ABSTRACT

This paper presents 12 cases of the persistent trigeminal artery (PTA) concurrent with cerebrovascular diseases. In 7 patients, PTA was accompanied by cerebral aneurysms, 2 had prior subarachnoidal hemorrhage (SAH) of unknown origin, other 2 patients had acute transient ischemic attacks. In one case, PTA was concomitant with arteriovenous malformation. Clinical features and hemodynamic variants of PTA are described. Diagnostic modalities and surgical management of combinations of PTA and aneurysms in the presence of SAH are discussed.
