Safety and efficacy of flow diverter stents in the treatment of bifurcation cerebral aneurysms: single-center experience.

Purpose: The use of flow diverter (FD) stents is continually expanding. Aneurysms on arterial bifurcation typically have an undesirable anatomical form, are frequently wide-necked, and include one or more side-branch arteries. In recent years, the off-label use of flow diversion in treating intracranial aneurysms beyond the internal carotid artery has become increasingly popular.

A novel intraoperative "Faucet" technique for assessing patency of superficial temporal artery to middle cerebral artery bypass and for prevention of microemboli.

Purpose: This technical note introduces the novel faucet technique, which enables neurosurgeons to evaluate the patency of a bypass during superficial temporal artery-middle cerebral artery bypass surgery. The technique is particularly useful when there is a lack of equipment such as micro-Doppler or indocyanine green in the operating rooms. This is often the case in Central Asian countries.

Study of the stress in adults diagnosed with meningioma: Insights from a tertiary neurosurgical hospital.

Background: Meningiomas are the most common type of primary brain tumor, originating from the meninges - the protective membranes that surround the brain and spinal cord. Several well-studied risk factors for meningiomas include gender, age, radiation exposure, genetic factors, and hormonal factors. Moreover, the influence of a person's psycho-emotional stateon their overall health and mental well-being, specifically stress, iscurrently a significant and relevant topic of discussion.

Associations of Brain Arteriovenous Malformation-Related Factors with Epileptic Seizure Presentations.

Background: Arteriovenous malformations (AVMs) are abnormal tangles of arteries and veins that connect directly without an intervening capillary bed. Epileptic seizures are the second most common symptom in patients with brain AVMs, occurring in 30 to 50% of cases. However, the exact mechanism of epileptic seizure development in AVMs remains unclear.

The outcomes of microvascular decompression for primary trigeminal neuralgia: insights from a single-center experience and technical advancements.

Background: Microvascular decompression (MVD) remains the primary surgical treatment for trigeminal neuralgia due to its positive postoperative results. This study aims to evaluate the outcomes of patients with primary trigeminal neuralgia who underwent MVD. Additionally, the paper offers a detailed explanation of the surgical methodology of MVD employed at the neurosurgical hospital in Kazakhstan.

Long-Term Outcomes of Endovascular Embolization in a Vein of Galen Aneurysmal Malformation: A Single-Center Experience.

Background: A vein of Galen aneurysmal malformation (VGAM) is a rare congenital cerebral vascular condition with a high mortality rate if left untreated. This study describes the long-term outcomes of patients with VGAM, who were treated with endovascular embolization.

Methods: This retrospective analysis focused on VGAM patients who underwent one or more endovascular embolization sessions between January 2008 and December 2022.

A case report of multi-step management of extracranial carotid artery aneurysm and carotid-cavernous fistula combination in patients.

Extracranial carotid artery aneurysms (ECAA) and carotid-cavernous fistulas (CCF) are rare arterial pathologies with severe complications and increased risk of mortality. The optimal treatment approach for this combined condition is a topic of debate among neurosurgeons and neuroradiologists, and a standardized treatment protocol has yet to be established. The aim of this case report was to demonstrate the management of a rare combination of ECAA and CCF in patients.

An Uncommon Case of Moyamoya Syndrome Is Accompanied by an Arteriovenous Malformation with the Involvement of Dural Arteries.

(1) Background: This report describes the surgical management of a case of concurrent AVM with the involvement of dural arteries and moyamoya syndrome. Given the infrequency of this combination, there is currently no established management strategy available. (2) Case Description: A 49-year-old male patient with multiple symptoms including headaches, tinnitus, and visual impairment diagnosed with the coexistence of an arteriovenous malformation with the involvement of dural arteries and moyamoya syndrome was admitted to the national tertiary hospital.

Effect of Targeted Embolization on Seizure Outcomes in Patients with Brain Arteriovenous Malformations.

Background: Seizures are one of the most debilitating manifestations of brain arteriovenous malformations (AVMs). This study aimed to evaluate the effect of curative embolization on brain AVM patients presenting with seizures.

Methods: The records of patients who underwent embolization for brain AVM from January 2012 to December 2020 were evaluated and patients presenting with seizures were interviewed.

Whole-Exome Sequencing Reveals Pathogenic SIRT1 Variant in Brain Arteriovenous Malformation: A Case Report.

Arteriovenous malformations of the brain (bAVMs) are plexuses of pathological arteries and veins that lack a normal capillary system between them. Intracranial hemorrhage (hemorrhagic stroke) is the most frequent clinical manifestation of AVM, leading to lethal outcomes that are especially high among children and young people. Recently, high-throughput genome sequencing methods have made a notable contribution to the research progress in this subject.

Management of giant internal carotid aneurysm by extracranial-intracranial bypass and flow diverter stent.

Flow diverter stents have become the standard approach to managing intracranial aneurysms; however, in some cases of complex, wide-necked aneurysms, poor outcomes due to stent occlusion have been reported. We report the case of a giant internal carotid artery aneurysm treated by high-flow extracranial-intracranial (EC-IC) bypass with flow diverter deployment. Seven months post-operatively, radiographic imaging demonstrated occlusion of the stent and parent artery, with further ischemic events prevented by collateral flow from the high flow bypass.
