Difficulties in giant intracranial aneurysm surgery are the consequence of aneurysmal wall histology and the complex angioarchitecture of the vascular tree. In order to reduce complications and risks of those procedures, various imaging and electrophysiological techniques can be implemented perioperatively. The authors review the principles, goals and main results in this context of micro-Doppler and flowmeter techniques, near-infrared spectroscopy, operative microscope-integrated indocyanine green video-angiography, neuro-endoscopy, selective intraoperative angiography and electrophysiological monitoring...

Invasive aspergillosis causing orbital apex syndrome (OAS) in an immune-competent individual is a very rare phenomenon, scarcely reported in medical literature. A 68-year-old male presented with progressive loss of vision in the right eye, starting after a cataract surgery. Neurological examination suggested OAS. Imaging was suggestive of mass lesion causing destruction of ethmoid bone. Biopsy of the lesion could not be done initially in view of its proximity to the major neuro-vascular bundle in the orbital apex and cavernous sinus and the major risk involved in the procedure relative to its yield...

Object Neonatal intraventricular hemorrhage (IVH) may evolve into posthemorrhagic hydrocephalus and cause neurodevelopmental impairment. In this study, an endoscopic surgical approach directed toward the removal of intraventricular hematoma was evaluated for its safety and efficacy. Methods Between August 2010 and December 2012 (29 months), 19 neonates with posthemorrhagic hydrocephalus underwent neuro endoscopic lavage for removal of intraventricular blood remnants. During a similar length of time (29 months) from March 2008 to July 2010, 10 neonates were treated conventionally, initially using temporary CSF diversion via lumbar punctures, a ventricular access device, or an external ventricular drain...

We report a case of mixed adenoendocrine carcinoma of the upper thoracic esophagus arising from ectopic gastric mucosa. A 64-year-old man who had been diagnosed with an esophageal tumor on the basis of esophagoscopy was referred to our hospital. Upper gastrointestinal endoscopy revealed the presence of ectopic gastric mucosa and an adjacent pedunculated lesion located on the posterior wall of the upper thoracic esophagus. Subtotal esophagectomy with three-field lymph node dissection was performed. A microscopic examination revealed that there was a partially intermingling component of neuroendocrine carcinoma adjacent to a tubular adenocarcinoma which was conterminous with the area of the ectopic gastric mucosa...

INTRODUCTION: Neurosurgery is a rapdily evolving speciality and has often taken a lead in adopting new technologies. Advancing technology however is not the only force driving change in this discipline. Other factors include an escalation in patient expectations, an increasing (and ageing) population and the prevailing economic conditions. The aim of our study was to analyse the trends in neurosurgical practice over a 10-year period. MATERIALS AND METHODS: The details of every neurosurgical procedure performed at Wellington Regional Hospital from 2001 to 2011 were prospectively recorded in a relational database...

BACKGROUND/AIMS: Microvascular decompression (MVD) of the trigeminal nerve is a widely accepted treatment for patients with trigeminal neuralgia caused by vascular compression. The neuroendoscope is rapidly becoming a complementary tool in minimally invasive neurosurgery of the ventral anterior skull base. Its adoption in the lateral approach to the posterior fossa has been slower and has been used primarily as an adjunct to conventional microscopic surgical techniques, e.g. endoscope-assisted microsurgery...

BACKGROUND: Open surgical approaches to intraventricular tumours are complex and challenging. Neuro-endoscopy, however, has enabled us to biopsy and resect small intraventricular tumours with potentially reduced morbidity. Nevertheless, suitable methods/ instrumentation for resection have limited the use of the endoscope. The authors report the utilisation of endoscopic ultrasonic aspirator in the resection of an intraventricular tumour. This technique was compared to another case that utilised conventional endoscopic techniques for removal of an intraventricular tumour...

Neuroendocrine neoplasms (NEN) occur in the entire gastrointestinal tract. The updated classification of the WHO (2010) and current TNM-classification provide a basis for the therapeutic decision and assess the prognosis. Endoscopy and different imaging techniques are important for the localization of the primary tumor as well as local and distant metastases. The most important diagnostic imaging technique is somatostatin receptor scintigraphy. Therapeutic strategy should be discussed within the scope of a multidisciplinary tumor board...

OBJECTIVE: The anterior clinoid process (ACP) is critically related to the clinoidal portion of the internal carotid artery (ICA). The deep location of the ACP makes treatment of vascular and neoplastic lesions related to the ACP challenging. Removal of the ACP is advocated to facilitate treatment of such lesions. However injury to the clinoidal ICA remains a potential and dreadful complication of ACP removal. The aim of this study was to demonstrate an endoscopic assisted technique to perform intradural removal of the ACP via a pterional approach with continuous visualization of the clinoidal ICA...

OBJECTIVE: The goal of the present article was to describe our dissection training system applied to a variety of endoscopic endonasal approaches. It allows one to perform a 3D virtual dissection of the desired approach and to analyze and quantify critical surgical measurements. METHODS: All the human cadaveric heads were dissected at the Laboratory of Surgical Neuro-Anatomy (LSNA) of the University of Barcelona (Spain). The model surgical training protocol was designed as follows: 1) virtual dissection of the selected approach using our dissection training 3D model; 2) preliminary exploration of each specimen using a second 3D model based on a preoperative computed tomographic scan; 3) cadaveric anatomic dissection with the aid of a neuronavigation system; and 4) quantification and analysis of the collected data...

BACKGROUND: The most dramatic complication in endonasal surgery is inadvertent injury to the internal carotid artery (ICA) with massive bleeding. Nasal packing is the favored technique for control; however, this often causes complete carotid occlusion or carotid stenosis, contributing to the morbidity and mortality of the patient. The aim of this study is to compare the efficacy of endoscopically applied hemostatic techniques that maintain vascular flow in an animal model of carotid artery injury...
