Primary Dural Closure in Minimally Invasive Spine Surgery Using an Extracorporeal Knot: Technical Note.

Background: Minimally invasive spine surgeries (MISS) are currently used for a wide variety of intradural spinal pathologies. Although MISS techniques have brought great benefits, primary dural closure can prove a challenge due to the narrow corridor of the tubular retractor systems.

Objective: To present the surgical technique we developed for dural closure using an extracorporeal knot that is simple and reproducible.

[Intramedullary neuroenteric cyst: Case report and review of the literature].

Neurenteric cysts (NC) are rare, benign, congenital lesions, caused by abnormal or persistent communications between neuroectodermal structures, the notochord and endodermal tissue. They present mainly in the pediatric population or young adults, coexisting with spinal, gastrointestinal or respiratory malformations. They are typically intradural extramedullary tumors, with intramedullary lesions the exception.

"Live Cadaver" Model for Internal Carotid Artery Injury Simulation in Endoscopic Endonasal Skull Base Surgery.

Background: Intraoperative injury of the internal carotid artery (ICA) is the most dreaded complication in endoscopic endonasal surgery (EES) of skull base. Training for ICA injury is practically impossible in live operative settings.

Objective: To evaluate a pulsatile perfusion-based live cadaveric model for ICA injury simulation in a laboratory setting.
