Abstract A case of vertebrobasilar insufficiency with bilateral homonymous hemianopsia and macular sparing is presented. A persistent trigeminal artery was the likely conduit for emboli to pass from an ulcerated carotid bifurcation to the vertebrobasilar circulation. The diagnostic and therapeutic implications in cerebrovascular disease are discussed.
