[OBJECTIVES] Approximately 30% of patients with subarachnoid hemorrhage (SAH) present with multiple aneurysms. Identifying the ruptured aneurysm is often difficult, and not all lesions may be accessible through a single craniotomy. Magnetic…

[BACKGROUND AND OBJECTIVES] Identifying surgical candidates who are prone to poor outcomes is crucial for adapting treatment and ensuring optimal outcomes. Our aim was to use unsupervised machine learning to reveal patient outcome subgroups…

[BACKGROUND AND OBJECTIVES] The optimal management of unruptured intracranial aneurysms (UIAs) remains controversial. Options include observation, endovascular treatment, microsurgical intervention, or a combination. However, clear outcome …

[BACKGROUND] Human immunodeficiency virus (HIV) infection is linked with an uncommon vasculopathy syndrome, increasing the susceptibility of infected individuals to develop aneurysms across systemic vasculature, notably in the cerebral vasc…

[BACKGROUND] Anterior spinal artery (ASA) aneurysms are uncommon and difficult to diagnose due to their variable presentation and limited visibility with traditional imaging. They often present with severe back pain from rupture and spinal …

[OBJECTIVE] Blister aneurysms of the internal carotid artery (ICA) have high associated mortality rates and are challenging due to their friable wall and poorly defined neck. Microsurgical and endovascular treatment options have been sugges…

[BACKGROUND] Brain arteriovenous malformations (AVMs) are abnormal connections between feeding arteries and draining veins, associated with significant risks of haemorrhage, seizures and other neurological deficits. Preoperative embolizatio…

[BACKGROUND AND OBJECTIVES] Arteriovenous malformations (AVMs) with perinidal aneurysms and single draining vein are associated with an elevated risk of rupture and increased procedural complexity. The role of preoperative embolization in t…

[OBJECTIVE] With the increasing number of intracranial aneurysms (IAs) treated by endovascular coiling, more residual and recurrent IAs are being encountered. This study aimed to evaluate the effectiveness and safety of the microsurgical ma…

Cochlear schwannomas are a rare subset of schwannomas arising from the cochlear nerve within the cochlea or internal auditory canal. These tumors can present with posterior displacement of the facial nerve, making facial nerve preservation …

[BACKGROUND AND OBJECTIVES] Controversy exists regarding whether to treat unruptured intracranial aneurysms (UIAs) in older patients. This study analyzes modern outcomes among older patients who underwent microsurgical treatment for UIA. […

[OBJECTIVE] Objective values on procedural risk are essential to facilitate informed consent and optimize clinical decision-making in patients with unruptured intracranial aneurysms (UIAs). While robust heuristics, such as the PHASES (popul…

[INTRODUCTION] Giant intracranial aneurysms are rare vascular lesions consisting of cerebral aneurysms measuring ≥25 mm in diameter. Their formation is the result of multiple factors including their association with a unique genomic landsca…

[BACKGROUND AND OBJECTIVES] Preventive treatment of unruptured intracranial aneurysms (UIAs) requires assessment of treatment risks vs expected benefit. Although established scores exist to estimate rupture and growth risk, currently, no ex…

[OBJECTIVE] The aim of this study was to assess the surgical use and applicability of a biportal bitransorbital approach. Single-portal transorbital and combined transorbital transnasal approaches have been used in clinical practice, but no…

[BACKGROUND] Tridimensional medical knowledge of human anatomy is a key step in the undergraduate and postgraduate medical education, especially in surgical fields. Training simulation before real surgical procedures is necessary to develop…

Brain Arteriovenous Malformations (bAVMs) are rare but high-risk developmental anomalies of the vascular system. Microsurgery through craniotomy is believed to be the mainstay standard treatment for many grades of bAVMs. However, a signific…

Brain arteriovenous malformations (bAVMs) are complex, and rare arteriovenous shunts that present with a wide range of signs and symptoms, with intracerebral hemorrhage being the most severe. Despite prior societal position statements, ther…

[OBJECTIVE] Axel Perneczky is responsible for conceptualizing the "keyhole" philosophy as a new paradigm of minimal invasiveness within cranial neurosurgery. Keyhole neurosurgery aims to limit approach-related traumatization and minimize br…

 Transorbital neuroendoscopic surgery (TONES) has ignited interest in the transorbital access corridor, increasing its use for single and multi-portal skull base interventions. However, the crowding of a small corridor and two-dimensional v…

[OBJECTIVE] Posterior fossa arteriovenous malformations (AVMs) represent 7% to 15% of all intracranial AVMs and are associated with an increased risk of hemorrhage, morbidity, and mortality compared with supratentorial AVMs, thus prompting …

[BACKGROUND] Dural arteriovenous fistulas (dAVFs) located at craniocervical junction are extremely rare (1%-2% of intracranial/spinal dAVFs). Their angio-architectural complexity renders endovascular embolization to be challenging given mul…

[BACKGROUND] Advances in computer sciences, including novel 3-dimensional rendering techniques, have enabled the creation of cloud-based virtual reality (VR) interfaces, making real-time peer-to-peer interaction possible even from remote lo…

There is no systematic review investigating the utility of Diffusion tensor-based tractography findings for treating brain arteriovenous malformations (bAVMs). This systematic review aims to investigate the outcomes following bAVM treatment…
