Persistent Local Vasogenic Edema with Dynamic Change in the Regional Cerebral Blood Flow after STA-MCA Bypass for Adult Moyamoya Disease
We report an adult moyamoya disease (MMD) patient who developed persistent local vasogenic edema with dynamic change in the regional cerebral blood flow after left superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis. A 49-year-old woman with ischemic-onset MMD underwent left STA-MCA anastomosis. Magnetic resonance (MR) imaging of fluid-attenuated inversion recovery 1 day after surgery revealed an asymptomatic local high-signal-intensity lesion at the site of anastomosis, and MR angiography demonstrated apparently patent STA-MCA bypass.

Association between Enlarged Perivascular Spaces and Internal Carotid Artery Stenosis: A Study in Patients Diagnosed by Digital Subtraction Angiography
Objective: An enlarged perivascular space (EPVS) is an imaging marker of cerebral small vessel disease, and its relationship with large artery disease is elusive. We investigated the EPVS in patients with internal carotid artery stenosis (ICAS) with the use of digital subtraction angiography (DSA) and tested the relationship between the degree of EPVS and the degree of ICAS; as well as the relationship between the degree of EPVS and white matter hyperintensity (WMH). Method: A total of 202 patients with or without ICAS diagnosed by DSA were enrolled.

Carotid Revascularization and Its Effect on Cognitive Function: A Prospective Nonrandomized Multicenter Clinical Study
Background: There is conflicting data on the effect of carotid revascularization on cognitive function. Objective: To examine cerebral blood flow and cognitive function after carotid revascularization. Methods: Patients with unilateral, asymptomatic hemodynamically significant carotid artery stenosis (80% by computed tomography angiography or magnetic resonance angiography) were eligible. Cerebral blood flow was measured preoperatively and 1 month postoperatively using quantitative phase contrast magnetic resonance angiography.

Procedural Complications and Factors Influencing Immediate Angiographic Results after Endovascular Treatment of Small ( < 5 mm) Ruptured Intracranial Aneurysms
With advances in neurointerventional device technology and increased experience with aneurysm embolization, endovascular treatment (EVT) has become a widely accepted modality to treat intracranial aneurysms (IAs) [1]. During EVT of IAs, aneurysms are packed as densely as possible, which makes it exceedingly difficult to implant coils while ensuring safety and complete occlusion [2,3]. However, there appears to be a paradoxical challenge for small ruptured aneurysms (SRAs,

Carotid Calcium Volume and Stenosis after Stent Implantation
Internal carotid artery (ICA) stenosis could be treated with stent placement. It was hypothesized that calcium amount could be predictive of vessel stenosis after stent placement. We utilised computed tomography (CT) angiography to quantify volume of calcium material in bulbar ICA.

Detection of impaired cerebrovascular reactivity in patients with chronic cerebral ischemia using whole-brain 7T MRA
We examined whether whole-brain magnetic resonance angiography (MRA) at 7T could non-invasively detect impaired CVR in patients with chronic cerebral ischemia by demonstrating the leptomeningeal collaterals (LMCs).

Arterial transit artifacts observed by arterial spin labeling in Moyamoya disease
Moyamoya disease is a progressive cerebral vascular disease of unknown etiology. It is characterized by stenosis or occlusion around the terminal portion of the internal carotid arteries, with abnormal collateral networks called Moyamoya vessels.1,2 Digital subtraction angiography (DSA) is still the gold standard for assessing the collateral circulation of Moyamoya disease, although recent advancements in magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) has enabled a high diagnostic accuracy.

Flow evaluation of STA –MCA bypass using quantitative ultrasonography: An alternative to standard angiography for follow up of bypass graft
To date, digital subtraction angiography (DSA) has been considered as the gold imaging modality for assessing graft patency after extracranial –intracranial bypass. The utility of a noninvasive and quantitative method of assessing graft flow postoperatively was evaluated by using quantitative ultrasonography.

Giant Cerebellar Cavernomas in Pediatric Patients: Systematic Review with Illustrative Case
Giant cavernomas (GCMs) are angiographically occult vascular malformations of the central nervous system measuring at least 4 cm in diameter. These are rare lesions, especially in the cerebellum. As such, the clinical and radiologic features, surgical management, and outcomes of treatment for this condition are unknown.

Relative Alpha Variability Changes Precede Alpha-Delta Ratio Changes in Cerebral Ischemia
We present a case of aneurysmal subarachnoid hemorrhage complicated by vasospasm as detected by the cerebral angiogram. The patient was being monitored on electroencephalogram. It showed early signs of cerebral ischemia represented by decline in the Alpha-Delta-Ratio (ADR) and the Relative-Alpha-Variability (RAV). Surprisingly, the RAV changes preceded the ADR changes. This is a significant finding that can also apply to early reocclusion or reperfusion injuries after mechanical thrombectomy.

Subarachnoid Hemorrhage Caused by Ruptured Aneurysm of the Artery of Adamkiewicz: a Case Report
A 66-year-old man presented with a 6-day history of progressive posterior cervical pain that included lower back pain and fever. Neurological examinations revealed neck stiffness. Computed tomography demonstrated convexity subarachnoid hemorrhage. A spinal T2-weighted image revealed a hypointense signal lesion with contrast enhancement of the intradural extramedullary space at Th12 –L1. Digital subtraction angiography showed a fusiform aneurysm with a 10 mm diameter in the artery of Adamkiewicz. We diagnosed the patient's condition as a ruptured aneurysm of the artery of Adamkiewicz.

Fatal Brain Injury Following Carbon Dioxide Angiography
Carbon dioxide (CO2) as a contrast agent has been in use as early as the 1920s for visualization of retroperitoneal structures. Digital subtraction angiography (DSA) using CO2 as a contrast agent for vascular imaging was developed in the 1980s. Currently, CO2 angiography is an alternative agent in patients with chronic kidney disease (CKD) and those who are at risk of developing contrast-induced nephropathy. However, CO2 causes neurotoxicity if the gas inadvertently enters the cerebrovascular circulation leading to fatal brain injury.

Attempt to delineate occluded arteries with initial plain computed tomography in acute cerebral arterial occlusion
Several randomized controlled trials have investigated the effects of endovascular thrombectomy using stent retrievers for acute cerebral arterial occlusion.1 –4 Endovascular thrombectomies have generally proceeded without anatomical information regarding the affected intracranial arteries, and this could cause complications such as vessel perforation.5–7 Several recent studies have visualized occluded arteries using various imaging modalities, includ ing three-dimensional computed tomography (CT) angiography,8 magnetic resonance imaging (MRI),9,10 and cone-beam CT.
