title: [Coil embolization of a ruptured posterior cerebral artery aneurysm via the internal carotid artery and a posterior communicating artery: a case report].
abstract: A posterior cerebral artery aneurysm is a rare condition. Various surgical approaches have to be considered for operating on these aneurysms because the position of the aneurysm and the surrounding structures restrict the operative field and render the operation difficult. Recently, endovascular treatments for posterior cerebral artery aneurysms have been reported to provide a good outcome. We present a case of a ruptured posterior cerebral artery aneurysm treated with coil embolization. We adopted endovascular treatment because a large vein of Labbé was expected to restrict the operative field. The internal carotid artery and a fetal-type posterior communicating artery (PCoA) were chosen as the access route because of P1 hypoplasty, and a coaxial guiding system was used because of the tortuous access route. The aneurysm was suitably embolized using Guglielmi detachable coils (GDCs). In a case of posterior cerebral artery aneurysm, we report the usefulness of endovascular treatment performed through the internal carotid artery and a fetal-type PCoA.
