Lumbar Puncture for the Injection of Intrathecal Fluorescein: Should It Be Avoided in a Subset of Patients Undergoing Endoscopic Endonasal Resection of Sellar and Parasellar Lesions?

摘要

The use of intrathecal fluorescein (ITF) has become an increasingly adopted practice for the identification of cerebrospinal fluid (CSF) leaks during endoscopic skull base surgery for pituitary adenomas. Administration through lumbar puncture can result in postoperative positional headaches, increasing morbidity, cost, and length of stay. We sought to identify the incidence of and variables associated with postoperative headaches to determine if there was a subgroup of patients in whom this procedure should be avoided.
