The continuation of the cranial branch of the primitive internal carotid artery is called the primitive olfactory artery (POℓA). 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 POℓA (PPOℓA) in Serbian population after retrospective analysis of digital images of 200 fetal and 269 adult cases. This PPOℓA 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 PPOℓA is usually asymptomatic in Serbian population.
原始颈内动脉颅内部的延续称为原始嗅动脉（POℓA）。之所以取这个名字，是因为它主要与发育中的鼻区有关。在对 200 例胎儿和 269 例成人病例的数字图像进行回顾性分析后，我们在塞尔维亚人群中报告了两例新的永存原始嗅动脉（PPOℓA）病例。该 PPOℓA 起源于大脑前动脉前交通段（A1），沿嗅束走行，在两名成年男性的大脑中动脉内侧半球转弯。一些血管变异（A1 管腔开窗和胼胝体正中动脉）与该永存血管有关。根据我们之前和最近的两例病例均未发现动脉瘤的事实，我们认为 PPOℓA 在塞尔维亚人群中通常无症状。
