Presentation Transcript

  1. Cerebrovascular Anatomy M. Christopher Wallace M.D. The Toronto Western Hospital, University Health Network University of Toronto Postgraduate Lecture Series Division of Neurosurgery Friday October 6, 2000

  2. Collateral Circulation • Circle of Willis • Variation • Leptomeningeal Collateral

  3. Cerebral Autoregulation • Maintenance of blood flow during variation in blood pressure • Change in blood flow related to metabolic activity

  4. Mechanism for Cerebral Autoregulation? • Myogenic • Neurogenic • Metabolic

  5. Measurement of Cerebral Blood Flow • Seymour Kety • Delivery of blood flow to given wt of brain per time period • 50ml/100grams/minute Brain takes 12-15% of cardiac output

  6. Internal Carotid Artery • Divisions: cervical, petrous, cavernous, infraclinoid, supraclinoid • Branches: meningohypophyseal trunk • dorsal meningeal artery, tentorial artery, inferior hypophyseal • artery of the inferior cavernous sinus • capsular arteries of McConnell

  7. Internal Carotid Artery

  8. Internal Carotid Artery • Supraclinoid • Branches • Ophthalmic • Posterior communicating • Anterior choroidal Bifurcation

  9. Middle Cerebral Artery • Variation • Divisions (M1-M4) • Lenticulostriate arteries • medial • lateral • putamen, caudate, sup internal capsule

  10. Anterior Cerebral Artery • Variation • Divisions (A1-A4) • Anterior communicating artery • Lamina terminalis, septal region, fornix, preoptic/hypothalamus Recurrent artery of Heubner Anterior putamen, pallidum and internal capsule
