Arterial spin labeling (ASL) is a magnetic resonance (MR) imaging technique used to assess cerebral blood flow noninvasively by magnetically labeling inflowing blood. In this article, the main labeling techniques, notably pulsed and pseudocontinuous ASL, as well as emerging clinical applications will be reviewed. In dementia, the pattern of hypoperfusion on ASL images closely matches the established patterns of hypometabolism on fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) images due to the close coupling of perfusion and metabolism in the brain...

Neurovascular emergencies, consisting of acute ischemic stroke, non-traumatic aneurysmal subarachnoid hemorrhage, arteriovenous malformation, dural arteriovenous fistula, and carotid- cavernous fistula, can have an acute presentation to the emergency department. Radiologists should have an understanding of these processes and their imaging findings in order to provide a prompt and accurate diagnosis. Neurointerventional radiology plays a critical role in providing additional diagnostic information and potentially curative treatment...

Spinal dural arterio-venous fistula (SDAVF) is a common type of spinal vascular malformation. Surgical obliteration of the fistula can cure SDAVF anatomically, but the functional outcome is unsatisfactory.The aim of the study was to evaluate the effect of hyperbaric oxygen therapy (HBOT) on the functional recovery of postoperative SDAVF patients.This prospective cohort study included postoperative SDAVF patients. Patients were divided into control and HBOT groups. Patients in control group received conventional treatment, whereas those in the HBOT group received conventional treatment plus HBOT (2...

Intracranial arteriovenous shunts (ICAVSs) in young children are characterized with frequent high flow fistulas. In association of high flow fistulas and physiological condition of the developing brain and heart, each disease tends to present at a certain age with unique symptoms. Vein of Galen aneurysmal malformation (VGAM) and dural sinus malformation (DSM) with arteriovenous (AV) shunts tend to present in neonate with high output cardiac failure. In infancy, VGAM, pial AVF and infantile dural AVF tend to present with hydrodynamic disorder such as macrocephaly, ventriculomegaly, prominent facial veins, and developmental delay...

This is a case report of de novo development of two cerebral cavernous malformations adjacent to existing developmental venous anomalies. The development of cavernomas was noted over a follow-up period of 10 years. These developments happened during the course of staged endovascular management of a complex dural arterio-venous fistula along the right sphenoid wing. The patient presented with a proptosis secondary to lympho-haemangiomatous lesion of the fronto-orbital region and a high-flow right sphenoid wing dural arterio-venous fistula...

BACKGROUND: Isolated distal vaginal agenesis is a rare anomaly and mostly becomes symptomatic after menarche. We describe an unusual presentation of this anomaly in a prepubertal girl. CASE: An 11-year-old prepubertal girl presented with recurrent urinary tract infection, pyuria, and right-sided renal agenesis. The findings of perineal inspection, ultrasonography, and magnetic resonance imaging were consistent with a distal vaginal agenesis with pyometrocolpos. Discharging pyometrocolpos with dissection of the atretic portion and a pull-through vaginoplasty were performed...

BACKGROUND: Though endovascular therapy (EVT) is increasingly applied in the treatment of intracranial vascular lesions, little is known about the effect of EVT on post-procedure headache. We aimed to investigate the prevalence of headache in patients who have undergone EVT for cerebral arteriovenous malformations (AVMs) and aneurysms. METHODS: A total of 324 patients underwent EVT treatment for aneurysms and AVMs at the Danish National Hospital from January 2012 to December 2014...

Trigeminal-cardiac reflex (TCR) from stimulation of sensory branches of trigeminal nerve can lead to hemodynamic instability. This phenomenon has been described during ophthalmologic, craniofacial, and skull base surgeries. TCR has been rarely reported with endovascular onyx embolization of dural Arteriovenous fistulas (DAVF). We report a case of TCR during endovascular Onyx embolization of an arteriovenous malformation (AVM). A 16-year-old boy presented with a large cerebellar AVM with arterial feeders from external carotid artery and posterior cerebral artery branches...

Ethmoidal dural arteriovenous fistulae are rare vascular malformations associated with a high risk of bleeding. We present a multicenter contemporary series of patients treated with microsurgical and endovascular techniques. Sixteen consecutive patients were evaluated and/or treated between 2008 and 2015 at four centers with large experience in the endovascular and surgical treatment of cerebrovascular diseases. We analyzed demographic and clinical data, risk factors for dural fistulas, treatment type, peri- and post-operative morbidity, clinical and radiological outcomes, rates of occlusion, and long-term neurological outcome...

INTRODUCTION: Vascular malformations of the spine represent rare clinical entities with profound neurological implications. Previously reported studies on management strategies for spinal dural arteriovenous fistulas (sDAVFs) were prior to the advent of modern liquid embolic agents. We present our institutional experience with endovascularly and surgically treated sDAVFs. METHODS: We performed an observational, retrospective, single-center study case series on sDAVFs treated with endovascular embolization, microsurgical occlusion, or both between 2004 and 2013...

INTRODUCTION: Endoscopic endonasal skull base surgery for vascular lesions is a controversial topic in neurosurgical practice. Concerns regarding the ability to effectively work through the relatively narrow and deep endonasal corridor and manage serious hemorrhagic complications such as inadvertent internal carotid artery (ICA) injury during endoscopic surgery (EES) are relevant sources of disagreement between neurosurgeons. Nevertheless, following careful preoperative evaluation, EES may be indicated for rare, well-selected cases, including medially-projecting paraclinoid aneurysms and cavernous malformations (CMs) located next to the ventral surface of the brainstem...

Spontaneous intracerebral hemorrhage (ICH) is a morbid disease with a high case fatality rate. Prognosis, rehemorrhage rates, and acute, clinical decision making are greatly affected by the underlying etiology of hemorrhage. This review focuses on the evaluation, diagnosis, and management of structural, macrovascular lesions presenting with ICH, including ruptured aneurysms, brain arteriovenous malformations, cranial dural arteriovenous fistulas, and cerebral cavernous malformations.

Intracranial dural arteriovenous fistulae (DAVF) are pathologic arteriovenous shunts between meningeal arteries and dural venous sinuses or veins. They account for approximately 10% to 15% of all intracranial vascular malformations and are most common in middle-aged patients. DAVF are the most common vascular cause of pulsatile tinnitus. Digital subtraction angiography remains the gold standard for diagnosing these lesions. The pattern of venous drainage determines the type of DAVF and their risk for hemorrhage...

BACKGROUND: Superficial siderosis (SS) is the occult deposition of hemosiderin within the cerebral cortex due to repeat microhemorrhages within the central nervous system. The collection of hemosiderin within the pia and superficial cortical surface can lead to injury to the nervous tissue. The most common presentation is occult sensorineural hearing loss although many patients have been misdiagnosed with diseases such as multiple sclerosis and amyotrophic lateral sclerosis before being diagnosed with SS...

Spinal dural arteriovenous fistulas (SDAVFs) are the most common type of spinal arteriovenous malformations, and microsurgical ligation is the treatment modality most frequently used for these lesions. Developments in endoscopic techniques have made endoscopy an even less invasive alternative to routine microsurgical approaches in spine surgery, but endoscopic management of SDAVF or other intradural spinal lesions has not been reported to date. The authors describe the use of a microscope-assisted endoscopic interlaminar approach for the ligation of the proximal draining vein of an L-1 SDAVF in a 58-year-old man...
