The effectiveness of lumbar cerebrospinal fluid drainage to reduce the cerebral vasospasm after surgical clipping for aneurysmal subarachnoid hemorrhage.

Objective: Removal of blood from subarachnoid space with a lumbar drainage (LD) may decrease development of cerebral vasospasm. We evaluated the effectiveness of a LD for a clinical vasospasm and outcomes after clipping of aneurysmal subarachnoid hemorrhage (SAH).

Methods: Between July 2008 and July 2013, 234 patients were included in this study.

Large Ossified Rathke's Cleft Cyst - A Case Report and Review of the Literature -.

We report a rare case of symptomatic Rathke's cleft cyst with thick calcified wall. Brain CT scans revealed a large cystic mass with round thick calcified wall. In this case, we selected the pterional approach instead of transsphenoidal approach due to the possibility of cystic craniopharyngioma.

Aneurysms of distal posterior inferior cerebellar artery.

Objective: Aneurysms are very rarely encountered in the distal posterior inferior cerebellar artery (PICA). The authors experienced 5 cases with a distal PICA aneurysm among 368 cases of intracranial aneurysms during the period from January 2003 to January 2008. Here, the authors describe their clinical and surgical experiences and include a review of the relevant literature.

Hydrothorax due to migration of ventriculoperitoneal shunt catheter.

A cerebrospinal fluid hydrothorax is a very rare complication following ventriculoperitoneal (VP) shunt and usually reported in children. We report a case of 47-year-old woman who developed massive hydrothorax and respiratory distress following intrathoracic migration of distal shunt catheter. After the confirmation of catheter in thoracic cavity using radionuclide shuntogram, the patient was successfully treated with laparoscopic shunt catheter reposition.

Unusual Intracranial Parasagittal Meningioma Extending into the Internal Jugular Vein through the Sinuses.

Meningiomas frequently invade cerebral venus sinuses, especially parasagittal meningioma to superior sagittal sinus. However, most invasions do not reach internal jugular vein. We present a case of parasagittal meningioma extending into the internal jugular vein through the sinuses.

Quantitative anatomical and morphological classification of the iliac vessels anterior to the lumbosacral vertebrae.

Object: Anterior surgical approaches to the lumbosacral disc spaces are being undertaken with increasing frequency. This increase and the use of minimally invasive techniques themselves have the potential to raise the incidence of major vessel injuries. The purpose of this study was to determine the variability of the vascular anatomy anterior to the lumbosacral spine and to draw conclusions regarding surgical accessibility of the L5-S1 disc space.
