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.

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 artery.

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 [4].
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 artery--AcomA).
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).
