Abstract

The use of detachable coils in the treatment of intracranial aneurysms continues to evolve since its introduction in 1991 [1-5]. Although not well described in the literature, technical considerations in gaining and maintaining access to intracranial aneurysms play a pivotal role in any successful endovascular treatment. Tortuosity and looping of the cervical internal carotid artery (ICA) is one problem occasionally encountered. These unusual loops, in addition to the normal turns of the carotid siphon result in less control of the microcatheter tip. This problem culminated in this case where an ophthalmic origin carotid aneurysm could not be successfully treated from the standard femoral approach due to the presence of multiple ICA turns, with the presence of a proximal cervical ICA turn being particularly bothersome. This problem was circumvented by use of direct surgical access to the cervical ICA above the cervical ICA turn, allowing for successful endovascular aneurysm treatment with detachable coils.
