Risk Stratification of Cardiovascular Events in Very Elderly Patients with Known or Suspected Coronary Artery Disease Who had Normal Single-photon Emission Computed Tomographic Myocardial Perfusion Imaging Findings.
Conclusion The MCV event rate was high in very elderly patients despite their normal SPECT MPI findings at baseline. Therefore, very elderly patients with multivariate risks should be carefully followed to avoid a poor prognosis. PMID: 31366795 [PubMed - as supplied by publisher]

Quantitative evaluation using single-photon emission computed tomography with acetazolamide is reliable for preoperative evaluation before cardiac surgery in severe carotid intracranial artery stenotic and/or occlusive disease: a case report
Severe carotid and intracranial artery stenosis disease (CIAD) is major risk for perioperative stroke in coronary artery bypass grafting. Then, preoperative risk assessment is quite important.

Detection of Crossed Cerebellar Diaschisis by Intravoxel Incoherent Motion MR Imaging in Subacute Ischemic Stroke.
Abstract Intravoxel incoherent motion has received extensive attention in brain studies for its potential as a non-invasive magnetic resonance perfusion method. However, studies on intravoxel incoherent motion imaging and crossed cerebellar diaschisis detection are relatively scarce. The aim of our study was to evaluate the feasibility of using intravoxel incoherent motion imaging in crossed cerebellar diaschisis diagnosis in subacute ischemic stroke patients by comparing results from intravoxel incoherent motion imaging, single-photon emission computed tomography, and arterial spin-labeling perfusion methods. In ...

Superficial temporal artery-middle cerebral artery anastomosis patency correlates with cerebrovascular reserve in adult moyamoya syndrome patients.
CONCLUSION: Our data suggest that improvement in cerebral perfusion and CVR depends on flow in the STA-MCA anastomosis in patients with Moyamoya syndrome. Systematic long-term follow-up of anastomosis flow, brain perfusion and CVR improves quantification of the benefit of STA-MCA anastomosis in terms of disease progression.

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Frontal dynamic activity as a predictor of cognitive dysfunction after pontine ischemia.
CONCLUSIONSThis suggested that hyper-frontal activity might contribute to compensation for cognitive dysfunction after pontine ischemia and that recovery from the cognitive deficits is attributable to frontal activity. PMID: 31006695 [PubMed - in process]

Anterior Choroidal Artery Infarction Evaluated with 123I-Imp Single-Photon Emission Computed Tomography and 7 Tesla Magnetic Resonance Imaging
Anterior choroidal artery (AchA) infarction remains a challenging diagnosis although it was first described almost 100 years prior. N-isopropyl-p-[123I]-iodoamphetamine single-photon emission computed tomography (123I-IMP SPECT) and 7 Tesla magnetic resonance angiography (7T-MRA) are not routinely performed in cases of AchA infarction. Therefore, the application of 123I-IMP SPECT and 7T-MRA for AchA infarction has not been reported previously. A 67-year-old man presented with disturbed consciousness, gaze preference to the left, aphasia, right homonymous hemianopia, and right hemiparesis.

Progressive Cerebral Ischemia and Intracerebral Hemorrhage after Indirect Revascularization for a Patient with Cerebral Proliferative Angiopathy
We previously reported a patient with cerebral proliferative angiopathy (CPA) who showed cerebral ischemia in resting and acetazolamide-stressed N-isopropyl-p-[123I] iodoamphetamine single-photon emission computed tomography (123I-IMP-SPECT). At onset, the patient was treated conservatively. However, during the 2 years following initial onset, his hemiparesis and aphasia had gradually aggravated and his IQ scores were markedly decreased. MRI revealed progressive vascular proliferation and brain atrophy.

A functional evaluation of cerebral perfusion for coronary artery bypass grafting patients
AbstractWe evaluate the utility of providing a pulsatile blood flow by applying off-pump coronary artery bypass grafting (CABG) or intra-aortic balloon pumping (IABP) with conventional CABG to prevent perioperative stroke in patients with cerebral hypoperfusion on single-photon emission-computed tomography (SPECT). A total of 286 patients underwent isolated CABG with a cerebral magnetic resonance angiography (MRA) evaluation between 2006 and 2015. Seventy-five had significant stenosis and/or occlusion of craniocervical vessels; the other 211 had no significant stenosis. Cerebral SPECT was performed for 49 (SPECT group) of ...

Migrainous Infarction in a Patient With Sporadic Hemiplegic Migraine and Cystic Fibrosis: A 99mTc-HMPAO Brain SPECT Study.
We describe the case of a patient with CF, who had a migrainous stroke during an SHM attack. A 32-year-old Caucasian male was diagnosed with CF, with heterozygotic delta F508/unknown CFTR mutation. The patient experiences bouts of coughing sometimes triggering SHM attacks with visual phosphenes, aphasia, right-sided paresthesia, and hemiparesis. He had a 48-hour hemiparesis triggered by a bout of coughing with hemoptysis, loss of consciousness, and severe hypoxia-hypercapnia. MRI demonstrated transient diffusion hyperintensity in the left frontal-parietal-occipital regions resulting in a permanent infarction in the primary...

Hypothesis: Presymptomatic treatment of Sturge-Weber Syndrome With Aspirin and Antiepileptic Drugs May Delay Seizure Onset
Sturge-Weber Syndrome (SWS) is a neurocutaneous disorder caused by a somatic mosaic mutation in GNAQ.1 SWS brain involvement causes seizures, stroke-like episodes and/or neurological deficits such as hemiparesis and intellectual disability. Seventy-five percent of infants with SWS will develop seizures within the first year of life.2 Those with more severe epilepsy experience greater cognitive deficits and intellectual disability.3 There is ictal single-photon emission computed tomography evidence that, in SWS, the seizures themselves may contribute to the brain injury due to an abnormal hemodynamic response.

Endothelial Dysfunction and Platelet Activation in Major Depressive Disorder: Association with Brain Perfusion Abnormalities
Conclusions: Our data confirmed increased rates of endothelial damage and platelet activation in non-treated MDD patients. Furthermore, we found a positive association between regional brain perfusion and platelet activation. Together, our observations showed impairment of two fundamental hemostatic components, platelets and endothelial cells, in MDD patients, which may explain not only the increased risk of systemic vascular complications but also the association with the brain vasculature. These findings may allow to explore new treatments aimed at protecting the endothelium and targeting platelet activation, as a compre...
