Fusiform aneurysms of cerebral arteries are less prevalent than saccular aneurysms and are rarely associated with subarachnoid hemorrhage (SAH). In this article, we report SAH due to a rare case of bilateral fusiform aneurysm of the supraclinoid segment of the internal carotid arteries (ICAs) (C4 segment of the ICA).

PURPOSE: To evaluate the relationship between anterior cerebral artery (ACA) velocities (and ancillary parameters) and ACA infarction following aneurysmal subarachnoid hemorrhage (aSAH), and to examine the factors that influence velocities. METHODS: Retrospective investigation of 500 consecutive aSAH patients. ACA mean velocities (Vm) were evaluated by daily transcranial ultrasound during the early (days 1-4) and late (days 5-20) periods posthemorrhage. Presence and timing of acute ACA infarctions were identified by serial retrospective review of cerebral computerized tomography (CT) scans...

<i>Multiple fusiform aneurysms occurring in a single patient are very uncommon. Fusiform aneurysms affecting the anterior circulation are extremely rare and reported cases involve the middle cerebral artery and internal carotid artery. We report here a case of a 55-year-old African American male who had a history of multiple strokes and who was found unresponsive prior to his latest hospital admission. Neuroimaging was remarkable for multiple fusiform aneurysms involving segments of the anterior, middle and posterior cerebral arteries as well as subarachnoid and intraparenchymal hemorrhage...

BACKGROUND: Delayed cerebral ischemia (DCI) is a cause of poor outcome after aneurysmal subarachnoid hemorrhage. Risk scales to predict DCI have scarcely been evaluated for predictive accuracy. Accounting for volume of intraventricular hemorrhage (IVH) in the modified Fischer scale (mFS) may improve its predictive accuracy. OBJECTIVE: To compare the modified Graeb score (mGS) to the mFS for risk prediction of DCI, and to investigate whether incorporating an mGS cut-point into the mFS could improve predictive accuracy...

Pretruncal (perimesencephalic) non-aneurysmal subarachnoid hemorrhage (PNSAH) is uniformly associated with an excellent outcome. Although cerebral vasospasm remains a common complication of SAH and constitutes an important predictor of outcome, in the setting of PNSAH, it is extremely rare. Preturnal non-aneurysmal subarac refers to a subset of SAH patients with a characteristic pattern of localized blood on CT of the head, normal cerebral angiography, and benign course when compared to the aneurysmal SAH population...

We report a case of giant aneurysm causing subarachnoid hemorrhage in a pregnant female. A 25-year-old female presented with sudden onset of severe headache and vomiting with altered sensorium and right hemiplegia. On investigation, she had a giant supraclinoid segment internal carotid artery (ICA) aneurysm. She was planned for digital substraction angiography, but during the procedure she deteriorated neurologically and went into spontaneous labor. The baby was a male child with weight of 1.1 kg. She was taken up for surgery and aneurysm was clipped...

We report a case of dissecting aneurysm of the right posterior cerebral artery presenting with sudden onset headache and altered behavior during labor. A 26-year-old P1001 with uncomplicated antenatal period, except history of headache off and on since 32 weeks of pregnancy, developed sudden onset headache and altered behavior during 3(rd) stage of labor. She had vaginal delivery and a live born male baby was delivered with good Apgar score. The CT was suggestive of subarachnoid hemorrhage and DSA was suggestive of dissecting aneurysm of the right P2 segment with hypoplasia of right P1 segment and A1 segment of posterior and anterior cerebral artery, respectively...

Ophthalmic artery aneurysms account for 5% of all cerebral aneurysms and are an important cause of morbidity and mortality related to subarachnoid hemorrhage. The diagnosis is often made only when the aneurysm is large enough to become symptomatic. They remain technically challenging for both neurosurgeon and interventional radiologist. We present the case of a 62-year-old woman admitted for transient loss of consciousness, followed by generalized tonic-clonic seizures. Computed tomography (CT) showed a subarachnoid hemorrhage (SAH), clinically graded as Hunt and Hess III...

BACKGROUND: Aneurysm rebleeding following presentation with aneurysmal subarachnoid hemorrhage (aSAH) is associated with high mortality and poor functional outcome. While a substantial genetic contribution to aneurysm formation and rupture is known, the genetic influence on the risk of rebleeding is poorly understood. OBJECTIVE: To evaluate the role of common endothelin polymorphisms in aneurysm rebleeding. PATIENTS AND METHODS: Blood sample from all patients enrolled in the CARAS (Cerebral Aneurysm Renin Angiotensin System) study were used for genetic evaluation...

BACKGROUND AND PURPOSE: Intracranial aneurysm (IA), common in general public, causes lethal subarachnoid hemorrhage on rupture. Prevention of rupture of IA is therefore socially important. However, there is currently no medical treatment. Recent studies suggest that IA is a disease of chronic inflammation in the arterial wall caused by endothelial dysfunction and infiltrated macrophages. Sphingosine-1-phosphate receptor type 1 (S1P1 ) is present on the endothelium and promotes its barrier function...

OBJECTIVE Subarachnoid hemorrhage (SAH) is treated with either surgical clipping or endovascular coiling, though the latter is the preferred treatment method given its more favorable functional outcomes. However, neuropsychological functioning after treatment is rarely taken into account. In this meta-analysis, the authors synthesized relevant data from the literature and compared neuropsychological functioning in patients after coiling and clipping of SAH. They hypothesized that the coiled patients would outperform the clipped patients; that group differences would be greater with higher posterior circulation rupture rates, in older patients, and in more recent publications; that group differences would be smaller with greater rates of middle cerebral artery (MCA) rupture; and that anterior communicating artery (ACoA) rupture rates would not influence effect sizes...
