BACKGROUND: Unruptured intracranial aneurysms (IAs) are typically asymptomatic and undetected except for incidental discovery on imaging. Blood-based diagnostic biomarkers could lead to improvements in IA management. This exploratory study examined circulating neutrophils to determine whether they carry RNA expression signatures of IAs. METHODS: Blood samples were collected from patients receiving cerebral angiography. Eleven samples were collected from patients with IAs and 11 from patients without IAs as controls...

Endovascular treatment and prognosis of intracranial aneurysms are based on size and volume, which demand more accurate neuroimaging techniques. Aneurysm volume calculation is important to choose endovascular treatment modalities and packing density calculation. Of all these methods, it remains unknown which one is the most accurate to calculate aneurysm volume. The objective of this study is to compare the accuracy of three angiography-based versus three tomographic-based methods which calculate aneurysm volume...

INTRODUCTION: Abnormalities in Matrix Metalloproteinase (MMP) genes, which are important in extracellular matrix (ECM) maintenance and therefore arterial wall integrity are a plausible underlying mechanism of intracranial aneurysm (IA) formation, growth and subsequent rupture. We investigated whether the rs243865 C > T SNP (single nucleotide polymorphism) within the MMP-2 gene (which influences gene transcription) is associated with IA compared to matched controls. MATERIALS AND METHODS: We conducted a case-control genetic association study, adjusted for known IA risk factors (smoking and hypertension), in a UK Caucasian population of 1409 patients with intracranial aneurysms (IA), and 1290 matched controls, to determine the association of the rs243865 C > T functional MMP-2 gene SNP with IA (overall, and classified as ruptured and unruptured)...

OBJECTIVE Long-term follow-up results of the treatment of unruptured intracranial aneurysms (UIAs) by means of coil embolization remain unclear. The aim of this study was to analyze the frequency of rupture, retreatment, stroke, and death in patients with coiled UIAs who were followed for up to 20 years at multiple stroke centers. METHODS The authors retrospectively analyzed data from cases in which patients underwent coil embolization between 1995 and 2004 at 4 stroke centers. In collecting the late (≥ 1 year) follow-up data, postal questionnaires were used to assess whether patients had experienced rupture or retreatment of a coiled aneurysm or any stroke or had died...

Traumatic pseudoaneurysms of the middle meningeal artery (MMA) represent less than 1% of all intracranial aneurysms, and occur mostly in association with temporal bone fractures following head trauma. Given the unknown natural history, it is unclear whether they should be treated. We present two cases of MMA pseudoaneurysms discovered during trauma workups. The first patient is a 44-year-old male with severe traumatic brain injury (TBI) following a motor vehicle accident. The patient was found to have two right-sided middle meningeal artery pseudoaneurysms that were treated successfully with Onyx® (Medtronic, Minneapolis, MN) embolization...

OBJECTIVE: The transciliary keyhole approach has been actively employed for unruptured intracranial aneurysms in many institutions, although applying this technique to ruptured aneurysms remains controversial. We investigated the risk factors related to poor surgical outcomes in ruptured aneurysm and attempted to clarify the differences between conventional craniotomy and keyhole surgery. METHODS: A total of 188 patients who underwent keyhole surgery due to ruptured anterior circulation aneurysms were enrolled at a single institution...

PURPOSE: Coiling associated with placement of a self-expandable intracranial stent has improved the treatment of intracranial wide-necked aneurysms. Little is known, however, about the durability of this treatment. The purpose of this report is to present our experience with the LEO stent and to evaluate the complications, effectiveness, and long-term results of this technique. METHODS: We analyzed the records of 155 intracranial unruptured aneurysms that were treated by stent-assisted coiling with a LEO stent between 2008 and 2012...

A 71-year-old woman presented with a sudden onset of headache and vomiting. Computed tomography(CT)showed diffuse subarachnoid hemorrhage(SAH)that was more severe on the right side. Three-dimensional CT angiography and right carotid angiography(CAG)demonstrated 2-mm microaneurysms at the middle cerebral artery(MCA)bifurcation and anterior communicating artery, with slight narrowing and dilatation of the M2 inferior trunk. Each microaneurysm was smooth, making it difficult to identify the bleeding source. Thus, surgery was postponed at the acute stage, and further investigation was planned...

Spontaneous regression of an unruptured aneurysm is very rare. We present a case of a 64-year-old woman with an unruptured cerebral aneurysm in which spontaneous regression occurred after contralateral clipping. High-resolution magnetic resonance imaging showed that the aneurysm had decreased in size and there was no evidence of thrombus. Level of Evidence Case, Level IV.

BACKGROUND: Anterior cerebral artery aneurysms (ACAs) are characterized by higher rupture rate and small size at rupture. It was revealed that the aneurysm-to-vessel size ratio, and not the absolute size, might predict the risk of rupture in small unruptured intracranial aneurysms.The present study aimed to investigate the relationship between a size ratio and outcome in patients with unruptured non-dissecting ACA aneurysms (UNDAs). METHODS: Consecutive 187 patients with 12 A1 (6...

Background Treatment of true ophthalmic artery (OA) or anterior choroidal artery (AChA) aneurysms with preservation of the parent vessel may be challenging. Flow diverters have limitations when dealing with branch vessels arising from the aneurysm sac. Visual loss or AChA territory infarcts have been reported both for surgical and endovascular treatment. Methods We evaluated the safety and efficacy of an open-cell design, laser-cut, self-expanding Nitinol stent, and use of cone-beam computed tomography (CBCT) for stent-assisted coil embolization...

Despite major developments in treating intracranial aneurysms by endovascular coil embolization, complete occlusion of the entire aneurysmal neck remains a problem. We present a novel endovascular strategy for middle- and large sized aneurysms called the "hemispheric divided coiling technique" and compare the short-term follow-up results of this technique with those of conventional coil embolization. Ten patients (mean age, 69.7 ± 9.7 years) with middle- or large-sized ruptured or unruptured intracranial aneurysms (mean maximum aneurysmal diameter, 12...
