SUMMARY: The distal medial striate artery is part of the brain circulation, born from the anterior cerebral artery generally at the level of the anterior communicating
artery, although according to different studies its origin varies, being thus difficult to determine with accuracy.
The use of shunt was according to the indications strictly, which was mainly lied on the situation of cerebral anterior communicating
artery and posterior communicating artery and the cerebral collateral circulation.
In one patient with SAH and aneurysm of anterior communicating
artery, the mean serum N[a.sup.+] level decreased to 134 mmol/L three days after EVD insertion and maintained at the mean level of 135 mmol/L in the late period.
CT angiogram of the head and neck was done and revealed occlusion of his left internal carotid artery, poor opacification of the left ophthalmic artery, and the presence of good collateral flow from the left posterior cerebral artery and the anterior communicating
artery (Figures 1 and 2).
The left A1 segment was not visualized while the left A2 segment was supplied by a patent anterior communicating
Cerebral angiography demonstrated an aneurysm arising from the anterior communicating
The anterior cerebral arteries interconnect to the anterior communicating
artery whose patency allows interhemispheric potential shunts in case of obstructions or stenoses in the vascular network .
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

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.
