Bilateral steno-occlusive disease of the middle cerebral artery: a case report with clinical-hemodynamic mismatch CASE REPORT

چکیده
Case report: A 37-year-old man was admitted for a right MCA transient ischaemic attack. He was smoker, obese, dyslipidaemic, with previous history of heroin addiction and cured B and C hepatitis virus infections. Brain magnetic resonance and cardiac evaluation were normal. Transcranial color-coded sonography (TCCS) showed >50% proximal right MCA stenosis and distal left MCA occlusion. Treatment with aspirin and statin was started. Three months later, TCCS revealed >70% right MCA stenosis and left MCA occlusion. Selective angiography confirmed the steno-occlusive disease. Cerebrospinal fluid analysis revealed increased protein levels and a normal cell count. Corticotherapy was started, but the patient did not complied. Bilateral occlusion of MCA was noticed on TCCS, one month later, being the patient asymptomatic. Pulsed arterial spin labelling (PASL) revealed a severe decrease of cerebral blood flow in the distal part of both MCA territories.

Concurrent Stenoocclusive Disease of Intracranial and Extracranial Arteries in a Patient with Polycythemia Vera
Moyamoya disease is a stenoocclusive disease involving the intracranial carotid and proximal middle cerebral arteries. There are rarely any additional extracranial stenoses occurring concurrently with moyamoya. The pathophysiology of moyamoya remains obscure, but hematologic disorders, notably sickle-cell anemia, have been associated in some cases. We describe the novel case of polycythemia ver...
متن کاملAssessment of cortical hemodynamics by multichannel near-infrared spectroscopy in steno-occlusive disease of the middle cerebral artery.
BACKGROUND AND PURPOSE In a pilot study we evaluated near-infrared spectroscopy as to its potential benefit in monitoring patients with steno-occlusive disease of a major cerebral artery for alterations in cortical hemodynamics. METHODS Cortical maps of time-to-peak (TTP) in 10 patients unilaterally affected by severe stenosis or occlusion of the middle cerebral artery were acquired by multic...

OBJECTIVES Our purpose of this study was to assess the cerebral hemodynamic improvement with perfusion computed tomography (CT), before and after superficial temporal artery (STA) to middle cerebral artery (MCA) bypass surgery in patients with cerebrovascular steno-occlusive diseases including both moyamoya disease and nonmoyamoya steno-occlusions. MATERIALS AND METHODS Twenty-four STA-MCA by...

sites of steno-occlusive changes. This progression is slow and takes years, being compensated by the formation of thalamostriate and leptomeningeal collateral blood vessels [4] , until hemodynamic compromise requires surgical revascularization. While the natural history of MMD prior to surgery is well known, the relevance of progressive steno-occlusive changes following successful surgery is st...
متن کاملChanges in cerebral hemodynamic and cognitive parameters after external carotid-internal carotid bypass surgery in patients with severe steno-occlusive disease: a pilot study.
BACKGROUND The direct impact of external carotid-internal carotid (EC-IC) bypass surgery on cognition of patients with severe steno-occlusive disease of internal carotid (ICA) or middle cerebral artery (MCA) is unknown. In this pilot study, we evaluated changes in cerebral hemodynamic and cognition in these patients. METHODS Patients with severe steno-occlusive disease and impaired cerebral v...
