Prevertebral soft tissue swelling (PSTS) is a known complication of anterior cervical fusion (ACF). Prior studies have shown that perioperative steroids may reduce PSTS after ACF. We retrospectively evaluated the role of perioperative intravenous (IV) corticosteroid administration in minimizing radiographic PSTS measurements in patients undergoing ACF for degenerative disease. ⋯ There does not appear to be a role for perioperative IV steroid administration in minimizing radiographic PSTS in patients undergoing ACF for degenerative disease. The relationship between perioperative IV steroid administration and PSTS requires further investigation.

Acquired (nontraumatic) brain herniation through the ethmoid is rarely associated with an intracranial mass away from the anterior skull base. A 55-year-old diabetic woman presented with progressive frontal headache, anosmia, and blurred vision without rhinorrhea. Brain magnetic resonance imaging showed an intracranial tumor of the left frontal convexity associated with a herniation of the frontal brain (encephalocele) into the left nasal cavity. ⋯ Pathologic examination revealed a meningothelial meningioma. However, the patient and her family refused any surgery for the ethmoidal encephalocele. In our case report, this rare phenomenon (secondary nontraumatic encephalocele) probably occurred due to long-term increase of the intracranial pressure generated by the meningioma.

The natural history and the outlook of patients with hydrocephalus are dramatically affected using cerebrospinal fluid shunts. The several issues related with a long-standing shunt should suffice to justify all the possible attempts to free the patient from it. This study focused on the role of secondary endoscopic third ventriculostomy (ETV) in the achievement of shunt removal in cases of shunt malfunction, and to identify patients who could benefit most from the procedure. ⋯ Many patients with shunt malfunction can benefit from secondary ETV even after decades of shunting. Age at secondary ETV, the number of previous shunt revisions, and the ETV success score can help to better identify the best candidates for the procedure.

The number of endovascular treatment procedures performed for cerebral aneurysms has markedly increased. However, little is known about the annual effective radiation dose to medical staff in neurointervention fields. We performed a retrospective observational study to investigate the real-time radiation dose to surgeons, nurses, anesthesiologists, and radiologic technologists during endovascular treatment of intracranial aneurysms. ⋯ We confirmed the differences in the amount of radiation exposure for different roles. An additional lead screen, which provided more effective protection on the operator side, was proved effective for attenuating radiation exposure during endovascular treatment. All personnel involved in the hybrid operating room were exposed to acceptable effective doses.

and importance: Epistaxis is a rare presentation of the ruptured cavernous carotid aneurysm (CCA) especially nontraumatic type. Both endovascular therapies and open surgeries have a role in the treatment with various outcomes, but the standard procedure is not well established. We report a successful high-flow bypass with cervical internal carotid artery ligation for aneurysm repair and review the related literature. ⋯ In cases of massive or recurrent epistaxis without coagulopathy or nasal pathology, a CCA should be considered. Immediate cessation of bleeding is necessary. Flow-preservation bypass with proximal ligation of the parent artery is one of the effective procedures for the treatment of this condition with low morbidity.
