Ruptured intracranial aneurysm usually manifests as subarachnoid hemorrhage (SAH) or SAH with hematoma. Aneurysms that only present with intracerebral hemorrhage or intraventricular hemorrhage are mostly confined to the distal artery. It is very rare that ruptured middle cerebral artery bifurcation aneurysms manifest signs of caudate head hemorrhage extending into the cerebral ventricle. One su...

We report on a large fusiform aneurysm in a 20-year-old male with a history of cerebral palsy. Aneurysm location relative to four anatomical posterior cerebral artery segments dictates which approach should be used for treatment: pterional transsylvian, subtemporal, or parietooccipital interhemispheric transtentorial approach. A right temporal craniotomy via a subtemporal approach was performed...

BACKGROUND AND PURPOSE The rupture of a cerebral aneurysm is a major cause of subarachnoid hemorrhage, but the mechanism of its development remains unclear. Inducible nitric oxide synthase (iNOS) is expressed in human and rat cerebral aneurysms, and aminoguanidine, a relatively selective inhibitor of iNOS, can decrease the number of the aneurysms in rats. In this study we applied our new mouse ...

Purpose: This study was designed to quantify and characterize the variations of hemodynamic parameters for those large cerebral aneurysms with outflow vessel in the plane of main vortex. Materials and Methods: A total of 19 consecutive patients with large cerebral aneurysms were constructed with the data of digital subtraction angiography. Those large cerebral aneurysms with outflow vessel in t...

Complete spontaneous thrombosis followed by recanalization of non-giant aneurysms is a rare event that can be discovered incidentally on advanced neural images. In this case report, the authors described a woman who presented with subarachnoid hemorrhage (SAH) and left posterior cerebral artery (PCA) territory ischemic stroke. Cerebral angiography revealed a left PCA aneurysm at the P1-P2 junct...

This report presents 8 cases of internal carotid artery aneurysms, 1 case of a middle cerebral artery aneurysm, and 2 cases of anterior cerebral artery aneurysms, together with a discussion of the treatment of aneurysms in anterior circulation. All cases showed subarachnoid hemorrhage. Two of the 8 internal carotid artery aneurysms were trapped with a low-flow bypass; however, both patients die...

We report what may be the first case of lipoma of the corpus callosum associated with a distal anterior cerebral artery saccular aneurysm. The pathogenetic correlation between the callosal lipoma and the distal anterior cerebral artery saccular aneurysm is discussed.

The objective of this review is to review the anaesthetic implications of vasoactive compounds particularly with regard to the cerebral circulation and their clinical importance for the practicing anaesthetist. Material was selected on the basis of validity and application to clinical practice and animal studies were selected only if human studies were lacking. Hypotensive drugs have been used ...

Introduction: Intracranial aneurysms consist in abnormal dilatation of the cerebral arteries, most frequently asymptomatic, with symptoms appearing case aneurysm rupture. From an imaging point view, a cranial CT scan shows subarachnoid haemorrhage caused by rupture and “gold standard” for diagnosis is angiography.
 Case presentation: A 49 years-old female, Ukrainian refugee, presented uniq...
