“…In our case, the hypoplasia of both vertebral arteries, the absence of the right ICA, and the occlusion of the left ICA make the right PPHA the exclusive feeder of the circle of Willis. Reviewing the published literature, only one definite case of PPHA as the sole supply to the brain was reported (7). More specifically in our case, a basilar bifurcation aneurysm was associated with PPHA.…”

The persistent primitive hypoglossal artery (PPHA) is the second most common persistent carotid–vertebrobasilar anastomosis, with an incidence of 0.027–0.26%. PPHAs change the hemodynamics of the carotid and vertebrobasilar system and may be associated with intracranial vascular anomalies, but basilar bifurcation aneurysms were rarely reported. We describe the first case of a PPHA as the sole supply to the brain associated with a basilar bifurcation aneurysm and review the literature. We reported a 34-year-old woman who presented with subarachnoid hemorrhage due to a ruptured basilar bifurcation aneurysm. Digital subtraction arteriogram revealed a right PPHA as the sole supply to the brain. The aneurysm was successfully clipped under intraoperative neurophysiology.
