BACKGROUND Subarachnoid hemorrhage (SAH) due to intracranial aneurysm rupture is a major neurosurgical emergency associated with significant morbidity and mortality. Rapid aneurysm growth is associated with rupture. Systemic lupus erythematosus (SLE) is a multi-system autoimmune disorder whose complications can include cerebral vasculitis and vasculopathy. Intracranial aneurysms are not known t...

BACKGROUND AND PURPOSE The purpose of this study was to establish whether individuals with a family history of >/=2 first-degree relatives with intracranial aneurysm should be offered screening for aneurysm. METHODS We derived 3 theoretical models and calculated the outcomes of screening with magnetic resonance angiography (MRA) followed by digital subtraction angiography (DSA) if MRA was pos...

The co-occurrence of a brain arteriovenous malformation, Moyamoya Disease, and intracranial aneurysm is exceedingly rare. We report the third case this disease constellation, first where arises from collateral vessel. review relevant literature discuss proposed pathophysiological mechanisms clinical implications.

BACKGROUND AND PURPOSE Knowledge about risk factors contributes to understanding the pathophysiological mechanisms that cause intracranial aneurysm rupture and helps to develop possible treatment strategies. We aimed to study lifestyle and personal characteristics as risk factors for the rupture of intracranial aneurysms. METHODS We performed a case-control study with 250 patients with an ane...

BACKGROUND AND PURPOSE Understanding risk factors for intracranial aneurysm growth is important for patient management. We performed a meta-analysis examining risk factors for intracranial aneurysm growth in longitudinal studies and examined the association between aneurysm growth and rupture. MATERIALS AND METHODS We searched the literature for longitudinal studies of patients with unrupture...

This case report presents a fully thrombosed large aneurysm of middle cerebral artery mimicking an intra-axial brain tumor in a 54-year-old male patient. A small mass like lesion was found incidentally in right frontal area. Brain magnetic resonance image showed dark signal intensity on T2-weighted images and peripheral high signal intensity on T1-weighted images with peripheral rim enhancement...

Image-based computational fluid dynamics holds a prominent position in the evaluation of intracranial aneurysms, especially as a promising tool to stratify rupture risk. Current computational fluid dynamics findings correlating both high and low wall shear stress with intracranial aneurysm growth and rupture puzzle researchers and clinicians alike. These conflicting findings may stem from incon...

The intracranial stent functions primarily to prevent protrusion of coils into the parent vessel during the embolization of wide-necked cerebral aneurysms and might also reduce aneurysm recanalization rate. In spite of these advantages, little is known about the long-term interaction of the stent with the parent vessel wall. We present a rare case of severe in-stent stenosis occurring as a dela...

conclusion results reinforced the pivotal role of vascular geometry, with respect to hemodynamics, together with the importance of performing patient-specific cfd analyses, through which the effect of different blood flow conditions on the aneurysm hemodynamics could be evaluated. objectives this study aimed to investigate the effects of variations in heart rate and internal carotid artery (ica...

The authors present an extremely rare case of a 48-year-old female who developed repeated perianeurysmal edema at 2, 9, and 16 weeks after endovascular coil embolization for the ruptured intracranial aneurysm. Interestingly, the mechanism for this edema could be different at each time point in this case; acute thrombosis formation, chemical inflammation, and aneurysm recanalization. We have to ...
