Endoscopic evacuation of septated chronic subdural hemorrhage - Technical considerations, results, and outcome.

Background: Chronic subdural hematoma (cSDH) is a common entity in the elderly. Homogeneous or well-liquefied CSDH has a standard line of treatment through burr hole and irrigation. However, the management of septated chronic subdural hematoma (sCSDH) with multiple membranes does not have a well-defined surgical approach.

External ventricular drain related complications-whether continuous csf drainage via ommaya reservoir is the answer?

Background And Aims: External ventricular drainage (EVD) is one of the commonest procedures in neurosurgical practice to manage acute hydrocephalus. We evaluated the infectious and non-infectious complications associated with a modified technique for EVD using an Ommaya reservoir.

Methods: Ommaya reservoir was placed in all patients who required EVD placement for CSF drainage.

A Rare Case of Simultaneous Multifocal Craniospinal Hemangiopericytomas.

First reported case of simultaneous occurrence of hemangiopericytomas(HCP) at multiple sites of craniospinal axis in a thirty four year male is presented. Patient presented with neck pain for 1 year, and one episode of simple partial seizure involving his left lower limb. He was diagnosed as having HCP in right middle one third parasagittal region, and C4,5 vertebral bodies.

Syringe Port: A Convenient, Safe, and Cost-Effective Tubular Retractor for Transportal Removal of Deep-Seated Lesions of the Brain.

Objective: Minimally invasive transportal resection of deep intracranial lesions has become a widely accepted surgical technique. Many disposable, mountable port systems are available in the market for this purpose, like the ViewSite Brain Access System. The objective of this study was to find a cost-effective substitute for these systems.

Lateral ventricular gliosarcoma with attachment to septum pellucidum.

Gliosarcomas are lesions with both glial and sarcomatous elements and are usually seen abutting the dura. Intraventricular location is extremely rare. Such an unusual intraventricular gliosarcoma is being reported.

Application of a Far-Lateral Approach to the Subaxial Spine: Application, Technical Difficulties, and Results.

Objective: The far-lateral approach has traditionally been used as an approach to ventral foramen magnum pathologies. Ventral pathologies in the cervical spine and cervicodorsal regions also provide unique surgical challenges. Traditional posterior surgical approaches to the ventral cervical pathologies require significant cord retraction, and anterior approaches require significant bone removal with implant stabilization.

Types of Azygos Distal Anterior Cerebral Artery Branching Patterns: Relevance in Aneurysmal Surgery.

Azygos distal anterior cerebral artery (Az.DACA) is a rare anatomical variant. This variant has been found to be associated with aneurysms in a significant proportion of patients.

Serum lipid profile spectrum and delayed cerebral ischemia following subarachnoid hemorrhage: Is there a relation?

Background: Serum lipid abnormalities are known to be important risk factors for vascular disorders. However, their role in delayed cerebral ischemia (DCI), the major cause of morbidity after subarachnoid hemorrhage (SAH) remains unclear. This study was an attempt to evaluate the spectrum of lipid profile changes in SAH compared to matched controls, and their relation with the occurrence of DCI.

Prospective study of the correlation between admission plasma homocysteine levels and neurological outcome following subarachnoid hemorrhage: a case for the reverse epidemiology paradox?

Background: Homocysteine (tHcy) has been known over the last few decades for its putative impact on vascular diseases, but has not been evaluated much in patients with subarachnoid hemorrhage (SAH). This study was carried out to assess its prognostic impact on the neurological outcome following SAH.

Methods: Admission plasma tHcy was evaluated in 90 SAH patients and prospectively studied in relation to various factors and the Glasgow Outcome Scale (GOS) at 3 months.

Marker-CT assisted surgery using household key ring: A simple substitute to frameless stereotaxy for developing countries.

Background: Operative localization systems such as stereotactic frames and neuronavigation are prohibitively expensive to be of use in many centers in developing countries. Here, we present a modified version of marker-computed tomography (CT) assisted technique using a household key ring, which can be performed in any operative set-up lacking modern amenities.

Case Description: For a patient who presents with left posterior frontal lesion, the approximate entry point for the shortest and perpendicular trajectory to the lesion is marked on the scalp using a household key ring and fixed in place.

Vasospasm following aneurysmal subarachnoid hemorrhage: Thrombocytopenia a marker.

Background: Symptomatic vasospasm (SV) is often seen after aneurysmal subarachnoid hemorrhage (aSAH). The pathophysiology suggests that platelets initiate the process and are consumed. This is likely to result in thrombocytopenia.

Importance of an intact dura in management of compound elevated fractures; a short series and literature review.

Purpose: To describe compound elevated fractures (CEFs) of the skull vault, with radiological pictures, management problems and prognosticative factors.

Method: The authors describe three cases of CEFs of the cranium, their mode of injury, clinical findings, radiological images and management problems. The authors have reviewed the existing literature regarding epidemiological data, neurological status, dural breech, methods of management and final outcome, in respect of CEFs.
