“…10) Ruptured aneurysms are usually located in AComA (51%) and in ACA (19%) and 12.5% had multiple aneurysms. Majority of the previous reported aneurysms were locate in the ACA-AComA complex and no dissecting aneurysm in the A1 segment, as in the present case, has been reported.…”

“…The 68% of the cases were predominant to the right side and 19% were bilateral, though the reason is unknown. 10) Wong et al classified the infraoptic course ACA cases into four types according to the status of the ipsilateral and contralateral A1 segment. 16) In Type I, the ipsilateral A1 segment is normal.…”

“…Though the embryogenesis is still controversial, it is hypothesized that anomalies in the arterial ring around the optic nerve are related to this variation. 10) These may include (1) persistence of an anastomotic loop of the primitive dorsal and ventral OphAs which disappear as OphA is formed, (2) enlargement of a small anastomosis among the superior hypophyseal branch of ICA, the prechiasmatic branch of OphA, and the chiasmal branch of ACA, and (3) persistence of an anastomosis between the primitive maxillary and olfactory arteries. The primitive maxillary and olfactory arteries appear in the earliest fetus stage, 19) and Wong et al indicated that the arterial ring consisting this two arteries can explain the origin of all types infraoptic course ACA.…”

“…7–10) Infraoptic course ACA is considered as a persistence of embryonal arteries. Although cerebral aneurysms associated with infraoptic course ACA have been reported, 10) there has been no case of dissecting aneurysm in the A1 segment associated with infraoptic course ACA. In this article, we present the clinical course of this patient and discuss treatment strategy as well as the embryogenesis of this anomalous artery.…”

A 48-year-old man presented a subarachnoid hemorrhage caused by a rupture of a dissecting aneurysm at the proximal segment (A1 segment) of the right anterior cerebral artery (ACA). He also had an anomalous artery named infraoptic course ACA and an agenesis of the contralateral ACA A1 segment. Balloon occlusion test at the bifurcation of the right internal carotid artery demonstrated that the distal segments of the bilateral ACAs were perfused through the infraoptic course ACA. Therefore, we surgically trapped the A1 segment including the aneurysm. The patient got discharged without any neurological deficit. Natural course of ACA dissecting aneurysms is unclear because of rarity of the disease and treatment strategy is still controversial. Most of the dissecting aneurysms in the A1 segment are surgically treated, because they often present with massive hemorrhage and poor prognosis. In the present case, the contralateral A1 segment was absent but trapping of the dissecting aneurysm could be achieved without vascular reconstruction (e.g., bypass surgery) because of the presence of the infraoptic course ACA.

“…There are also other presentations, such as acute subarachnoid hemorrhage, consciousness disturbance, sixth cranial nerve palsy, different visual field defects, diplopia, hemiparesis, and symptoms suggestive of vertebrobasilar insufficiency. Cerebrovascular anomalies of the persistent trigeminal artery include an infraoptic course of the A1 segment of the anterior cerebral artery (Turkoglu et al 2011), absence of the common carotid artery (Rossitti and Raininko 2001), absence of internal carotid artery (Hattori et al 1998), an occluded internal carotid artery, hypoplastic basilar and vertebral arteries, bilateral occlusion of the vertebral artery, and a primitive otic artery (Azab et al 2012). Davis et al (1956) first reported an aneurysm of the persistent trigeminal artery.…”
