Moyamoya disease involving anterior and posterior circulation

چکیده
A 6‐year‐old female presented with sudden‐onset right‐sided hemiparesis with motor aphasia for the past 7 days. Magnetic resonance imaging of the brain [Figure 1a] revealed acute infarct in the left parietooccipital region. Magnetic resonance angiogram (MRA) [Figure 1b] and computed tomography angiogram (CTA) [Figure 2] showed narrowing of bilateral supraclinoid internal carotid arteries (ICAs), nonvisualization of bilateral middle cerebral arteries and distal part of posterior cerebral arteries (PCAs) along with extensive collateralization of vessels, creating a “puff of smoke” appearance, diagnostic of moyamoya disease.

Exacerbation of Major Artery Aneurysms after Revascularization in Patients with Moyamoya Disease: Two Case Reports
The natural history of aneurysms of the major arteries after revascularization in moyamoya disease has yet to be documented. At our institute, we treated two patients with moyamoya disease-associated aneurysms involving major arteries of the posterior cerebral circulation. The aneurysms became enlarged at an early stage after revascularization, necessitating coil embolization. Although cerebral...

The majority of clinical studies on moyamoya disease (MMD) have focused on anterior circulation. The disease involvement of posterior circulation in MMD, mainly in the posterior cerebral artery (PCA), has been mentioned since the early 1980s, and it has been repeatedly emphasized as one of the most important factors related to poor prognosis in MMD. However, its clinical features and outcome ha...
متن کاملPosterior circulation intracranial arterial occlusive disease in neurofibromatosis.
It is well known that neurofibromatosis is one apparent etiology for the type of intracranial arterial occlusive disease known as moyamoya disease [1-4]. All previously reported cases of neurofibromatosis with moyamoya disease have had involvement only of the intracranial carotid circulation (supraclinoid internal carotid artery, middle cerebral artery, anterior cerebral artery) [1 -4]. We repo...

The authors present a rare case of moyamoya disease emerged with corpus callosum hemorrhage. A 31-year-old woman suddenly complained of severe headache followed by consciousness disturbance. Radiological examinations revealed the bleeding in the splenium of corpus callosum, which was associated with intraventricular hemorrhage. On cerebral angiography, the carotid fork was severely stenotic on ...
متن کاملIntracranial Hemodynamic Changes During Adult Moyamoya Disease Progression
BACKGROUND AND PURPOSE This study evaluated the changes in blood flow velocity in the anterior and posterior intracranial circulations according to the progression of moyamoya disease in adult patients. METHODS We evaluated Suzuki's angiographic stage and mean blood flow velocity (MBFV) changes in intracranial vessels from both sides in 19 adult moyamoya patients. We then analyzed the lineari...
