Detection of Anomalous Cervical Internal Carotid Artery Branches by Colour Duplex Ultrasound
2017, European Journal of Vascular and Endovascular SurgeryCitation Excerpt :The potential clinical implications of an ICA branch readily detectable on CDU, are documented in Table 3 and highlight that although rare, Kolbinger et al.'s31 case report and review of the literature found that there is a surprising association between a persistent proatlantal artery ICA branch and a 59% increase in intracranial cerebrovascular abnormalities including a 10% risk of having an intracranial aneurysm. Further studies support a theory that the persistence of carotid vertebrobasilar anastomoses is pathological and have an increased risk of cerebral aneurysms or compressive disorders.31,39–42 Although, Cloft et al.43 claim that the prevalence of cerebral aneurysms in this subset is no different from the general population and the associations are based solely on case reports and thus may be coincidental.

2011, Journal of NeuroradiologyCitation Excerpt :Occasionally, they may persist in adulthood. PTA is the most common carotid-basilar anastomosis, representing 85% of these primitive persistent anastomoses [1]. Usually, it originates from the ICA after its exit from the carotid canal and joins the upper third of basilar artery.
Diagnosis and surgical management of extracranial PICA aneurysms presenting through subarachnoid haemorrhage: Case report and review of the literature
2009, Clinical Neurology and NeurosurgeryCitation Excerpt :For further reference to the anatomy of the PICA's course we would refer to the excellent study of Lister et al. [24]. The variations of PICA origin have been explained with the persistence of different branches of the vertebrobasilar embryonic plexus or of the anastomotic channels connecting the vertebral system to the carotid system (trigeminal, otic, hypoglossal and proatlantal arteries) [33,34]. Aneurysms of the PICA are most common at their origin or just distal thereof and account for approximately 1% of all cerebral vasculature aneurysms [6–9].
