Syamala Shunmugam, Thas Emmanuel, Shyam Duvuru
Traumatic aneurysm rupture following a closed head injury is rare. The rupture of a cavernous internal carotid artery (ICA) aneurysm following a head injury presenting as a tentorial subdural hematoma has not been reported in the literature. We discuss a 50-year-old woman with a closed head injury with her initial computed tomography scan showing a tentorial subdural hematoma. Further investigations revealed the presence of a ruptured cavernous ICA aneurysm. We also conducted a literature review of posttraumatic ICA aneurysmal rupture...

Spasticity of cerebral or spinal origin severely impairs an individual's functional ability and quality of life. Intrathecal baclofen (ITB) therapy via an implantable pump is indicated for use in patients unresponsive to oral antispasmodics. ITB therapy improves the daily caring for and relief of painful spasms. In Lithuania, ITB therapy was introduced in clinical practice just recently. We share our experience of spasticity management with the ITB pump system in five patients at Vilnius University Hospital Santariskiu Klinikos...

Background The piezo actuator-driven pulsed water jet (ADPJ) system is a novel surgical instrument that enables dissection of tissue without thermal damage. Using the ADPJ system in epilepsy surgery requires prediction of the tissue breaking strength of the epileptic brain. The aim of this study was to elucidate whether magnetic resonance imaging T2 relaxometry could predict the breaking strength. Methods A total of 12 patients with drug-resistant temporal lobe epilepsy who received surgical treatment were included in the study...

Background The treatment of brain arteriovenous malformations (AVMs) has been studied extensively. With the use of the Spetzler-Martin (S-M) grading system, patients can be informed appropriately about their possible surgical risks. This does not hold true for their neuropsychological sequelae, which have not been studied widely. We evaluated the neuropsychological outcome of our patients treated for brain AVMs. Methods Of 113 patients treated for a brain AVM between 2001 and 2009, 66 patients were enrolled in the study...

Qingde Wang, Kezheng Mao, Chunli Wang, Wei Mei
Background Prior studies have mainly assessed transoral odontoidectomy for basilar invagination with irreducible atlantoaxial dislocation. However, studies evaluating transoral release and posterior reduction with occipitocervical fixation in this setting are scarce. Methods From 2008 to 2013, 11 patients (6 men and 5 women; 23-67 years of age) with basilar invagination and irreducible atlantoaxial dislocation underwent surgery. They presented signs and symptoms of myelopathy or significant spinal cord injury, and were treated by transoral soft tissue release without odontoidectomy, under skull traction with heavy weight and by posterior reduction with occipitocervical plate fixation...

Background and Study Aims In microvascular decompression of the trigeminal nerve for trigeminal neuralgia (TN), the site of conflict is occasionally difficult to identify. Endoscopy has been described to better evaluate the anatomical conflict in such situations. We hypothesized that indocyanine green (ICG) angiography could allow for better visualization of the compressing artery and its anatomical relation to the nerve. Material and Methods ICG angiography was performed in 17 TN patients undergoing microvascular decompression...

Ko Ikuta, Kiyoshi Tarukado, Keigo Masuda
Background and Study Aims Microendoscopic diskectomy (MED) has become an established minimally invasive procedure in surgical treatment for lumbar disk herniation (LDH). LDH recurrence following surgery is also an important problem in MED because the risk of LDH recurrence may surpass the advantages of MED. The purpose of this study was to investigate the characteristics of recurrence following MED for LDH and identify the risk factors for a recurrence. Materials and Methods A total of 163 patients who underwent MED for LDH and could be followed for a minimum of 1 year after surgery were enrolled in this study (follow-up [FU] rate: 79...

Sang Soo Eun, Jin Hwa Eum, Sang Ho Lee, Luigi Andrew Sabal
Background and Study Aims Endoscopic lumbar diskectomy through the interlaminar window is gaining recognition. Most of the literature describes these endoscopic procedures using specialized uniportal multichannel endoscopes. However, a single portal limits the motion of the instruments and obscures visualization of the operating field. To overcome this limitation, we propose a new technique that utilizes two portals to access the spinal canal. The biportal endoscopic lumbar decompression (BELD) technique uses two portals to treat difficult lumbar disk herniations and also lumbar spinal stenoses...
