Managing Arterial Injury in Endoscopic Skull Base Surgery: Case Series and Review of the Literature.

Background: The most feared complications following endoscopic endonasal skull base surgery are arterial vascular injuries. Previously published literature is restricted to internal carotid artery injuries. The ideal method for controlling arterial bleeding during this kind of procedure is debated, and a variety of techniques have been advocated.

Severe Edema and Venous Congestion Following Sphenoorbital Meningioma Resection in a Meningiomatosis Case: Importance of Predicting Venous Disturbances.

To achieve local disease control, radical removal is the best option for sphenoorbital meningiomas. Preservation of the venous system is crucial during the resection of skull base meningiomas. This vascular injury represents a major risk both for life and neurologic function.

Evaluation of the 3-dimensional endoscope in transsphenoidal surgery.

Background: Three-dimensional (3-D) endoscopy is a recent addition to augment the transsphenoidal surgical approach for anterior skull-base and parasellar lesions. We describe our experience implementing this technology into regular surgical practice.

Objective: Retrospective review of clinical factors and outcomes.

The distance between the posterior communicating arteries and their relation to the endoscopic third ventriculostomy in adults: An anatomic study.

Background: The diencephalic leaf of the Liliequist's membrane is a continuous structure that should be perforated in the endoscopic third ventriculostomy. Its lateral borders are penetrated by the third cranial nerve and the posterior communicating arteries. The most important complication of endoscopic third ventriculostomy is the vascular injury, such as the posterior communicating artery.

Quantitative ventricular neuroendoscopy performed on the third ventriculostomy: anatomic study.

Background: One of the key elements for a successful endoscopic intervention in the ventricular system is the ability to recognize the anatomic structures and use them as a reference.

Objective: To measure the choroid plexus with endoscopy in the interventricular foramen, together with the structures on the third ventricle floor, and to compare these variables.

Methods: An observational prospective study was carried out on 37 brains of cadavers for which the cause of death was assessed at the Death Check Unit of the University of São Paulo in April 2008.

Cerebrospinal fluid fistula after endoscopic transsphenoidal surgery: experience in a spanish center.

Background: Postoperative cerebrospinal fluid (CSF) fistula is the most serious complication after transsphenoidal surgery.

Objective: To analyze the incidence of CSF fistula after endoscopic transsphenoidal surgery for tumor removal in sellar region; to discuss associated factors and methods used for sellar closure.

Method: Retrospective study of 67 patients (73 surgeries) operated via transsphenoidal endoscopy at Hospital Vall D'Hebron and Hospital Clinic of the Universidad de Barcelona, Spain.
