The anterior cerebral artery along with the chile middle cerebral artery forms at the termination of the internal carotid artery. It is the smaller of the two, and arches anteromedially to pass anterior to the genu of the corpus callosum, dividing as it reviews does so into its two major branches; pericallosal and callosomarginal arteries (see below). It supplies the medial aspect of the cerebral hemispheres back to the parietal lobe. Gross anatomy, segments, the aca is divided into three segments: Branches, there are two main branching patterns of the aca. In the first the A2 gives off the callosomarginal artery (which lies in the cingulate sulcus and continues as the pericallosal artery. In this configuration, the terminal (cortical) branches are given off the callosomarginal artery. In the second configuration, the callosomarginal is absent and the terminal branches arise directly from the pericallosal.

Posterior inferior cerebellar artery - an overview ScienceDirect Topics


There was no palatal myoclonus. Cerebellar examination was normal in the limbs. There was a strong left-beating gaze-evoked nystagmus, and also there was a right-torsional beating torsional nystagmus. Positional testing was abnormal due to the ongoing nystagmus, but there was also a brief upbeating nystagmus. Headshaking provoked a very strong reversal of nystagmus. Vestibular testing elicited normal vhit, and rotatory chair testing had a normal gain/time-constant, but there was strong spontaneous nystagmus.

On seeing him about 5 months later, he was walking without aid. He had a stronger right-torsional nystgmus, that became downbeating on lateral gaze, and became much larger after gaze-holding to the side and returning to the center (i.e. There was still no palatal myoclonus. Cerebellar examination continued to be nearly normal, although a little better on the left (his nondominant side). The pupils remained smaller on the right. Comment: This is a nearly classic lmn (Wallenberg) syndrome from the general features, with a persistent torsional nystagmus, beating in a paradoxical (RT) direction. He also has a paradoxical direction of head-shaking nystagmus. There are strong influences of both gaze and gravity, but relatively little limb dysmetria.

Pica is the most common site of honing occlusion from propagating thrombus or embolism caused by injury to the third section of the vertebral artery, and Wallenberg's syndrome ischias is the most common stroke caused by chiropractic manipulation (Caplan, 1986). See also: Brainstem Strokes, right lateral medullary syndrome, acute diffusion image of patient described below. There is low blood flow on the right medulla (left side above). Reversal of spontaneous nystagmus from lb to rb on head-shaking in lmn syndrome. Case of Wallenberg's syndrome: A man in his 50's developed dizziness after a brainstem stroke, experienced 2 months ago. The stroke was due to a cardiac arrhythmia, and at one point the vertebral artery on the right was blocked. When he was seen in the office, he was in a wheelchair, and his speech was hoarse. His right pupil was smaller but both reacted.

Prognosis is generally quite good with full or near full recovery expected at 6 months. Diagnosis is generally via mri (see below). Ct-angiography with 3D reconstruction has gotten good enough in recent years to be helpful too. Abr testing is often duizeligheid abnormal in persons with central Horner's syndrome (Faught and Oh, 1985 but as the lesion in Wallenberg syndrome is usually below the auditory connections, horners due to wallenbergs are not generally associated with abnormal abr. Arrangment of pica as a branch of the vertebral artery. Inferior cerebellar territory stroke following a vertebral artery dissection (right side of picture). Pica may arise from the vertebral artery (the usual case or as a separate branch of the basilar artery. Because of the far more common origin from the vertebral artery, most "pica" syndrome strokes actually are due to vertebral artery occlusion (Kim 2003). Cardiac embolism causes only 5 of these strokes, while dissection causes 15 (Kim, 2003).


For vertical saccades upward or downward, eyes always move to the right, which is contralateral to the side of the stroke (on the left). This is contrapulsion (see below). We know it is not due to the head being tilted, because in that case, the eyes would not always go the same direction. There also may be saccadic dysmetria (overshoot saccadic pulsion (pulling stress of the eye during vertical saccades toward the side of lesion - called ipsipulsion). Rarely, the eyes go towards the opposite side of the lesion (called contrapulsion). (Kaski et al, 2012). Because the eyes can go either way, ipsi or contra, the localizing significance of pulsion is not teriffic.

Pica stroke -causing vertigo and bruine hearing loss. Hain, md, page last modified: november 20, 2017. The pica syndrome is also known as "lateral medullary syndrome or "Wallenberg's syndrome after Wallenberg's description in 1895. This is the most common brainstem stroke. It is typified by vertigo, ipsilateral hemiataxia, dysarthria, ptosis and miosis. Most patients with this stroke recover very well and often resume their previous activities (Nelles et al, 1998). Patients often have a horner's syndrome (unilateral ptosis, miosis and facial anhidrosis). Medullary infarct from left vertebral artery dissection (L dorsolateral medulla) associated with "contrapulsion".
