[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 …

[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 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. […

[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…

[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…

[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 AND OBJECTIVES] Arteriovenous fistulas involving the deep venous system have often been treated with microsurgery or transarterial embolization. Increasing familiarity with transvenous navigation and improved endovascular access…

[BACKGROUND] The incidence of mortality after treatment of unruptured intracranial aneurysms (UIAs) has been described historically. However, many advances in microsurgical treatment have since emerged, and most available data are outdated.…

[BACKGROUND] Basilar artery (BA) fenestration aneurysm (BAFA) is a rare phenomenon commonly accompanying other aneurysms. Treatment is challenging, and few cases have been reported. This review investigated the management outcomes of BAFAs.…

Despite advances in endovascular techniques, microsurgery continues to play an important role in the treatment of cerebral aneurysms. This article reviews the history of surgical treatment of intracranial aneurysms and the evolving role of …

[BACKGROUND] Nationwide study results have suggested varying trends in the incidence of aneurysmal subarachnoid hemorrhage (aSAH) over time. Herein, trends over time for aSAH treated at a quaternary care center are compared with low-volume …

[OBJECTIVE] The Barrow Ruptured Aneurysm Trial (BRAT) was a single-center trial that compared endovascular coiling to microsurgical clipping in patients treated for aneurysmal subarachnoid hemorrhage (aSAH). However, because patients in the…

[OBJECTIVE] Vertebrobasilar dissecting (VBD) aneurysms are rare, and patients with these aneurysms often present with thromboembolic infarcts or subarachnoid hemorrhage (SAH). The morphological nature of VBD aneurysms often precludes conven…

[BACKGROUND] In specialized neurosurgical centers, open microsurgery is routinely performed for aneurysmal subarachnoid hemorrhage (aSAH). [OBJECTIVE] To compare the cost of endovascular vs microsurgical treatment for aSAH at a single quat…

[BACKGROUND] Use of the far lateral transcondylar (FL) approach and vagoaccessory triangle is the standard exposure for clipping most posterior inferior cerebellar artery (PICA) aneurysms. However, a distal PICA origin or high-lying vertebr…

[BACKGROUND] The modified Spetzler-Martin (SM) grading system proposes that grade III arteriovenous malformation (AVM) subtypes are associated with variable microsurgical risks, with small AVMs (III-) having lower risk and medium/eloquent A…

Dissecting fusiform posterior inferior cerebellar artery (PICA) aneurysms are rare and challenging.1,2 One common treatment is occlusion of the aneurysm and parent artery via an endovascular approach without revascularization.3 Revasculariz…

[BACKGROUND] Outcomes for octogenarians and nonagenarians after an aneurysmal subarachnoid hemorrhage (aSAH) are particularly ominous, with mortality rates well above 50%. The present analysis examines the neurologic outcomes of patients ≥ …

The retrosigmoid approach is one of the main approaches used in the surgical management of pontine cavernous malformations. It definitely provides a lateral route to large central lesions but also makes possible resection of some ventral le…
