Background and Aim: The insertion of Ventriculoperitoneal (VP) or Ventriculoatrial (VA) shunt is the first line of treatment in patients with hydrocephalus and normal-pressure hydrocephalus. The provision of a safety profile for shunting in the treatment of hydrocephalus patients is very important. This study aimed to determine the success rates and complications of VP and VA shunting in patients with hydrocephalus. Methods and Materials/Patients: This systematic review investigated the complication rates of VP and VA shunting in managing patients with hydrocephalus. All the published studies were searched in three electronic databases of Web of Science, PubMed and Google Scholar from March 20 to April 10, 2020, using the keywords of “ Ventriculoperitoneal” and “ Ventriculoatrial” in combination with “ Hydrocephalus” . Results: In total, nine articles met the eligibility criteria for being included in this review. Some studies showed a higher rate of shunt obstruction in patients undergoing VA shunting; however, other studies demonstrated no difference in terms of shunt obstruction. The rates of primary revision shunt were various within the ranges of 5. 4%-48% and 9. 1%-58% for VA and VP shunting, respectively. A higher rate of revision shunt was reported among the patients undergoing VP shunting, compared to that reported for VA shunting. The different mortality rates in various studies were estimated within the range of 0%-10% and at 13. 9% for VA and VP shunting, respectively. Conclusion: In general, no difference was reported between VA and VP shunting regarding the rates of complications and mortality. Due to the ease of placement and revision, VP shunting could be considered the first-line treatment of hydrocephalus. However, this approach has been preferred in newborns, and there have been insufficient data on adults in this regard.

Background and Aim: EETA (Endoscopic Endonasal Transsphenoidal Approach) is a preferred choice for pituitary tumors. EETA offers minimal invasiveness, fewer complications, and better outcomes than the sublabial or transseptal microscopic approach. EETA has three approaches: mononostril endoscopic transsphenoidal approach, binostril endoscopic transsphenoidal approach, and one and a half nostril approach. This study aims to compare three different EETAs and compare between microscopic transsphenoidal approach, transcranial approach and EETA. Methods and Materials/Patients: To provide up-to-date information, we concisely reviewed these three EETAs. Using the keywords of “ neuroendoscopy” , “ META” (Mononostril Endoscopic Transsphenoidal Approach), “ OETA” (One and a half nostril Approach), “ BETA” (Binostril Endoscopic Transsphenoidal Approach), “ pituitary adenoma” , “ EETA” , “ endoscopy” , “ transsphenoidal approach” , “ transcranial approach for pituitary adenoma” and “ microscopic transsphenoidal approach” . We retrieved all the relevant articles from Google Scholar, PubMed, and Medline. Then, we reviewed them and critically analyzed them. Results: In BETA there is free and easy movement of surgical instruments in the surgical field and a broader view of the sphenoid sinus and it is an excellent approach to resect large tumors. The META is suitable in tumors with limited involvement of the intra-sellar and supra-sellar area. The mononostril approach is not suitable and has some limitations for the following situations: a crowded narrow nasal cavity, a harder tumor with the invasive appearance or significant suprasellar extension, and lesions other than pituitary adenomas. The OETA provides a sufficient surgical corridor for a 2-surgeon/4 or 3-hands technique with a minimal injury of the nose and good operative results, free and easy movement of surgical instruments in the surgical field, low postoperative morbidity, and good post-operative quality of life. Conclusion: In EETA, knowing the size and consistency of tumor, general versus invasive pituitary adenoma, and the extent of parasellar and suprasellar extension, is essential. If we cannot reach a pituitary macroadenoma with a trans-sphenoidal approach, then we can use a transcranial approach for the removal of the tumor. The microscopic transsphenoidal approach is suitable for pediatric pituitary adenoma.

Background and Aim: The present study aimed to use the median nerve Compound Muscle Action Potential (CMAP) amplitude by stimulation at the palm instead of Abductor Pollicis Brevis (APB) needle Electromyography (EMG) for determining axonal loss in patients with Carpal Tunnel Syndrome (CTS). Methods and Materials/Patients: This study was performed on 180 patients with CTS referred to the Electrodiagnostic (EDX) Center, Poursina Hospital, Guilan Province, Iran, in 2018-19. In this study, the APB needle EMG diagnostic test was used as the gold standard, and median nerve CMAP amplitude with stimulation at the palm and wrist were used to compare the two nerve stimulation tests. Results: All of the cases with abnormal amplitude loss detected by median nerve stimulation at the palm also had an axonal loss in the needle EMG of APB. So this test could be a good indicator of axonal loss if there is an abnormality (sensitivity: 73%, specificity: 100%). The results with wrist stimulation were not as accurate as of the palm stimulation, and some cases with decreased CMAP amplitude of median nerve had normal needle EMG of APB muscle (sensitivity: 86. 6%, specificity: 94. 9%). Conclusion: In cases with CTS, the abnormally decreased amplitude of the median nerve detected by stimulation at the palm could be a good indicator of axonal loss.

