PURPOSE: Aneurysm recanalization constitutes a limitation in the endovascular treatment of intracranial aneurysms using conventional bare platinum coils. The development of platinum coils coupled with hydrogel polymers aimed at decreasing the rates of recurrence by way of enhanced coil packing density and biological healing within the aneurysm. While enhanced occlusion and durability has been shown for the first generation hydrogel coils, their use was limited by technical challenges...

Early brain injury (EBI) after aneurysmal subarachnoid hemorrhage (SAH) contributes to high morbidity and mortality. Although it is well recognized that acute neuroinflammation reaction is one of the most important triggers of EBI, pharmacotherapy proved to be clinically effective against the initiating of neuroinflammation after SAH is lacking. The resident microglia and infiltrated peripheral monocyte are two main types of immune cells in central nervous system (CNS) and control the inflammation process in brain after SAH...

Bilateral cavernous carotid aneurysms (CCAs) represent a rare medical condition that can mimic other disorders. We present a rare case of bilateral CCAs simulating an ocular myasthenia. A 76-year-old woman presented with a history of fluctuating bilateral diplopia and unilateral ptosis, which led to the suspicion of ocular myasthenia. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the brain showed the presence of large bilateral aneurysms of the carotid cavernous tract. After an unsuccessful attempt with steroid therapy, the patient underwent endovascular treatment, with mild improvement...

Saccular intracranial aneurysm (sIA) rupture is often fatal. Rupture-prone sIA walls are infiltrated by macrophages expressing hemoglobin-receptor CD163, suggesting a role for erythrocyte lysis in the degenerative remodeling predisposing to rupture. We therefore studied erythrocyte remnants in 16 unruptured and 20 ruptured sIA walls using histology and immunohistochemistry. Glycophorin A (GPA), an erythrocyte membrane protein, was present in 34/36 (94%) sIA walls and correlated with loss of αSMA+ cells, reflecting loss of mural smooth muscle cells ([SMCs]; r = -0...

Objective: Aneurysm rupture during in-hospital period contributes to the exceedingly high morbidity and mortality of inpatients with untreated aneurysm. However, risk factors for aneurysm rupture during hospitalization were scarcely focused in previous reports. The aim of this study was to investigate the risk factors of aneurysm rupture during hospitalization and to propose clinical strategies improving prognosis. Methods: Patients with intracranial aneurysm (lA) rupture during hospitalization were identified in our prospective cohort of consecutive patients admitted to Beijing Tiantan Hospital between Jan 2014 to Dec 2017...

BACKGROUND: Previous reports indicated an association between hemorrhagic presentation and flow-related aneurysms in arteriovenous malformation (AVM) patients. However, it remains unclear whether these flow-related aneurysms result in the hemorrhage of AVM. OBJECTIVE: To characterize this hemorrhage risk using our institutional experience over 25 yr. METHODS: We retrospectively reviewed records of patients at our institution diagnosed with AVM from 1990 to 2015...

BACKGROUND: Moyamoya disease (MMD), arterial venous malformations (AVMs), and intracranial aneurysms are distinct cerebrovascular disease processes that most commonly occur in isolation. The literature on the treatment algorithm of each individual condition is well established. An association between MMD and intracranial aneurysms is also known; but MMD in association with AVM is rare. CASE DESCRIPTION: The authors discuss various dilemmas in the multi-modality management of these conditions when they coexist with an illustrative case of a 46-year-old woman who presented following a stroke, with 1) left-sided MMD, 2) left-sided frontal AVM, and 3) an aneurysm arising from A1 segment of right anterior cerebral artery...

Background: Aneurysmal subarachnoid hemorrhage (aSAH) continues to be a devastating neurological condition with a high risk of associated morbidity and mortality. Inflammation has been shown to increase the risk of complications associated with aSAH such as vasospasm and brain injury in animal models and humans. The goal of this review is to discuss the inflammatory mechanisms of aneurysm formation, rupture and vasospasm and explore the role of sex hormones in the inflammatory response to aSAH...

OBJECTIVE: To explore whether computed morphological features can be used as independent predictors of incomplete occlusion of aneurysms treated with pipeline embolization device. METHODS: From January 2016 to September 2017, 58 patients with 58 aneurysms were treated with pipeline embolization device in our center. Aneurysms were manually segmented from the DICOM file and we calculated 16 shape features voxel by voxel on the segmented aneurysm image. Along with other 13 clinical and radiographic variables, we performed univariate and multivariate analysis to explore predictors of incomplete occlusion...

OBJECTIVE: Intracranial aneurysm (IA) is a life threatening cerebrovascular disease characterized by phenotypic modulation of vascular smooth muscle cells (VSMCs) and loss of vessel cells. In addition to environmental factors, genetic factors have been proposed to be a critical factor in the onset and progression of IA. The present study investigates the effects of serine-arginine protein kinase 1 (SRPK1) on VSMC proliferation and apoptosis both in vivo and in vitro, as well as its role in vascular remodeling in vivo through PI3 K/Akt signaling in IA...

BACKGROUND: Bypass surgery for complex intracranial aneurysms (IAs) results in drastic blood flow changes in intracranial arteries. The aim of the study was to elucidate how vessels adapt to blood flow changes after bypass surgery with phase-contrast magnetic resonance imaging (PC-MRI). METHODS: This is a prospective observational study to assess changes of the blood flow in intracranial arteries after bypass surgery for IAs. Flow rates and vessel diameters were measured with PC-MRI in 52 intracranial arteries of 7 healthy volunteers and 31 arteries of 8 IA patients who underwent bypass surgery...

The eyebrow approach is a versatile technique that may apply to various vascular and tumoral pathologies of the anterior skull base. We present a case of multiple aneurysms clipping through the eyebrow approach and we discuss the nuances of this technique. A 44-yr-old patient presented with incidentally found aneurysms. Angiography showed 2 4.5-mm aneurysms on the left middle cerebral artery (MCA) and internal carotid artery (ICA) bifurcations. At surgery, the patient is positioned supine with the head elevated, slightly rotated, and extended in order to obtain good access and gravity retraction of the brain...

Giant brain aneurysms account for approximately 5% of all intracranial aneurysms. Although treatment modalities can vary widely, none is ideal for every patient. Endovascular treatment is usually preferred, especially when the large size of the aneurysm limits visualization of the brain parenchyma and parent vessels that arise from the aneurysm, making surgical clip placement across the neck a difficult task. However, despite the higher chances of morbidity, microsurgery is an effective treatment modality due to lower recurrence rates...

The increasing number of incidental intracranial aneurysms creates a dilemma of which aneurysms to treat and which to observe. Clinical scoring systems consider risk factors for aneurysm rupture however objective parameters for assessment of aneurysms stability are needed. We retrospectively analysed contrast enhancing behaviour of un-ruptured aneurysms in the black blood magnetic resonance imaging (MRI) in N=71 patients with 90 aneurysms and assessed correlation between aneurysm wall contrast enhancement (AWCE) and aneurysm anatomy and clinical scoring systems...
