'Artery of Percheron' is a rare variation in blood supply in which a solitary arterial trunk arises from one of the proximal segments of the posterior cerebral arteries and supplies the paramedian thalami bilaterally. A young patient (in their early 30s) who presented with sudden onset of visual disturbance and speech difficulties is reported. A review of literature from 1981 to 2009 and review of the most widely reported clinical signs and symptoms are provided.

The Outreach distal access catheter (DAC; Concentric Medical, Mountain View, California, USA) has been designed to assist the Merci device (Concentric Medical) with clot retrieval in the setting of acute stroke. Its application for coil embolization of intracranial aneurysms was investigated. ⋯ For smaller or distal intracranial aneurysms with difficult access, use of the DAC as an additional platform in close proximity to the target aneurysm subjectively enhanced microcatheter control and safety.
