BACKGROUND AND PURPOSE A combined therapeutic approach has been advocated repeatedly for treatment of focal cerebral ischemia. A clinical example of combined therapy is administration of nimodipine, mannitol, dexamethasone, and barbiturates during temporary occlusion of a cerebral artery in neurovascular surgery. We have recently demonstrated outstanding neuroprotective properties of a combinat...

BACKGROUND AND PURPOSE Typewriter tinnitus, a symptom characterized by paroxysmal attacks of staccato sounds, has been thought to be caused by neurovascular compression of the cochlear nerve, but the correlation between radiologic evidence of neurovascular compression of the cochlear nerve and symptom presentation has not been thoroughly investigated. The purpose of this study was to examine wh...

Aging is the major risk factor for neurodegenerative diseases such as Alzheimer's disease, but little is known about the processes that lead to age-related decline of brain structures and function. Here we use RNA-seq in combination with high resolution histological analyses to show that aging leads to a significant deterioration of neurovascular structures including basement membrane reduction...

Cortical spreading depolarization causes a breakdown of electrochemical gradients following acute brain injury, and also elicits dynamic changes in regional cerebral blood flow that range from physiological neurovascular coupling (hyperaemia) to pathological inverse coupling (hypoperfusion). In this study, we determined whether pathological inverse neurovascular coupling occurred as a mechanism...

The trigeminal neuralgia caused by neurovascular compression is a neurosurgical pathology requiring the preoperative identification as exact as possible of the neurovascular conflict. In this case, neuroimaging is very useful, as it allows not only the determination of the neurovascular conflict of the trigeminal nerve, but also the correct indication of an adequate surgical approach.

BACKGROUND Although percutaneous trigger digit release is common, controversy exists regarding its safety. The purpose of this study was to evaluate the feasibility and safety of the neurovascular displacement by local hydraulic dilatation (LHD) during percutaneous trigger digit release. MATERIAL AND METHODS Ten cadaver hands with 50 digits were dissected in this anatomical study. The distance ...

Objective: Stroke is a kind of disease with high morbidity, high mortality and high disability rate. Since currently available drugs treating cerebral ischemia have many limitations, it is necessary to find a new treatment approaches. The emergence of neurovascular unit provides a new perspective for basic research of stroke. Methods: Summarize the literature of research data relevant on the ne...

PURPOSE To investigate, using MR imaging, neurovascular compression at the ventrolateral medulla oblongata in patients with essential hypertension. METHODS Thirty-two patients with essential hypertension (57.6 +/- 7 years of age), 6 patients with secondary hypertension (56.7 +/- 10.3 years of age), and 18 control subjects (50.5 +/- 11 years of age) were evaluated. Transaxial three-dimensional...

Introduction: The neural regulation of the microcirculation is done by the functional neurovascular unit that is composed of vascular, astroglial and neuronal cells. The neurovascular unit represents the interface between the Central Nervous System and the Vascular System. Objective: This paper reviews the literature on functional neuroimaging with a particular focus on the mechanisms of the ne...
