[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…

[INTRODUCTION] Cerebrovascular bypass surgery is technically demanding, with dozens of modifiable parameters influencing operative decision-making. Thoughtful selection of needle and suture materials is critical to success in these operatio…

[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] 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…

Spetzler-Martin Grade IV arteriovenous malformations (AVMs) are challenging due to high risks associated with both treatment and natural progression. This study compares the outcomes of microsurgical resection and stereotactic radiosurgery …

[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] Patient outcomes in medicine vary significantly when stratified by socioeconomic status (SES). In the cerebrovascular area specifically, rates of treatment of intracranial aneurysms (IAs) and overall outcomes after subarachnoid …

[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…

Posterior cerebral artery aneurysms are rare and often optimally treated with clip reconstruction. Complex cases may require aneurysm excision with in situ reanastomosis. A woman in her early 40s presented with 2 weeks of severe headache an…

[BACKGROUND AND IMPORTANCE] Complex cerebrovascular bypass operations may confer an increased risk of intraoperative complications, such as graft thrombosis. Novel techniques are needed to optimize the management of these challenging cases.…

[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] 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.…

[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 …

[BACKGROUND] New findings and research regarding the microsurgical treatment of intracerebral aneurysms (IAs) continue to advance even in the era of endovascular therapies. Research in the past 2 decades has continued to revolve around the …

[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] 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…

[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 ≥ …

Fibrin glue injection within the cavernous sinus (CS) is a demonstrably safe and simple technique to control venous bleeding with a low complication rate. However, this technique does have inherent risks. We illustrate 2 cases of internal c…
