Review Case Reports
Endoneurosurgical resection of intraventricular and intraparenchymal lesions using the port technique.
Deep-seated intraventricular and intraparenchymal lesions have traditionally been resected via transcortical routes, often requiring the use of retractors to maintain the corridor created to reach the lesion and proceed with a bimanual microsurgical resection. A transparent cylindrical conduit (port) has been developed to resect deep-seated lesions using the endoscope or, more recently, Video Telescopic Operating Microscopy (VTOM) for visualization. We describe the surgical technique of the port technique and discuss the evolution of the concept of intraaxial brain surgery performed through a conduit. ⋯ The port technique is an option for resection of intraventricular and intraparenchymal lesions. Additional studies are required to assess its impact on adjacent cerebral tissue morphology, blood flow, and metabolism. Quality-of-life assessments are also needed. High-definition fiber tracking, new visualization techniques (VTOM), and new instrumentation will add to the progress of endoscopic port surgery. We have already seen a significant evolution of the technology even since the preparation of this article.

This study sought to review the articles published by Iranian neurosurgeons regarding their experiences during the Iraq-Iran conflict and compare them with reports from other conflicts. ⋯ Conservative minimal debridement of the wounds is indicated in patients with small entrance wounds, or those with Glasgow Coma Scale score ≥ 8 and no progressive neurological deficit. To diagnose TA before rupture, angiography is indicated in patients who have shells or bone fragments pass through the crowded vasculature, or have large/delayed hematoma, or if the surgeon has high index of suspicion based on neuroimaging and early debridement surgery. Surgery in a well-equipped nearby hospital after quick and safe evacuation of the victims by trained salvaging ancillary groups and the administration of broad-spectrum antibiotics and proper antiepileptics decrease the morbidity and mortality of casualties after PHW in war situations. The biases of the case selection, data collection, and confounders, and decreasing biases by conducting blinded controlled clinical trials, are discussed.

Interhemispheric and quadrigeminal cysts are rare lesions, similar in their propensity to present in young babies and to be associated with other central nervous system malformations, such as corpus callosum agenesia, holoprosencephaly, encephalocele, and neuronal heterotopias. Recently endoscopy has become increasingly popular in the treatment of arachnoid cysts, but experience with cysts located in the interhemispheric fissure and in the quadrigeminal cistern is limited. ⋯ Endoscopic treatment should be considered the first-line option in the treatment of such lesions, even if some complications, such as subdural collections due to thinness of the cerebral mantle or subcutaneous CSF collections due to multifactorial associated hydrocephalus, must be expected.

Intraventricular cystic tumors constitute a surgical challenge, because of their deep location and the histologically benign nature of most of them. We aim to present concisely, yet comprehensively, the role of neuroendoscopy in the treatment of intraventricular cystic tumors. ⋯ Intraventricular endoscopy has emerged as a viable option in the treatment of intraventricular cystic tumors.

To report the efficacy, safety, and outcomes through time of the biggest series to our knowledge of pituitary surgery using transcranial, transsphenoidal, and endoscopic techniques. ⋯ The sum of this 38-year experience of managing pituitary pathology and its surgical treatment shows the importance of working together with other specialists such as endocrinologists, ophthalmologists, and radiologists. The correct treatment approach for each case must be individually selected. Transsphenoidal surgery is an effective and safe treatment for most patients with pituitary adenoma and could be considered the first-choice therapy in all cases except for prolactinomas that respond to pharmacologic therapy (dopamine agonist).
