  • Abstract
  • Look Inside

Five cases of a persistent primitive olfactory artery are reported. The anomalous artery coursed antero-medially along the ipsilateral olfactory nerve and made a hairpin turn, supplying the circulation of theanterior cerebral artery. It was proposed that a primitive embryonic olfactory artery had remained as thisartery. A cerebral aneurysm was located at the hairpin curve of the artery. Hemodynamic stress is consi-dered to have an important role in aneurysm formation. Any aneurysm occurring at an artery should beconsidered for surgical treatment.
