  • Summary

    Moyamoya disease (MMD) is a cerebrovascular disorder characterised by progressive stenosis of the terminal portion of the internal carotid artery (ICA). The perforating arteries in the basal ganglia and thalamus markedly dilate and serve as an important collateral circulation, known as “Moyamoya” vessels. The clinical presentations of MMD include TIA, ischemic strokes, haemorrhagic strokes, seizures, headaches, and cognitive impairments. We present a 26-year old female patient that was examined due to headaches. For eight months, she had been admitted daily into the emergency hospital due to acute, unbearable headaches, which woke her up from her sleep. The MRI showed abnormalities suspicious for Moyamoya disease, which were confirmed with angiography

  • We reported a case of ischaemic stroke with moyamoya disease with simultaneous occurrence of patent foramen ovale. The patient underwent percutaneous closure of patent foramen ovale and was scheduled for follow-up.

  • Summary

    Moyamoya disease is a cerebrovasculopathy of unknown etiology characterized by chronic progressive stenosis of the arteries of the circle of Willis. An extensive collateralized circulation forms, giving rise to the smoky appearance seen on cerebral angiography (moyamoya is Japanese for “puff of smoke”). Primary clinical features of moyamoya disease, especially in children, are related to cerebral ischemia and include transient ischemic attacks and stroke. The goals of treatment are primarily to restore blood flow to the affected areas, either by direct or indirect bypass, as there is no curative treatment for moyamoya disease. This chapter details the perioperative management of a patient with coexisting morbidities of moyamoya disease, coarctation of the aorta, and pulmonary hypertension, discussing the concerns related to each and their considerations in developing an anesthetic management plan.

  • Unilateral sudden hearing loss as the first presenting symptom of moyamoya disease

  • Journal:
    The Journal of Laryngology & Otology / Volume 127 / Issue 2 / February 2013

  • Objective:

    We describe a rare case of sudden onset of unilateral sensorineural hearing loss occurring as the first symptom of moyamoya disease, which is characterised by progressive stenosis of the intracranial internal carotid arteries and their proximal anterior cerebral arteries and middle cerebral arteries.

    Method:

    Case report and review of the world literature regarding moyamoya disease with hearing loss.

    Results:

    The reported patient had moyamoya disease that initially presented as sudden, unilateral sensorineural hearing loss. Magnetic resonance imaging showed occlusion of the anterior cerebral, middle cerebral and distal internal carotid arteries bilaterally. The possible mechanism of this patient's sudden sensorineural hearing loss may have been vascular occlusion resulting from thrombotic narrowing or blockage by plaque.

    Conclusion:

    The described patient represents the first reported case of sudden onset, unilateral sensorineural hearing loss occurring as the first symptom of moyamoya disease. The possibility of a vascular lesion such as moyamoya disease should be considered in patients with sudden sensorineural hearing loss, especially children, young adults and Asian patients. Due to this disease's poor outcome, early diagnosis and treatment are important to prevent stroke.

  • Summary

    This chapter outlines some characteristics of vascular dementia (VaD) related to large-vessel diseases in terms of pathology, pathogenesis, and clinical aspects. Large-vessel VaD is characterized by a step-wise cognitive deterioration, focal signs and symptoms which are the result of repeated ischemic strokes. The chapter reviews some of large-vessel diseases such as atherosclerosis, arterial dissection, angiitis, moyamoya disease, and intracranial arterial dolichoectasia. The pathogenesis of large-vessel VaD is complex and to some extent remains a matter of investigation. Efforts in defining diagnostic criteria are made in order to characterize patterns of brain infarction from which it is reliable to deduce the presence of dementia. Some of the most important pathophysiological mechanisms and factors implicated in large-vessel VaD are volume of lesions, number of lesions, location of lesions, and coexistence of other brain pathologies, particularly Alzheimer's disease (AD).

  • Moyamoya disease in a patient with schizophrenia

  • We present the case of a 23-year-old Vietnamese male with a 2-year history of a psychotic illness marked by prominent negative symptoms, fatuousness and disturbed behavior. Neuroimaging revealed a prominent vascular flow void affecting the middle and anterior cerebral arteries, with associated increased collateral supply to the frontal cortex, consistent with Moyamoya disease. Neurological examination was unremarkable; however, neuropsychological assessment revealed significant executive dysfunction, including stimulus-driven behavior. Whilst the diagnosis of schizophrenia and Moyamoya disease may be coincidental, an interaction between the 2 diseases may have led to some of the atypical features of this case, including prominent executive dysfunction and marked sensitivity to psychotropic medication. We discuss the nature of possible interactions between the 2 conditions. This case also highlights the importance of re-evaluating patients with atypical or treatment-resistant psychoses for cerebral pathology. (JINS, 2003, 9, 806–810.)
