Abstract

The continuation of the cranial branch of the primitive internal carotid artery is called the primitive olfactory artery (POA). It takes this name according to the fact that it is mainly concerned with supplying the developing nasal region. We reported two new cases of the persistent POA (PPOA) in Serbian population after retrospective analysis of digital images of 200 fetal and 269 adult cases. This PPOA originated from the precommunicating part (A1) of the right anterior cerebral artery, coursed along the olfactory tract, and turned on the medial cerebral hemisphere in both male adults. Some vascular variations (fenestration of the A1 and the median artery of the corpus callosum) were associated with this persistent vessel. According to the fact that we did not find aneurysm in our previous and two recent cases, we are of the opinion that PPOA is usually asymptomatic in Serbian population.
