Ahead of Print: Neuroendoscopic Magendie and Luschka Foraminoplasty

Screen Shot 2014-01-02 at 1.22.12 PMBackground: Routinely, hydrocephalus related to fourth ventricular outlet obstruction (FVOO) has been managed with ventriculoperitoneal (VP) shunting or endoscopic third ventriculostomy (ETV). Few reports on Magendie foraminoplasty exist, and Luschka foraminoplasty has not been described.

Objective: To present an alternative technique in the management of FVOO via an endoscopic transventricular transaqueductal Magendie and Luschka foraminoplasty and to discuss the indications, technique, findings, and outcomes.

Methods: Between 1994 and 2011, all patients who underwent endoscopic Magendie and Luschka foraminoplasty were analyzed.

Free Article: Evaluation of the 3-D Endoscope in Transsphenoidal Surgery

Screen Shot 2013-08-30 at 7.54.28 AMBackground: 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.

Methods: All patients were analyzed who had endoscopic endonasal parasellar operations since the introduction of the 3-D endoscope to our practice. Over an 18-month period, 160 operations were performed using solely endoscopic techniques. Sixty-five of these were with the Visionsense VSII 3-D endoscope and 95 utilized 2-dimensional (2-D) high-definition (HD) Storz endoscopes. Intraoperative and postoperative findings were analyzed in a retrospective fashion.

Ahead of Print: Colloid Cyst Remnants

The_Significance_of_Cyst_Remnants_FollowingBackground: Controversy surrounds the fate of cyst remnants following endoscopic colloid cyst resection.

Objective: Our study evaluated recurrence rates in patients with total endoscopic resection of colloid cysts versus those with coagulated cyst remnants.

Methods: Sixty-five consecutive patients and 67 procedures for endoscopic resection of colloid cysts from 1995 to 2011 were reviewed. Degree of resection was based upon intra-operative assessment and post-operative MRI. Recurrence rates were compared between patients with complete resection versus coagulated cyst remnants.

Ahead of Print: Fluorescein-enhanced Ventricular Endoscopy

Screen Shot 2013-03-13 at 3.55.14 PMBackground: Fluorescein enhancement to detect retinal disorder or differentiate cancer tissue in situ is a well defined diagnostic procedure. It is a visible marker of where the blood-brain barrier is absent or disrupted. Little is reported in the contemporary literature on endoscopic fluorescein-enhanced visualization of the circumventricular organs, and the relevance of these structures as additional markers for safe ventricular endoscopic navigation remains an unexplored field.

Objective: To describe fluorescein-sodium enhanced visualization of circumventricular organs as additional anatomical landmarks during endoscopic ventricular surgery procedures.

Methods: We prospectively administered 500 mg of intravenous fluorescein sodium in 12 consecutive endoscopic surgery cases. A flexible scope equipped with dual observation modes for both white light and fluorescence was used. During navigation from the lateral to the fourth ventricle, the endoscopic anatomical landmarks were first inspected under white light and then in the fluorescent mode.

Ahead of Print: Spinal Extradural Arachnoid Cysts

Background: Because idiopathic spinal extradural arachnoid cyst (SEAC) is rare, the optimal surgical treatment for SEAC remains controversial.

Objective: To evaluate the results of surgical treatments for SEAC, and to clarify features of the disease associated with poor outcomes.

Methods: Twelve patients with SEAC who underwent surgery at our hospital between 1988 and 2008 were examined retrospectively. The mean follow-up period was 4.7 years. Total resection of the cyst was performed in 7 patients, and closure of the dural defect without cyst resection in 5 patients. Surgical outcomes were evaluated with regard to the duration of symptoms, the size of the cyst, and the surgical procedure used.

Ahead of Print: Endoscopy for Isolated Fourth Ventricle

BACKGROUND: Treatment of an isolated fourth ventricle should be considered when clinical symptoms or a significant mass effect occur.

OBJECTIVE: Clinical and radiographic outcome after endoscopic transaqueductal or transcisternal stent placement into the fourth ventricle is reported.

METHODS: In 19 patients (age: 34th week of gestation – 20 years; median age: 17.5 months) 22 endoscopic procedures were carried out. Either an aqueductoplasty or – in cases with a supratentorially extended fourth ventricular component – an interventricular fenestration was performed. In all patients a stent connected to the CSF diverting shunt was placed through the fenestration. Surgical complications, and radiological and clinical outcome are reported.
