Associations between Toll-like receptor 4 Asp299Gly polymorphism and susceptibility to intracranial aneurysm among male and female patients within the North Indian population.

Objectives: Intracranial aneurysms (IA), often remain asymptomatic until they get ruptured, invariably leads to subarachnoid hemorrhage (SAH), and is influenced by both genetic and environmental factors. Recent studies indicated inflammation as a key player in IA development. This study delves into genetic variations within inflammatory pathways, focusing on TLR4-mediated cytokine release as potential IA biomarkers.

Under recognized yet a clinically relevant impact of aneurysm location in Distal Anterior Cerebral Artery (DACA) aneurysms: insights from a contemporary surgical experience.

Aneurysms of the distal anterior cerebral artery (DACA) are rare but surgically challenging. Despite a known therapeutic implication of the aneurysm location on the DACA territory, the literature is unclear about its clinical and prognostic significance. Our surgical experience over the last 5 years was reviewed to compare the clinical, operative, and outcome characteristics between aneurysms located below the mid portion of the genu of the corpus callosum (called proximal aneurysms) to those distal to this point (called distal aneurysms).

Optimum Surgical Strategies for Medial Sphenoid Wing Meningiomas: A Comprehensive Evaluation of Resection Extent, Visual Outcomes, and Vascular Injury.

Background/objective: Visual impairment affects 55%-80% of medial sphenoid wing meningiomas (mSWMs) patients, making optic nerve decompression a critical surgical goal. Complete resection often leads to better visual outcomes. However, involvement of critical neurovascular structures increases postoperative morbidity and mortality, with vascular injury reported in 18%-20% of cases.

Clipping of Kissing Distal Anterior Cerebral Artery Aneurysms: The Importance of Microsurgical Techniques to Enlarge the Surgical Corridor and Prevent a Premature Aneurysm Rupture.

Intracranial kissing aneurysms, arising either from the same artery or from 2 adjacent arteries at similar locations, are rare. The internal carotid artery is most frequently involved; kissing aneurysms rarely affect the distal anterior cerebral artery (DACA). By dint of the close proximity of the aneurysm fundus, these aneurysms can pose unique operative challenges.

Trans-temporal trans-choroidal resection of thalamic and thalamopeduncular tumors: how I do it.

Background:  Surgical resection is the cornerstone of treatment for low-grade tumors, albeit total excision is beneficial. As the thalamus is surrounded by vital neurovascular system, lesions here present a surgical challenge.

Method: This article aims to demonstrate the trans-temporal, trans-choroidal fissure approach's effective surgical therapy on patients with thalamic lesions.

Occipital encephalocele: a retrospective analysis and assessment of post-surgical neurodevelopmental outcome.

Background: Encephalocele represent a group of disorders which is characterised by extracranial herniation of the leptomeninges, brain, and CSF through a structural defect in the cranium. They are usually associated with other intracranial anomalies which may impact the neurological development.

Aim: This study aimed to assess the predictors of neurological development of patients undergone surgical excision of occipital encephalocele.

Anterior clinoidectomy in low lying internal carotid artery-posterior communicating artery aneurysm.

Background: At times, a regulation internal carotid artery-posterior communicating artery junction (ICA-P-Comm) aneurysm becomes a surgical hurdle owing to its close proximity to the anterior clinoid process, an immovable ICA and a concealed dominant P-Comm artery arising from the aneurysm neck.

Method: A 70 year old patient with a low lying ICA-P-Comm aneurysm underwent a "tailored" intradural clinoidectomy for aneurysm clipping.

Conclusion: A tailored anterior clinoidectomy to expose "just enough" allows a proximal ICA control in a suitable area, mobility of an atherosclerotic ICA and exposes the P-Comm artery origin which are essential in safe clipping of these aneurysms.

Endoscopic MIS-TLIF with Destandau's system: leveraging endoscopy with conventional instruments.

This presentation showcases an endoscopic minimally invasive spine surgery (MISS) technique for lumbar interbody fusion. Significantly expanding the scope of Destandau's system within MISS, it serves as a pivotal link to unilateral biportal endoscopy (UBE) for endofusion. The method involves minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) using a 4-mm rigid endoscope through Destandau's system.

Stereotactic biopsy for brain lesions: Doing more with less.

Objectives: Stereotactic biopsy (STB) is a potential diagnostic tool considering its minimal invasiveness, high diagnostic yield, and minimal associated complications. Over the years, various frame-based instrument systems and frameless stereotactic biopsy systems have emerged to be employed in clinical use. With this study, we intend to get more by doing less in the form of STB for the patients of doubtful intracranial lesions treated over the past 5 years.

Clinicoradiologic Risk Stratification and Outcome Assessment in Symptomatic Intracranial Arachnoid Cyst Managed Over Fifteen Years.

Background: Arachnoid cysts (ACs) are developmental anomalies formed by splitting the arachnoid membrane's layers. ACs contribute around 2% of all intracranial space-occupying lesions. ACs are more prevalent in children.

An Institutional Experience and Literature Review on Iatrogenic Major Vascular Injury in Neurosurgery: Proposal of a Management Algorithm.

Background: Major vessel injury is among the most dreaded complications of any neurosurgical procedure. Once intraoperatively tamponaded, it can present in the form of pseudoaneurysm, dissecting aneurysm or complete occlusion of vessel. These injuries are often associated with very high morbidity and mortality.

Impact of Postoperative ABG Analysis and ICU Weaning Protocol in Surgical Outcome of Atlanto-Axial Dislocation: It's not the Towering Sail, but the Unseen Wind that Moves the Ship.

Background: The outcome in patients of atlanto-axial dislocation (AAD) depends on multiple factors like preoperative optimization, intraoperative distractio and cord manipulation. Certain unfocussed factors such as respiratory reserve and compensatory acclimatization to hypoxia warrant consideration.

Aims: The purpose of this study is to find the association of postoperative arterial blood gas (ABG) analysis and respiratory reserve in patients of AAD with clinical outcome.

Hybrid Anterior Clinoidectomy in the Clipping of Paraclinoid Aneurysms: Technique, Utility and Case Illustration.

Background: Anterior clinoidectomy for aneurysm clipping is generally performed intradurally. Despite obvious advantages, accidental drill slippage or indirect damage from heat and bone dust remain major drawbacks.

Objective: To demonstrate the surgical technique and utility of a combined extra- and intra-dural clinoidectomy in the clipping of dorsal wall paraclinoid internal carotid artery aneurysm.

Role of Extradural Clinoidectomy and Trapping in Giant Superior Hypophyseal Artery Aneurysm.

Giant paraclinoid internal carotid artery (ICA) aneurysms are surgically challenging, mainly owing to lack of adequate working space and distortion of the regional anatomy. Anterior clinoidectomy is a vital surgical technique in such cases, allowing optic nerve decompression and exposure of the proximal ICA outside the confines of the arachnoid. While clinoidectomy is generally conducted intradurally, some aneurysms, particularly unruptured and directed medially paraclinoid ICA aneurysms, can allow a completely extradural clinoidectomy.