Background and Aim: Indocyanine Green (ICG) angiography has become the standard of practice in many centers managing cerebrovascular diseases. Though 3D stereoscopic recording of the surgeries has received widespread attention, there is a need for a technology to display and record real-time 3D ICG angiographies. In this study, we designed and constructed an ICG angiography camera to display the real-time 3D ICG angiographies. Methods and Materials/Patients: Our project had three phases. In phase I, a handmade ICG camera was designed and constructed in our laboratory. The second phase included creating a 3D camera to display real-time images in 3D anaglyph format. In the last phase, we developed a 3D ICG camera to demonstrate 3D ICG angiographies in real-time. Results: We successfully completed all three phases of the project and could display real-time 3D ICG angiography of a mouse mesenteric arteries, recorded it, and took pictures. Conclusion: We proposed a method and proved its feasibility for producing a 3D ICG angiography camera to be mounted on the next generation of neurosurgical microscopes.

Background and Aim: Gynecological cancer is one of the most common types of cancer worldwide. Nonetheless, spinal metastasis from gynecological cancer is scarcely reported in the literature. In cases of spinal cord compression, the standard treatment is a decompressive surgery followed by radiotherapy treatment for selected patients. This study aimed to report the overall survival and surgical results in patients presenting with gynecological spinal metastases who underwent spinal cord/nerve root decompression and stabilization. Methods and Materials/Patients: A total of 18 patients were included in this study. The surgical procedures were performed from 2012 to 2019. The evaluation of neurological status, spinal stability, and pain were performed using the American Spinal Injury Association Impairment Scale (ASIA), Spinal Instability Neoplastic Score (SINS), and Visual Analogue Scale (VAS), respectively. Results: The lumbar spine was the most affected location (n=30; 50. 0%). Regarding the preoperative neurological deficits, 16 cases (n=16; 88. 9%) presented ASIA graded A– D before the surgery, being reduced to five (n=5; 27. 8%) after the procedures. The pain level means (pre-and postoperative) were 9. 39± 0. 79 and 2. 28± 1. 44. The overall median survival was 6. 1 months (95% Confidence Interval [CI] of 1. 10– 11. 13 months). The mean survival of ambulatory and non-ambulatory patients before the surgery was 7. 36 months and 3. 2 months, respectively (P=0. 007 – Log-rank Mantel– Cox). Conclusion: Decompressive surgery and stabilization promote mechanical pain relief, spinal stability, an improvement of neurological function, and indirectly improving quality of life, despite a dismal overall survival of patients who present with metastatic spinal compression disease.

Background and Aim: Most good grade (WFNS I and II) patients who undergo microsurgical clipping achieve a favorable outcome. However, some independent patients before surgery face unfavorable outcomes after the operation, signifying the impact of microsurgical clipping. This study aimed to identify the risk of developing dependency in patients without previous neurological deficits. Methods and Materials/Patients: We reviewed 50 consecutive good grade patients with ruptured anterior circulation aneurysms who underwent microsurgical clipping between May 2017 and May 2020 in the Department of Neurosurgery, Punjab Institute of Neurosciences, Lahore, Pakistan. The clinical outcome at discharge and three months follow-up was assessed using the Glasgow Outcome Scale (GOS). Results: In this study, seven patients (14%) became dependent (GOS II and III) following clipping. Of whom, five patients (10%) suffered surgical insult in the form of intraoperative rupture (4%), post-op infarct (4%), and direct brain damage (2%). Conclusion: Patients without neurologic deficit pre-operatively still suffer unfavorable outcomes mainly due to operative complications. Vascular injuries remain the main cause of morbidityproducing dependency. Therefore, all surgical techniques must minimize the risk to vessels, both during dissection and at clip placement.

Background and Importance: SARS-CoV-2 virus causes COVID-19. The virus’ s primary target is the respiratory system, but it can also affect other systems, such as the cardiovascular and the central nervous system. Case Presentation: In this study, we introduce an 83-year-old man who was referred due to a reduced level of consciousness and hemiparesis in the left part of his body without symptoms such as fever, cough, muscle aches, and fatigue. In High-Resolution Computed Tomography (HRCT) of the lung, the Ground-Glass Opacification/Opacity (GGO) view indicated COVID-19 disease, and in Computerized Tomography (CT) scans of the brain, hemorrhage was evident in the right thalamus, lateral and right ventricle. The Polymerase Chain Reaction (PCR) test performed on the upper part of the nose was also positive. This research is a case report of intracranial and intraventricular hemorrhage in an aged man with asymptomatic COVID-19. Conclusion: Low level of consciousness in the elderly can be a sign of infection with the SARSCoV-2 virus.

Background and Importance: Transorbitocranial assaults with sharp objects like a knife are rare neuro-ophthalmologic emergencies. However, they can have dramatic functional and life-threatening consequences. Our presentation aims to report the importance of an urgent multidisciplinary approach and to raise awareness among the general population on the importance of preventing violent behavior. Case Presentation: A 33-year-old man was a victim of a knife attack without obvious brain or ophthalmological lesions. The knife entered the medial part of the orbit. Neurological examination was normal, and Computed Tomography (CT) scan showed intracranial trajectory through the orbit to the frontal horn of the lateral ventricle. The knife was extracted without complications. The patient reported spectacular improvement in visual acuity without neurological or oculomotor deficit at long-term follow-up. In this case report, we will discuss the radiological diagnosis and surgical management of transorbital and orbitocranial injuries by foreign body penetration. Conclusion: Urgent multidisciplinary management in orbitocranial trauma by stabbing is mandatory to avoid life-threatening complications and irreversible damages.
