BACKGROUND Mycotic aneurysm is a rare potentially life-threatening complication of infective endocarditis (IE). Little data is available on the management and outcomes of ruptured mycotic aneurysms with large intracerebral hematoma. Few cases have been described on the management of mycotic aneurysm in the presence of life-threatening hematoma and mass effect. CASE DESCRIPTION We are presenti...

Subarachnoid hemorrhage (SAH) is a potentially lethal disease with high morbidity and mortality. The goal of endovascular intracranial aneurysm treatment of intracranial aneurysms is the prevention of rebleeding after primary SAH, the prevention of SAH in unruptured aneurysms or the alleviation of other symptoms attributable to the aneurysm. Securing ruptured aneurysms improves outcome after SA...

The equipment and techniques associated with magnetic resonance imaging (MRI) have rapidly evolved. The development of 3.0 Tesla MRI has enabled high-resolution imaging of the intracranial vessel wall. High-resolution MRI (HRMRI) can yield excellent visualization of both the arterial wall and lumen, thus facilitating the detection of the primary and secondary features of intracranial arterial d...

ABSTRACTOBJECTIVETo review the current knowledge of screening and treatment of asymptomatic unruptured intracranial aneurysms (AUIAs) using a case-based approach.SOURCES OF INFORMATIONPubMed was searched from January 1995 to January 2008 using the phrase unruptured intracranial aneurysm. Scientific statements of the Stroke Council of the American Heart Association pertaining to intracranial ane...

Cerebral hernia induced by intracranial haematoma in patients with poor-grade ruptured intracranial aneurysm is a severe disease, which is associated with high mortality rates. This study aims to discuss the treatment principle of cerebral hernia caused by intracranial haematoma due to ruptured intracranial aneurysms-without preoperative angiography. 17 patients of cerebral hernia induced by an...

BACKGROUND AND PURPOSE This study was undertaken to assess the utility of contrast-enhanced MR angiography at 6 months after endovascular treatment of intracranial aneurysms with Guglielmi detachable coils. METHODS Contrast-enhanced MR angiography was performed in 47 patients at 6 and 12 months after endovascular treatment of intracranial aneurysms (48 aneurysms). Digital subtraction angiogra...

A 38-year-old woman had complex, congenital heart anomalies, including double-outlet right ventricle with mitral atresia, severe left ventricle hypoplasia, atrial septal defect, and severe pulmonary stenosis, for which she had not received appropriate treatment. She presented to our institution with an intense sudden-onset headache that had initiated while sleeping. Brain computed tomography in...

BACKGROUND AND PURPOSE Management strategies for unruptured intracranial aneurysms (UIAs) are controversial. This study aimed to identify surrogate parameters that highly predict the rupture risk of small (<5 mm) UIAs. METHODS Radiological data were collected from 854 patients with aneurysmal subarachnoid hemorrhages who were enrolled in the Sapporo SAH Study. They had a total of 854 ruptured...

BACKGROUND AND PURPOSE There is a controversy about the time span over which cerebral aneurysms develop. In particular, it is unknown whether collagen in ruptured aneurysms undergoes more rapid turnover than in unruptured aneurysms.(14)C birth dating of collagen could be used to address this question. METHODS Aneurysmal domes from patients undergoing surgical treatment for ruptured or unruptu...

Intracranial aneurysms are uncommon in children. Rupture of giant intracranial aneurysms is extremely uncommon in infants even in autopsy studies. In this report, we present an unusual case of ruptured giant middle cerebral artery aneurysm in an 11-month-old female infant who presented acutely with unresponsiveness and seizures. The aneurysm was clipped during an urgent craniotomy for evacuatio...
