Atherosclerotic intracranial arterial（ICA） stenosis and intracranial aneurysms are the common causes of ischemic stroke and hemorrhagic stroke, respectively. Investigators aimed to ass...
Intracranial aneurysms are common in the general population. The overall prevalence of unruptured intracranial aneurysms (UIAs) is estimated of 2.3-3.2% in the population without specific ...
A prospective, multicenter, observational assessment of the safety and effectiveness of the LVIS® device in the treatment of wide necked intracranial aneurysms.
This is a prospective, multicenter, observational study, aiming at comparing the Safety and effectiveness among the different surgical treatment of unruptured intracranial aneurysms in Chi...
Flow disruption is a new endovascular approach for treatment of both ruptured and unruptured intracranial aneurysms, which involves placement of an endosaccular device (WEB) which modifies...
There is a controversy concerning the risk of rupture of small intracranial aneurysms. We sought to determine the size and morphological features of ruptured intracranial aneurysms.
Only a minority of intracranial aneurysms rupture to cause subarachnoid hemorrhage.
There are conflicting data between natural history studies suggesting a very low risk of rupture for small, unruptured intracranial aneurysms and retrospective studies that have identified a much high...
Aneurysms in various arterial beds have common risk- and genetic factors. Data on the correlation of extracranial carotid artery aneurysms (ECAA) with aneurysms in other vascular territories are lacki...
Inflammation as a significant influence factor plays an important role in the formation and rupture of intracranial aneurysms. However, based on plenty of related studies, it is believed that the hepa...
Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)
A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.
Aneurysm of the MICROVASCULATURE. Charcot–Bouchard aneurysms are aneurysms of the brain vasculature which is a common cause of CEREBRAL HEMORRHAGE. Retinal microaneurysm is an early diagnostic sign of DIABETIC RETINOPATHY.
A well-circumscribed mass composed of tuberculous granulation tissue that may occur in the cerebral hemispheres, cerebellum, brain stem, or perimeningeal spaces. Multiple lesions are quite common. Management of intracranial manifestations vary with lesion site. Intracranial tuberculomas may be associated with SEIZURES, focal neurologic deficits, and INTRACRANIAL HYPERTENSION. Spinal cord tuberculomas may be associated with localized or radicular pain, weakness, sensory loss, and incontinence. Tuberculomas may arise as OPPORTUNISTIC INFECTIONS, but also occur in immunocompetent individuals.
Embolism or thrombosis involving blood vessels which supply intracranial structures. Emboli may originate from extracranial or intracranial sources. Thrombosis may occur in arterial or venous structures.
