Endoscopic third ventriculostomy in children: problems and surgical outcome: analysis of 34 cases.

Background: Endoscopic third ventriculostomy (ETV) has been established as a viable treatment option for obstructive hydrocephalus of children over 6 weeks of age. ETV in pediatric groups may be unsuccessful due to the failure of absorption of cerebrospinal fluid (CSF) or reclosure of ventriculostomy stoma or due to infection. The exact cause is still debatable.

Nonmissile Penetrating Injury to the Head: Experience with 17 Cases.

Background: Penetrating nonmissile injuries to the head are far less common than missile penetrating injuries. Here we describe our experience in managing 17 cases of nonmissile injury to the head, likely the largest such series reported to date. We also highlight the surgical steps and techniques used to remove in situ objects (including weapons) in the penetrating wounds that have not been described previously.

Intracranial nonvestibular neurinomas: Young neurosurgeons' experience.

Background And Objectives: Neurinoma arising from other than nonvestibular cranial nerves is less prevalent. Here we present our experiences regarding the clinical profile, investigations, microneurosurgical management, and the outcome of nonvestibular cranial nerve neurinomas.

Materials And Methods: From January 2005 to December 2011, the recorded documents of operated nonvestibular intracranial neurinomas were retrospectively studied for clinical profile, investigations, microneurosurgical management, complications, follow-up, and outcomes.

High cervical spinal schwannoma; microneurosurgical management: an experience of 15 cases.

Purpose: Schwannoma arising from high cervical spinal root are common among the spinal schwannomas.Here, we prospectively recorded the clinical features, radiological features, surgical approaches & findings,postoperative follow up & ultimate neurological outcome of high cervical spinal schwannomas and then we evaluated the records retrospectively.

Method: Here, schwannomas arising from C1, C2 and C3 spinal nerve roots were regarded as high cervical spinal schwannoma.

Surgical management of scalp arterio-venous malformation and scalp venous malformation: An experience of eleven cases.

Aims: Scalp arterio-venous malformation (AVM) and scalp venous malformation (SVM) are rare conditions that usually need surgical treatment. Here, we have reported our experience of the surgical management of such lesions with a short review of the literature.

Materials And Methods: In this prospective study, 11 patients with scalp AVM and SVM, who underwent surgical excision of lesion in our hospital from 2006 to 2012, were included.

Intracranial epidermoid tumor; microneurosurgical management: An experience of 23 cases.

Objectives: An intracranial epidermoid tumor is relatively a rare tumor, accounting for approximately 0.1% of all intracranial space occupying lesions. These are also known as pearly tumor due to their pearl like appearance.

Endoscopic endonasal transsphenoidal exposure of circle of Willis (CW); can it be applied in vascular neurosurgery in the near future? A cadaveric study of 26 cases.

Aim: Endonasal transsphenoidal approaches are getting rapidly popular in removing many midline skullbase lesions from crista galli to foramen magnum. For safe removal of these lesions, familiarity with endoscopic endonasal anatomy of circle of Willis is very important. Furthermore, for safe development of this approach in vascular neurosurgery in the near future, endoscopic endonasal exposure of circle of Willis is a fundamental step.

Pathological findings in cystic craniopharyngiomas after stereotactic intracavitary irradiation with yttrium-90 isotope.

Histopathological, ultrastructural and polyacrylamide gel electrophoretic examinations were carried out on biopsy, cyst fluid, surgical pathology and autopsy specimens obtained from 7 cystic craniopharyngioma cases before and after yttrium-90 silicate colloid (90Y) irradiation. Light microscopy revealed that the lining epithelial tumor cell layer of the cyst wall was destroyed, and scar tissue containing large amount of hyaline degenerated collagen bundles replaced it. Proliferative postirradiation vasculopathy was also demonstrated in the cyst wall following 90Y installation.
