Successful Treatment of Growing Basilar Artery Dissecting Aneurysm by Pipeline Flow Diversion Embolization Device
We describe a case of successful management of a growing basilar artery dissecting aneurysm by the Pipeline flow diversion embolization device (PED). A 48-year-old woman presented with severe headache, neck pain, and altered consciousness. Computed tomography showed subarachnoid hemorrhage located in basal cisterns, with a pontine infarct shown on magnetic resonance imaging. Digital subtraction angiography showed dissecting aneurysm of the trunk of the basilar artery, with growth over time on repeated imaging. Repeated imaging demonstrated growth in size of the aneurysm. The aneurysm was treated with PED with complete obl...

Fusiform Dilatation of the Outer Contour of a Dissected Anterior Cerebral Artery Revealed by Magnetic Resonance Cisternography in a Patient with Simultaneous Cerebral Infarction and Subarachnoid Hemorrhage
A 46-year-old man presented with right hemiparesis. Cranial magnetic resonance (MR) imaging revealed both an acute cerebral infarction in the territory of the left anterior cerebral artery (ACA) and a thin subarachnoid hemorrhage in the left superior frontal sulcus. MR angiography revealed stenosis at the A2 segment of the left ACA. MR cisternography was, therefore, performed on day 12 after admission using sagittal, 3-dimensional, heavily T2-weighted images. Fusiform dilatation of the outer contour was confirmed by MR cisternography at the region of narrowing identified by MR angiography. This case indicates that the comb...

Impact of Aneurysm Location on Cardiopulmonary Dysfunction after Subarachnoid Hemorrhage
Conclusions: Aneurysm location affects cardiac output, vascular resistance, and pulmonary edema in biphasic fashion. Patient age and location of aneurysm in the ACA may be risk factors for cardiac failure after SAH.

Hydroperoxide in Internal Jugular Venous Blood Reflects Occurrence of Subarachnoid Hemorrhage-Induced Delayed Cerebral Vasospasm
Background: To investigate the association between subarachnoid hemorrhage-induced delayed cerebral vasospasm (DCVS) and oxidative stress, an oxidation product, hydroperoxide, was measured in 3 specimens: peripheral arterial blood, cerebrospinal fluid (CSF), and internal jugular venous blood (IJVB).Methods: Hydroperoxide was measured using the diacron reactive oxygen metabolites (d-ROMs) test. The hydroperoxide levels were evaluated based on the rate of change in the d-ROMs test value on day 6 relative with that on day 3 (d-ROMs change rate).Results: The subjects were 20 patients. The d-ROMs change rate in IJVB was signifi...

Intracranial Vascular Calcification is Protective from Vasospasm after Aneurysmal Subarachnoid Hemorrhage
The objective of this study was to assess the association between intracranial calcification, a marker for atherosclerosis, and vasospasm. Charts and nonenhanced computed tomography scans of patients with subarachnoid hemorrhage were retrospectively reviewed. Transcranial Doppler studies were used to categorize vasospasm using mean flow velocity: mild vasospasm 120-199 cm/second and severe ≥200 cm/second.

Cervical Spinal Epidural Arteriovenous Fistula with Coexisting Spinal Anterior Spinal Artery Aneurysm Presenting as Subarachnoid Hemorrhage—Case Report
Hemorrhagic presentation of spinal epidural arteriovenous fistulas (AVFs) is rare in patients with cervical spinal vascular lesions. The present report describes a patient with cervical spine epidural AVFs associated with anterior spinal artery aneurysm at the same vertebral level presenting with subarachnoid hemorrhage. A 54-year-old man presented with sudden onset of headache. Computed tomography of the head showed subarachnoid hemorrhage. Diagnostic angiography revealed an epidural AVF located at the C1-2 level that was fed mainly by the dorsal somatic branches of the segmental arteries from the radicular artery and anterior spinal artery.

Subarachnoid Extension of Hemorrhage is Associated with Early Seizures in Primary Intracerebral Hemorrhage
The objective of this study is to evaluate whether subarachnoid hemorrhage extension (SAHE) is associated with early seizures in patients with primary ICH.

Transfer Time to a High-Volume Center for Patients with Subarachnoid Hemorrhage Does not Affect Outcomes
The objective of our study was to examine patients with aneurysmal subarachnoid hemorrhage transferred and directly admitted to our institution in order to determine how transfer time affects outcomes.

Diffuse Patterns of Nonaneurysmal Subarachnoid Hemorrhage Originating from the Basal Cisterns Have Predictable Vasospasm Rates Similar to Aneurysmal Subarachnoid Hemorrhage
Nonaneurysmal subarachnoid hemorrhage (SAH) has been historically associated with a benign clinical course. However, recent studies have suggested that nonaneurysmal SAH can present with different hemorrhage patterns that may be associated with differential rates of morbidity. Herein, we analyze a retrospective consecutive cohort of patients with nonaneurysmal SAH to determine outcomes. We also seek to evaluate a validated radiographic grading scale to determine its utility in predicting vasospasm in the setting of different hemorrhage patterns.

Ruptured Cerebral Microaneurysm Diagnosed by 3-Dimensional Fast Spin-Echo T1 Imaging with Variable Flip Angles
Cerebral microaneurysms, which are 2 mm or small in size, are a rare cause of subarachnoid hemorrhage (SAH). The authors present 2 cases with ruptured microaneurysms, in which 3-dimensional (3D) fast spin-echo T1 imaging with variable flip angles (CUBE T1) using gadolinium-diethylenetriaminepentaacetic acid (Gd) enhancement was useful in diagnosing the microaneurysms as the source of bleeding. Case 1 was a 61-year-old woman who had an SAH localized to the left Sylvian fissure. A small bulge (1.4 mm) at the bifurcation of left middle cerebral artery (MCA), which was detected by 3D angiography, was well enhanced by CUBE T1...

Dissecting Aneurysm of Anterior Inferior Cerebellar Artery Initially Presenting with Nonhemorrhagic Symptom
We report a patient with a probable dissecting aneurysm of the anterior inferior cerebellar artery (AICA) initially presenting with a nonhemorrhagic symptom, which resulted in subarachnoid hemorrhage. A 61-year-old woman suddenly experienced nausea. Computed tomography (CT) on admission showed a high-density mass with a double lumen in the right cerebellopontine angle without subarachnoid hemorrhage. Five days after the onset, she suddenly lost consciousness. CT demonstrated subarachnoid hemorrhage.

Cerebral Blood Flow after Acute Bypass with Parent Artery Trapping in Patients with Ruptured Supraclinoid Internal Carotid Artery Aneurysms
Bypass with parent artery trapping is an alternative treatment method for ruptured internal carotid artery (ICA) aneurysms when clipping or coiling is contraindicated. However, the efficacy and safety of this strategy during the acute stage of subarachnoid hemorrhage (SAH) is undetermined.
