Outline • Sectional imaging of the brain • Anatomy • Detecting pathology • Common vascular surgery operations
Sectional anatomy :Brain • Cerebrum • Cerebellum • Brainstem
Cerebrum • 4 layers • Ventricles • Deep nuclei • White matter • Cortex
Detecting pathology • 5 check areas • Extra-axial – Bleeds + Collections – Extradural, subdural,and subarachnoid, meningiomas • Intraxial – Masses, oedema, haemorrhage • Basal cisterns and ventricles – Mass effect (midline shift, compressed ventricles), Hydrocephalus, occult subarachnoid blood • Blood vessels • Bones – Fractures, acoustic neuromas
Common operations • Common carotid artery • Brachial • Radial • Femoral • Popliteal
Common carotid a • Dangers • Layers
Brachial a • Dangers • Layers
Radial a • Dangers • Layers
Femoral • Dangers • Layers
