  2. F. Signorelli, F. Scholtes, N. McLaughlin, M.W. Bojanowski – Dural Branch from ACA Dural arteries • 3 systems (external carotid, internal carotid, vertebrobasilar) • Anterior fossa • Anterior ethmoidal (IC: opthalmic) • Posterior ethmoidal (IC: ophtalmic) • Superficial recurrent branch (IC: opthalmic; anastomosis with middle meningeal) • Olfactory branches from ACA (IC) • Middle meningeal, except if ophthalmic origin (EC)

  11. F. Signorelli, F. Scholtes, N. McLaughlin, M.W. Bojanowski – Dural Branch from ACA Anatomical significance • Yasargil: dural branch • from pre-bifurcation carotid to anterior clinoid process • 2 cases: origin at anterior cerebral artery (to limbus) • Lasjaunias (cited also by Martins, Rhoton): • dural olfactory branches of ACA • anastomose with ethmoidal (ant/post) • Olfactory branches: from long A2 branches (Ciolkowski) • cortical (ant./post. Orbito-frontal) • subcortical (Heubner) Yasargil MG (1984) Operative anatomy. Yasargil MG Micro- neurosurgery vol I.

  18. F. Signorelli, F. Scholtes, N. McLaughlin, M.W. Bojanowski – Dural Branch from ACA Surgical importance • Avulsion may lead to bleeding from ACA • Aneurysm surgery (papaverine) • Pre-op diagnosis interesting, especially when vessel of significant caliber
