Carotid cavernous fistula: A rare but treatable cause of ophthalmoplegia - A case report.

Carotid cavernous fistulas (CCFs) are a rare but debilitating entity that may present with orbital or cerebral venous hypertension. CCFs may pose diagnostic and management pitfalls for clinicians as they can initially be misdiagnosed as primary orbital pathology or nonarteriovenous shunting-related cavernous sinus pathology. Furthermore, the resolution of pulsatile tinnitus could be an ominous sign in patients with untreated dural arteriovenous fistula.

Outcomes of Particle versus Liquid Embolic Materials Used in Middle Meningeal Artery Embolization for the Treatment of Chronic Subdural Hematoma.

Background: Early evidence suggests that middle meningeal artery (MMA) embolization is an efficacious minimally invasive neuroendovascular technique for the management of chronic subdural hematoma (cSDH). Particle and liquid embolic materials are commonly used to embolize the MMA; however, studies comparing the safety and outcomes between these 2 materials are limited.

Methods: Patients ≥18 years old who had MMA embolization for cSDH between July 15, 2020 and May 1, 2022 were retrospectively identified from a single-center database.

Middle Meningeal Artery Embolization for Primary Treatment of a Chronic Subdural Hematoma in a Pediatric Patient: A Systematic Review of the Literature and Case Report.

Background: Middle meningeal artery (MMA) embolization is becoming increasingly studied as a safe, effective treatment for chronic subdural hematoma (cSDH) in adults. Among pediatric patients, however, MMA embolization for cSDH has been rarely described, and the potential benefit of this approach for pediatric patients remains unknown.

Objective: To systematically review the literature and identify cases of pediatric MMA embolization for cSDH.

Use of reverse angle guide catheter with trans-radial approach in patients undergoing middle meningeal artery embolization.

Background: Trans-radial access (TRA) for MMA embolization has grown due to lower access site complications and greater patient satisfaction. Here, we describe the feasibility of utilizing a 6F Envoy Simmons 2 (6F-SIM2) as a guide catheter with TRA and compare outcomes with trans-femoral approach (TFA) in a single center case series.

Methods: We performed a retrospective review of patients who underwent MMA embolization for management of chronic subdural hematoma (cSDH).

Clot composition of embolic strokes of undetermined source: a feasibility study.

Background: A number of emerging studies have evaluated clot composition in acute ischemic stroke. Studies of clot composition of embolic strokes of undetermined strokes are lacking.

Objectives: We sought to analyze the RBC to platelet ratios in clots and correlated our findings with stroke etiology.

Trends in hospitalizations and epidemiological characteristics of adults Moyamoya disorder in the United States.

Background And Purpose: There has been an increasing prevalence of Moyamoya disorder (MMD) reported from recent US literature. There is a paucity of data available regarding trends of prevalence and epidemiological factors in the United States. To goal of this study was to test the hypotheses that racial-, sex-specific MMD hospitalizations and epidemiological factors have been increasing in the United States over the last decade.

Trends in Endovascular Treatment of Aneurysmal Subarachnoid Hemorrhages.

Introduction: Aneurysmal subarachnoid hemorrhage (aSAH) accounts for 5% of all strokes; 30-day mortality is as high as 40%. We sought to evaluate outcomes of aSAH patients treated 2004-2014 by endovascular therapy (EVT), to demonstrate associated trends, and to evaluate angioplasty use for aSAH-related cerebral vasospasm.

Methods: The Nationwide Inpatient Sample (NIS) database 2004-2014 was used to derive a study cohort using ICD-9 codes.

Endovascular Treatment of Complex Distal Posterior Cerebral Artery Aneurysms with the Pipeline Embolization Device.

Objective: To assess the safety and efficacy of the Pipeline Embolization Device (PED) for endovascular treatment of complex, distal posterior cerebral artery (PCA) aneurysms.

Methods: We conducted a retrospective review of patients who underwent endovascular treatment of complex PCA aneurysms with PED from November 2012 to December 2015. A total of 4 patients were identified and treated.

Rheumatoid Meningitis: Diagnostic and Therapeutic Observations.

A 75-year-old female with untreated rheumatoid arthritis presented with two weeks of behavioral changes and cognitive decline. A neurologic examination showed severe encephalopathy, brisk reflexes, and bilateral Babinski sign. A contrast-enhanced brain MRI demonstrated right meningeal enhancement and periventricular white matter disease.

A Novel Use of Direct Platelet Application During Surgery for Clopidogrel-Associated Intracerebral Hemorrhage.

Background: Dual antiplatelet therapy is associated with increased rates of intracerebral hemorrhage, especially in the context of subarachnoid hemorrhage. We present a case of a spontaneous hemorrhage in a patient treated with a Pipeline stent for a ruptured dissecting vertebrobasilar aneurysm and the novel use of direct application of platelets during surgery to control bleeding.

Case Description: A 54-year-old previously healthy woman presented with an intradural right vertebral artery dissection with a ruptured 6-mm pseudoaneurysm.

Novel application of 3-dimensional rotational C-arm conebeam computed tomography angiography for metastatic hypervascular tumor mass in the spine.

Study Design: This is a case report.

Objective: To report a 3-dimensional (3D) rotational C-arm conebeam computed tomography (CT) (DynaCT) angiography generating computed tomographic data concurrently with spinal angiographic datasets. This technology allowed 3D modeling of the anterior spinal arterial supply in juxtaposition to a hypervascular tumor mass, thus affording unprecedented guidance in presurgical planning.

Percutaneous endoscopic gastrostomy tube placement in left versus right middle cerebral artery stroke: effects of laterality.

Background: Prolonged dysphagia after middle cerebral artery (MCA) territory strokes may require percutaneous endoscopic gastrostomy (PEG) tube feeding.

Objective: We examined the predictors of PEG placement among patients with MCA stroke. It was hypothesized that stroke laterality was a predictor.
