J. Ogata, H. Yamanishi and H. Ishibashi-Ueda (2011) Neuropathology and Applied Neurobiology37, 40-55 Role of cerebral vessels in ischaemic injury of the brain This review discusses the pathological changes in the heart and vessels underlying brain ischaemic injury, with a major focus on atherosclerotic disease of the brain induced by lesions of the extracranial cervical and major intracranial arteries and small-vessel disease of the brain. The carotid bifurcation is the primary site for atherosclerotic changes, for which extensive clinical trials and pathological analyses on carotid endarterectomy specimens have been performed. Plaque rupture and erosion give rise to thrombus formation, which leads to brain ischaemic injury. These changes have much in common with atherosclerotic lesions of the subepicardial coronary arteries. Emboli of various types of particles are characteristics of brain ischaemic injury. Thrombi rich in fibrin and red blood cells (red thrombi) that develop in the cardiac chambers are common sources of cerebral emboli. Small-vessel disease of the brain induces fibrinoid necrosis, microaneurysm, fibrohyalinosis, lipohyalinosis and microatheroma, changes commonly associated with hypertension. The acute hypertensive small-vessel changes organize to create segmental arterial disorganization and deep small infarcts when they escape from rupture. Some specific vascular diseases responsible for brain ischaemic injury are briefly reviewed also.
