“…Absence of an ICA is associated with collateral flow to the involved hemisphere [1,2,3,4,5,6,7,8]. Firstly, the collateral flow can involve arteries which are normally present in adulthood.…”

“…Usually they have no neurological deficit due to a good collateral blood supply to the affected side [4,6]. In cases of insufficient collateral flow a congenital absence of the ICA can lead to a cerebral hemiatrophy [5]. Clinically important is the increased prevalence of intracerebral aneurysms in patients with congenital absence of an ICA, which may be as high as 24±34 %.…”

IntroductionCongenital absence of an internal carotid artery (ICA) and the basilar artery (BA) are rare anomalies [1,2,3,4,5,6,7,8]. A persistent trigeminal artery (TGA) is the most common carotid-vertebrobasilar anastomosis and serves in our case as a collateral vessel [6,7,8,9,10,11].

Congenital absence of the internal carotid artery and the basilar artery with persistent trigeminal artery associated with coarctation of the aorta

We report a case of congenital absence of the cervical and petrous part of the left internal carotid artery, the middle and proximal part of the basilar artery, and the V4 segment of the left vertebral artery associated with a left persistent trigeminal artery and a coarctation of the aorta. The left cerebral vessels are supplied via the anterior communicating artery and the left persistent trigeminal artery. The coexisting coarctation of the aorta led to a subclavian steal phenomenon. The alteration of the cerebral hemodynamics has to be taken in consideration when performing cerebral angiography and surgical correction in such a case.

“…A vascular cause of cerebral hemiatrophy (hypoplasia), first proposed in 1860 was confirmed in later studies 7,8,9 . It was proposed that a vascular anomaly occurring in very early gestation (five or six weeks) may result in a major defect in brain development whereas those occurring later may produce more localized lesions 8 .…”

“…Agenesis, aplasia, and hypoplasia of the internal carotid artery (ICA) are rare anomalies [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]. When the ICA is congenitally absent, collateral circulation develops through the circle of Willis from the basilar artery (BA) and the opposite ICA to supply the involved hemisphere.…”

Congenital absence of the unilateral internal carotid artery (ICA) was found in a patient during MR imaging examination for right trigeminal neuralgia. Magnetic resonance angiography showed complete absence of the right ICA and a large tortuous basilar artery (BA). The source images revealed a deformed right trigeminal nerve resulting from compression by the BA. Computed tomography of the skull base showed absence of the right carotid canal, suggesting agenesis of the right ICA. Longstanding hemodynamic stress may have caused the BA to become extremely tortuous, resulting in the trigeminal neuralgia.
