objective(s):the present study investigated the effect of long-term mild cerebral hypoperfusion induced by permanent unilateral (right) common carotid artery occlusion (uco) on the dorsal hippocampal neurons in rats. materials and methods:sixty four male sprague-dawley rats aged 4 months were divided into two groups of sham and uco. these two groups were further divided into 4 sets of histopath...

A 10-year-old boy presented with left hemiplegia and facial droop after prolonged seizure activity overnight. MRI showed hypoperfusion involving the right cerebral hemisphere. Susceptibility-weighted imaging (SWI) demonstrated prominence of ipsilateral draining veins, indicating increased deoxyhemoglobin content within the hypoperfused territory (figure). There was no acute infarct. Weakness im...

yncope is defined as loss of consciousness and postural tone due to transient global cerebral hypoperfusion. Although it may also manifest as transient loss of consciousness, epilepsy is not due to cerebral hypoperfusion, and its treatment differs markedly from that of syncope.1 A 66-year-old, right-handed man presented with a 11/2-year history of 2 to 3 episodes of syncope/month, usually prece...

Patients who have cerebrovascular disease and vascular insufficiency routinely have neurosurgical and nonneurosurgical procedures. Anesthetic priorities must provide a still bloodless operative field while maintaining cardiovascular stability and renal function. Patients who have symptoms or a history of cerebrovascular disease are at increased risk for stroke, cerebral hypoperfusion, and cereb...

A 76-year-old woman presented with catatonia, refusal to eat due to delusion, and visual hallucination. Single photon emission computed tomography showed remarkable occipital hypoperfusion and frontal hyperperfusion. (123)I metaiodobenzyl guanidine myocardial scintigraphy revealed decreased uptake. She was diagnosed as probable dementia with Lewy bodies (DLB). Intravenous or oral L-dopa had no ...

We present the case of a 65-year-old man with dyspnea and chest discomfort referred for dipyridamole myocardial perfusion scintigraphy. 99mTc-sestamibi cardiac gated SPECT images showed an irreversible hypoperfusion in the mid-ventricular portion of anteroseptal wall, a suspicious reversible hypoperfusion in the apical slices of inferolateral wall, and left ventricle dilatation with a ejection ...

This paper presents the case of a 17-year-old right-handed Belgian boy with developmental FAS and comorbid developmental apraxia of speech (DAS). Extensive neuropsychological and neurolinguistic investigations demonstrated a normal IQ but impaired planning (visuo-constructional dyspraxia). A Tc-99m-ECD SPECT revealed a significant hypoperfusion in the prefrontal and medial frontal regions, as w...
