Prevention of development of postoperative dysesthesia in transforaminal percutaneous endoscopic lumbar discectomy for intracanalicular lumbar disc herniation: floating retraction technique.

Minim Invasive Neurosurg 2011 Oct 27;54(5-6):214-8. Epub 2012 Jan 27.

Department of Neurosurgery, Wooridul Spine Hospital, Seoul, Korea.

Background: Transforaminal percutaneous endoscopic lumbar discectomy (PELD) has become a routine surgical procedure because it is minimally invasive. Perioperative complications such as dural injury, infection, nerve root irritation and recurrence can occur not only with PELD, but also with conventional open microsurgery. In contrast, post-operative dysesthesia (POD) due to existing dorsal root ganglion (DRG) injury is a unique complication of PELD. Read More

Skull bone flap fixation - reliability and efficacy of a new grip-like titanium device (Skull Grip) versus traditional sutures: a clinical randomized trial.

Minim Invasive Neurosurg 2011 Oct 25;54(5-6):282-5. Epub 2012 Jan 25.

Department of Neurosurgery, Service de Neurochirurgie, Hopital Lariboisière, 75475 Paris Cedex 10, France.

Background: After completing a craniotomy, it is important to replace the removed bone flap in its natural position in order to guarantee brain protection as well as improve cosmesis. A skull defect can expose the brain to accidental damage, and in cases of larger defects it may also cause the patients psychosocial problems. The ideal fixation device should provide reliable attachment of the flap to the skull and promote fast bony healing to avoid possible pseudo-arthrosis and/or osteolytic changes. Read More

Giant intracranial pial arteriovenous fistula treated by endovascular intervention.

Minim Invasive Neurosurg 2011 Oct 25;54(5-6):247-9. Epub 2012 Jan 25.

Department of Surgery, Division of Neurosurgery, Santa Casa Medical School, São Paulo, Brazil.

Introduction: Arteriovenous fistulas (AVF) are rare vascular lesions of the brain that differ from arteriovenous malformations as they present a direct connection between artery and vein, without interposition of the nidus. They are fed by one or more arterial branches, with a single draining vein. Clinically they can be revealed through cerebral hemorrhage, convulsive crisis, neurological deficit, heart failure in neonates and infants, headache, bruit, or intracranial hypertension symptoms.

"Colossal" breakthrough: the callosal puncture as a precursor to third ventriculostomy.

Minim Invasive Neurosurg 2011 Oct 25;54(5-6):243-6. Epub 2012 Jan 25.

The Johns Hopkins University School of Medicine, Department of Neurosurgery and Oncology, Baltimore, MD, USA.

Background: In 1908, Anton and von Bramann proposed the Balkenstich method, a corpus callosum puncture which created a communication between the ventricle and subarachnoid space. This method offered the benefit of providing continuous CSF diversion without the implantation of cannula or other shunting devices, yet it received only slight reference in the literature of the time. It remained a novel and perhaps underutilized approach at the time Cushing began expanding his neurosurgical practice at the Johns Hopkins Hospital. Read More

Minimally invasive technique for decompression of lumbar foraminal stenosis using a spinal microendoscope: technical note.

Minim Invasive Neurosurg 2011 Jun 23;54(3):142-6. Epub 2011 Aug 23.

Department of Orthopaedic Surgery, Sapporo Medical University School of Medicine, Sapporo, Hokkaido, Japan.

Background: Lumbar foraminal stenosis is a troublesome disease. Decompression of the whole length of the nerve root from the spinal canal to extraforaminal zone is often a surgical requirement due to the difficulty in identifying the nerve compression site before surgery, making preservation of the posterior elements difficult. The authors report a minimally invasive microendoscopic technique for lumbar foraminal stenosis to decompress the entire length of the nerve root from the spinal canal to the extraforaminal zone while preserving the posterior elements.

Preoperative evaluation of the deep cerebral veins using 3-tesla magnetic resonance imaging.

Minim Invasive Neurosurg 2011 Jun 23;54(3):105-9. Epub 2011 Aug 23.

Department of Neurosurgery, Tohoku University Graduate School of Medicine, Sendai, Miyagi, Japan.

Background: Surgical treatment of deep-seated tumors such as supratentorial intraventricular and thalamic-pineal-tectal region tumors carries a risk of postoperative deficits due to possible damage to deep cerebral veins including the internal cerebral vein. It is often difficult to identify whether the vessel encountered during surgery needs to be preserved or not through the small operative field. Therefore, preoperative evaluation of deep venous structures is important. Read More
