Unilateral interhemispheric keyhole approach for anterior cerebral artery
Occurrence and mechanisms of occlusion of the anterior cerebral artery

Studies [18,19] which investigated hemodynamic ability of the Willis circle found that anterior cerebral artery
with recorded diameter of 0.
Blood flow in the anterior cerebral artery
from both sides was not subject to location detection.
The sound waves penetrate through the skull, pass through brain tissue and are reflected from the middle cerebral artery, the anterior cerebral artery
and the posterior cerebral artery.
After the ICA's second branch, the anterior cerebral artery
, it is called the middle cerebral artery.
There was evidence of vasospasm of the anterior cerebral artery
complex, and he deteriorated clinically with evidence of symptomatic delayed ischemic neurological deficit (DIND) 3 days after surgery (8 days after SAH).
Features that tend to make cardioembolic stroke less likely include significant cerebral atherosclerosis, stepwise progression of the neurologic deficit within a finite period of time, vascular distribution such as entire internal carotid artery territory with combined middle cerebral artery and anterior cerebral artery
involvement or watershed distribution, and premonitory transient isehemic attacks.
Compromise of the anterior cerebral artery
, which supplies the medial surfaces of frontal and parietal lobes and part of the cingulate gyrus, may result in confusion, personality changes, incontinence, and contralateral motor or sensory loss with the lower extremity commonly more affected than the upper extremity (Cammeyer & Appledorn, 1996; Hickey, 1997) (see Table 1).
Type A: Unilateral ICA agenesis; flow into the ipsilateral anterior cerebral artery
(ACA) via the anterior communicating artery (AComm), and flow into the ipsilateral middle cerebral artery (MCA) via flow through the ipsilateral posterior communicating artery (PComm).
Their most frequent location is the anterior cerebral artery
(ACA)--anterior communicating artery (AComA) complex (Monroy-Sosa et al.
This "competes" in size with the frontal polar branch of the anterior cerebral artery
Anterior cerebral artery
areas were susceptible to the effect of cross flow from the opposite side.
Fu et al2425 concluded that MCA and anterior cerebral artery
(ACA) PI were both significantly lower in the brain-sparing flow group (n=8) during basal conditions p (or =0.
