JOURNAL ARTICLE
J Y Cho, S-H Lee, H-Y Lee
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. When POD occurs, even if the traversing root has been successfully decompressed, it hinders swift recovery and delays the return to daily routines...

BACKGROUND: Radiosurgical management of large cystic metastatic brain tumors represents a significant challenge. Nevertheless, modified dose planning has shown beneficial results in such cases. METHOD AND RESULTS: "Donut's shape" radiosurgical treatment planning is based on the chain-like application of multiple, small-sized isocenters for selective coverage of the contrast-enhancing tumor capsule and minimal irradiation of the central cystic area. Such an approach was used for the management of large cystic intracranial metastases, which were not accompanied by a significant mass effect and did not require immediate volume reduction...

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...

JOURNAL ARTICLE
V Waran, K Sek, N F Bahuri, P Narayanan, H Chandran
In endoscopic neurosurgery problems with haemostasis due to poor access exist. We have developed a system which allows the delivery of a variety of haemostatic agents in a more efficacious manner. The system has been used successfully in endoscopic skull base surgery and endoscopic surgery within the parenchyma of the brain using tube systems.

JOURNAL ARTICLE
T Menovsky, D De Ridder
Microsuturing in a narrow and/or a deep operating space is technically challenging and classical microinstruments such as a bayonet microneedle-holder have their limitation, mainly related to their in-built rigidity. In this technical note, a new flexible and 360° rotating shaft microneedle-holder made from nitinol is presented.

BACKGROUND: Parenchymal hemorrhage is one of the most feared risks of stereotactic brain biopsies potentially resulting in neurological deficits or even a fatal outcome. Patients with disorders of the coagulation system are at particular risk, so identifying these is one of the main tasks prior to surgery. Some patients may have a bleeding tendency despite normal laboratory values of the hemostatic system. CASE REPORT: We report the case of a patient with coagulopathy of unclear etiology undergoing a stereotactic brainstem biopsy...

BACKGROUND: Bony defects extending laterally or superiorly within the posterior wall of the frontal sinus are generally deemed too difficult for endoscopic repair in spite of significant progress in surgical endoscopic techniques. PATIENTS AND METHODS: We describe a technique of endoscopic repair of posttraumatic cerebrospinal fluid (CSF) leak from the postero-superior aspect of the frontal sinus in a 40- and a 29-year-old male. In both cases after careful assessment of the surgical anatomy the sinus was widely opened transnasally (Draf IIB and Draf III approach, respectively)...

BACKGROUND: Lesions originating in the vidian canal are extremely rare. Most frequently, they are extensions from contiguous carcinomas. We present a rare case of a vidian nerve neurofibroma and discuss its surgical management. CASE REPORT: A 62-year-old woman with a history of a basal cell skin cancer was evaluated for bilateral tinnitus. Imaging revealed a left-sided lesion at the medial aspect of the pterygoid process base, over the vidian canal. Under image-guidance, an endonasal endoscopic transpterygoid approach was performed...

JOURNAL ARTICLE
G B de Aguiar, M L M Conti, J C E Veiga, M Jory
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...

JOURNAL ARTICLE
D A Chesler, C Pendleton, G I Jallo, A Quiñones-Hinojosa
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...

BACKGROUND: In spinal cord stimulation (SCS) mainly 2 distinctive implantation techniques can be recognized: the percutaneous and surgical technique. MATERIAL AND METHODS: A puncture is made with a blunt 14 gauge Tuohy needle. Once inside the epidural space the guide wire needs to be advanced in the epidural space, then the Tuohy needle is removed. The Epiducer is advanced under the guidance of lateral fluoroscopy, to confirm epidural entry. The S-series electrode is introduced through the sheet in the epidural space...
