeting.
The Monday afternoon session, Live Neuroendovascular Surgery: Novel Devices and Treatment Controversies, will compare different neuro-endovascular technology such as new flow diverters and intraaneurysmal devices in aneurysms with identical geometry, and different techniques for mechanical thrombectomy. The procedures will utilize live demonstrations with the VascSim simulator (Figure 1), and will be performed by an expert advocate for that technology, and in some cases, its inventor. We will highlight high-impact endovascular technique articles in Operative Neurosurgery which complement these simulator models.
Figure 1: The VascSim Simulations (LLC) Replicator
The Vascular Simulations (LLC) Replicator is an artificial replica of the left side of the heart and the arterial tree. Arterial vessels can also be modeled from clinical imaging such as CTA, MRA, or rotational angiography such that the geometry of an intracranial aneurysm is identical to that of the patient. Endovascular techniques can then be tested, practiced, or compared prior to the actual treatment of the aneurysm.
Endonasal Pituitary Case: Live Surgery
This is a live endoscopic endonasal surgery for resection of a large pituitary adenoma. This Tuesday afternoon session will cover the endonasal endoscopic surgical approach, tumor resection, reconstruction techniques, and methods to maximize efficiency of the neurosurgery and otolaryngology team during concurrent surgery. Particular emphasis will be placed on techniques for the preservation of normal sinonasal structures and function, while achieving maximal tumor resection. The tagged and searchable 3D endoscopic pituitary video content from Operative Neurosurgery was highly cited and will be used to review the surgical techniques used to preserve normal sinonasal structures and function.
