Background: The type of sellar barrier observed between a pituitary tumor and cerebrospinal fluid (CSF) on preoperative magnetic resonance imaging (MRI) may predict intraoperative CSF leak during endonasal pituitary surgery. This is the first multicentric prospective cohort trial to study the sellar barrier concept and CSF leak rate during endoscopic pituitary surgery.
Methods: This multi-center, international study enrolled patients operated for pituitary adenomas via fully endoscopic endonasal surgery over a period of 4 months.
Objectives/hypothesis: The goal of this study was to present a classification based on the degree of pneumatization of the sphenoid sinus in the coronal plane that can be used to instruct preoperative planning for endoscopic endonasal surgery (EES).
Study Design: Observational anatomical study.
Methods: The geometry of sphenoid sinus pneumatization was characterized (n = 204 hemisinus) on high-resolution computed tomography scans, and its associations with the location of the foramen rotundum (FR) and the vidian canal (VC) were measured.
Background: Radiosurgery has been widely used to treat cerebral AVMs, providing angiographic evidence of obliteration of the malformation in 80% to 95% of patients, after a latency period of 2 to 5 years.
Case Description: We describe a case of hemorrhage, 6 years after radiosurgery and 4 years after complete angiographic obliteration of an AVM that had not previously bled and that persisted angiographically, obliterated after bleeding.
Results: Several treatment options have been reported for patients with completely obliterated AVMs that bled, including conservative treatment, repeated radiosurgery, and open surgery with resection of AVM remnants.
