Arterial disruption during brain surgery can cause devastating injuries to wide expanses of white and grey matter far beyond the tumor resection cavity. Such damage may occur as a result of disrupting blood flow through "en passage" arteries. Identification of these arteries is critical to prevent unforeseen neurologic sequelae during brain tumor resection. In this study, we discuss one such artery, termed the artery of aphasia (AoA), which when disrupted can lead to receptive and expressive language deficits.

The superficial temporal artery-to-middle cerebral artery (STA-MCA) bypass is the most common bypass for augmenting or restoring cerebral blood flow. While the single barrel (SB) STA-MCA bypass is suf...
In BriefThe authors demonstrated that a greater degree of parent artery asymmetry for middle cerebral artery (MCA) aneurysms is associated with high-risk features. They also found that the presence of...
Decompressive hemicraniectomy (DH) is the mainstay of treatment for malignant middle cerebral artery infarction (MMI). Although this operation significantly reduces mortality and improves functional o...
During intracranial tumor resection, the delayed kinking of a major encased vessel has never been described in literature. We present a case which required urgent endovascular treatment performed thro...
The cerebral arterial blood volume changes (∆CBV) during a single cardiac cycle can be estimated using transcranial Doppler ultrasonography (TCD) by assuming pulsatile blood inflow, constant, and pu...
The aim of the research was to evaluate independent risk factors for the presence of middle cerebral artery aneurysm. Hemodynamic factors play the most important role in rupture aneurysm a...
The purpose of this study is to determine if patients with malignant middle cerebral artery infarction have a better clinical outcome after early decompressive surgery compared to standard...
The primary endpoint of our study is to determine whether neurological symptoms (aphasia, paresis, loss of consciousness, numbness) occur after clamping the internal carotid artery, and if...
The safety and efficacy of MK0724 will be assessed in patients with acute middle cerebral artery stroke using the Action Reach Arm Test (ARAT). This test allows measurement of a specific f...
Hypothesis: Stimulation of the SPG at low frequencies (20 Hz)is believed to cause a physiological parasympathetic upregulation which increases mean velocity in middle cerebral artery (VMC...
A polygonal anastomosis at the base of the brain formed by the internal carotid (CAROTID ARTERY, INTERNAL), proximal parts of the anterior, middle, and posterior cerebral arteries (ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; POSTERIOR CEREBRAL ARTERY), the anterior communicating artery and the posterior communicating arteries.
Artery formed by the bifurcation of the BASILAR ARTERY. Branches of the posterior cerebral artery supply portions of the OCCIPITAL LOBE; PARIETAL LOBE; inferior temporal gyrus, brainstem, and CHOROID PLEXUS.
NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.
A receptive visual aphasia characterized by the loss of a previously possessed ability to comprehend the meaning or significance of handwritten words, despite intact vision. This condition may be associated with posterior cerebral artery infarction (INFARCTION, POSTERIOR CEREBRAL ARTERY) and other BRAIN DISEASES.
Pathological conditions of intracranial ARTERIES supplying the CEREBRUM. These diseases often are due to abnormalities or pathological processes in the ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; and POSTERIOR CEREBRAL ARTERY.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
