The left A1 segment was not visualized while the left A2 segment was supplied by a patent anterior communicating
In our experience, ETA's contraindications may include tumors that extend to cerebral ventricles, encase the vital vessels (such as the anterior communicating
artery and the intracavernous ICA), and subpially diffuse or extend beyond the optic nerves.
Some studies do not describe specific variants of the anterior communicating
artery and group them as "fenestrations of the AComA", which limits the anatomical knowledge of this vessel (Kayembe et al, 1984; Dimmick & Faulder, 2009; Ferre et al, 2013; Hashemi et al, 2013; Iqbal, 2013; Kardile et al.
Collateralization with the opposite internal carotid artery (ICA) is conducted via anterior collateral segment of CoW (made of A1 segments of anterior cerebral artery--ACA and anterior communicating
About the consequences of callosotomy surgery, many complications may be listed like an occiptal and cingular contusion due to a posterior interhemispheric approach, ischemia in the pericallosal territory in the anterior communicating
artery territory, bilateral mesiofrontal damage and venous infarct from bridging vein damage, so that all of them are transient or permanent (20).
Aneurysms: A Trial of Conservative and Surgical Treatment.
Two adult specimens have showed double anterior communicating
Two intracranial aneurysms were found, one at the anterior communicating
artery (Acom), the other at the carotid T.
The CT-angiography (CTA) and digital subtraction angiography (DSA) showed multiple cerebral aneurysms at the site of bifurcation of right middle cerebral artery, A1 segment of left anterior cerebral artery, anterior communicating
artery, left posterior communicating artery, and basilar artery bifurcation (Figure 1).
In general, the anterior communicating
artery and posterior circulation aneurysms cause such IVHs.
Other less common sites include the anterior communicating
artery and internal carotid artery.
The anterior cerebral arteries of the two hemispheres are joined together by the anterior communicating
