“…Conversely, damage to the medial wall of the hemisphere from anterior cerebral artery (ACA) stroke is a rare clinical phenomenon (e.g., Bogousslavsky and Regli, 1990; Kazui et al, 1993; Kumral et al, 2002; Carrera et al, 2007, for review see Brust, 1992) as are alterations in clinically detectable simple voluntary tongue movements after such injury (Critchley, 1930). However, some observations indicate that ACA stroke results in higher-order oromotor complications including speech disturbances, deficits in articulation (dysarthria) and swallowing difficulties (dysphagia) (Critchley, 1930; Bogousslavsky and Regli, 1990; Chamorro et al, 1997).…”

The corticobulbar projection to the hypoglossal nucleus was studied from the frontal, parietal, cingulate and insular cortices in the rhesus monkey using high-resolution anterograde tracers and stereology. The hypoglossal nucleus received bilateral input from the face/head region of the primary (M1), ventrolateral pre- (LPMCv), supplementary (M2), rostral cingulate (M3), and caudal cingulate (M4) motor cortices. Additional bilateral corticohypoglossal projections were found from the dorsolateral premotor cortex (LPMCd), ventrolateral proisocortical motor area (ProM), ventrolateral primary somatosensory cortex (S1), rostral insula and pregenual region of the anterior cingulate gyrus (areas 24/32). Dense terminal projections arose from the ventral region of M1, moderate projections from LPMCv and rostral part of M2, with considerably less hypoglossal projections arising from the other cortical regions. These findings demonstrate that extensive regions of the non-human primate cerebral cortex innervate the hypoglossal nucleus. The widespread and bilateral nature of this corticobulbar connection suggests recovery of tongue movement after cortical injury that compromises a subset of these areas, may occur from spared corticohypoglossal projection areas located on the lateral, as well as medial surfaces of both hemispheres. Since functional imaging studies have shown that homologous cortical areas are activated in humans during tongue movement tasks, these corticobulbar projections may exist in the human brain.

“…Anterior cerebral artery occlusions primarily affect frontal lobe function and can result in disinhibition and speech perseveration, producing primitive reflexes (e.g., grasping, sucking reflexes), altered mental status, impaired judgment, contralateral weakness (greater in legs than in arms), contralateral cortical sensory deficits, gait apraxia, and urinary incontinence.

Cerebrovascular complications are being frequently recognized in the pediatric intensive care unit in the recent few years. The epidemiology and risk factors for pediatric stroke are different from that of the adults. The incidence of ischemic stroke is almost slightly more than that of hemorrhagic stroke. The list of diagnostic causes is increasing with the availability of newer imaging modalities and laboratory tests. The diagnostic work up depends on the age of the child and the rapidity of presentation. Magnetic resonance imaging, computerized tomography and arteriography and venography are the mainstay of diagnosis and to differentiate between ischemic and hemorrhagic events. Very sophisticated molecular diagnostic tests are required in a very few patients. There are very few pediatric studies on the management of stroke. General supportive management is as important as the specific treatment. Most of the treatment guidelines and suggestions are extrapolated from the adult studies. Few guidelines are available for the use of anticoagulants and thrombolytic agents in pediatric patients. So, our objective was to review the available literature on the childhood stroke and to provide an insight into the subject for the pediatricians and critical care providers.

“…Unruptured aneurysms have been observed in 2.8% of patients investigated by magnetic resonance (MR) angiography 10. People with variations in cerebral arteries, particularly, in anterior cerebral arterial (ACA) territory are thought to be subjected to imbalance in cerebral blood flow leading to cerebrovascular pathologies, including cerebral aneurysms 11…”

“…Variations in cerebral basal arterial network have ranged from missing arterial segments to asymmetry between collateral arterial segments and the later was more common 12 13. Some of the most variant and asymmetric patterns of arteries were seen in relation to anterior cerebral and anterior communicating arterial territories 11 14. Fluctuation in arterial blood flow, and thus the blood pressure, has been observed in asymmetric A1 segments 15 16.…”

ObjectivesThe aim of this study was to establish an anatomical index for early prediction of the risk of development of aneurysms in anterior communicating arterial complex (AcomAC). The asymmetric diameter of one anterior cerebral artery (ACA) to other could alter haemodynamics and may contribute to formation of aneurysms in AcomAC and be a reliable predictor of the risk of development of aneurysms.Design and settingThis is a retrospective, observational and quantitative study, which used cerebral computed tomography angiography (CCTA) scans in South Australia.ParticipantsCCTA scans of 166 adult patients of both sexes were studied.Main outcome measuresThe internal diameters of the proximal segments of ACAs (A1s) were measured. Position and presence or absence of aneurysms in AcomAC were determined. The ratio of A1 diameters was taken as a measure of A1 asymmetry.ResultsThe ratio of diameters of A1s correlated with the occurrence of AcomAC aneurysms. The risk of development of aneurysms in AcomAC was much greater (80%, OR=47.3) when one A1 segment’s radius was at least 50% larger (ie, 2.25 times cross-sectional area) than the other.ConclusionThe general information on asymmetric A1 has been published previously. The present findings have significant contribution since the A1s asymmetry ratios have been categorised in ascending order and matched with the presence of AcomAC aneurysms. The asymmetry ratio of the A1 is a good predictor for the development of AcomAC aneurysms. Reconstruction of the asymmetric A1 could be done if the technology gets advanced.
