Some patients with severe brain swelling treated decompressive craniectomy may develop hydrocephalus. Consequently, these require cranioplasty and a ventriculoperitoneal (VP) shunt to relieve the However, there is no consensus as timing of VP placement in requiring both. The authors assessed results performing at same time cranial defects hydrocephalus.A retrospective review was performed 51 who had undergone operations after for refractory intracranial hypertension between 2003 2012...

The objective of this study was to investigate the morphologic characteristics between vertebral body and regions cervical thoracic spinal cords where each rootlets branch out.Sixteen adult cadavers (12 males 4 females) with a mean age 57.9 (range 33 70 years old) were used in study. anatomical relationship exit points nerve roots from posterior root entry zone at cord segment their corresponding relevant bodies also analyzed.Vertical span upper lower rootlet originating ranged 10-12 mm....

Redundant Nerve Roots (RNRs) is an uncommon clinical condition characterized by a tortuous, serpentine, large and elongated nerve root of the cauda equina. To our knowledge, most cases RNRs are associated with lumbar stenosis, disc herniation has not been reported until now. Here we present rare case unusual mimicking intradural herniation.

Objective: To compare two testing protocols for evaluating range of motion (ROM) changes in the preloaded cadaveric spines implanted with a mobile core type Charité ™ lumbar artificial disc.Methods: Using five human lumbosacral (L2-S2), baseline ROMs were measured bending moment 8 Nm all modes (flexion/extension, lateral bending, and axial rotation) intact spine.The ROM was tracked using video-based motion-capturing system.After disc at L4-L5 level, measurement repeated different methods :...

Objective Morphometric data for the lumbar posterior longitudinal ligament (PLL) was investigated to identify whether there is a difference in morphometry of PLL spine at each level with respect pattern intervertebral disc displacement. Methods In 14 formalin-fixed adult cadavers (12 males and 2 females), from L1 L5, authors measured width height compared them other landmarks such as pedicle. Results Horizontally, upper margin disc, central portion superficial covered 17.8-36.9% fan-like...

A 31-year-old man presented with acute onset of paraplegia. The patient's history was significant for thyroid carcinoma that had been treated 2 years earlier by thyroidectomy. magnetic resonance imaging scan showed an enhancing intramedullary lesion at T7-8. Patient underwent surgical treatment and a tumor hematoma resected via posterior midline myelotomy. Postoperatively, the motor weakness improved to grade 3. typical histologic features consistent papillary carcinoma. Early diagnosis...

We report 3 cases of arachnoid cysts (ACs) that completely disappeared after burr hole drainage, without cyst fenestration into the subarachnoid space or cystoperitoneal shunt. The first patient was a 21-year-old female with an AC right cerebral convexity, found incidentally. After endoscopic performed, complained persistent headache. Two-month postoperative brain imaging revealed reaccumulated and associated multi-stage subdural hematoma. Burr drainage performed to resolve chronic hematoma...

Background Two primary treatment methods are used for ruptured cerebral aneurysms, surgical clipping and endovascular coiling. In recent decades, coiling has shown remarkable progress compared to clipping, along with technological developments. The aim of this study was investigate the trends in treatments aneurysms Korea. Methods data were obtained from National Health Insurance database. We evaluated period 2000-2017. number prescriptions International Classification Diseases, 9th...

sympathectomy, but the surgical procedure required collapse of lungs by forcing air into thorax, and drew little attention due to technological limitations video imaging at that time.However, with development double-lumen endotracheal tubes recent improvement in systems, minimally invasive procedures reduce risk lung injury offer a wider field view.As result, thoracoscopic sympathectomy is typically used as approach for essential hyperhidrosis palms or axillae 4,6) .In most cases, surgery...

Spontaneous intracerebral hemorrhage (ICH) is a common condition that often leads to death or disability. Accurate prediction of the outcome and decisions regarding treatment ICH patients are important issues. We report case thalamic with an intraventricular was suddenly migrated into third fourth ventricles in its entirety 8 hours after symptom onset. To our knowledge, this first spontaneous migration ventricles, we suggest possible mechanism for brief review literature.
