Bilateral extracranial-intracranial (EC-IC) bypass-grafting of the cerebral circulation is uncommon. We report a case of anterior cerebral artery EC-IC bypass using the thoracodorsal axis artery-graft. The bifurcation of the thoracodorsal axis allows bypass of both anterior hemispheres, while matching appropriate small-vessel dimensions.
