✓ Two cases are presented in which clip occlusion of a third distal anterior cerebral artery segment occurred during treatment of anterior communicating artery aneurysms. Case histories, angiograms, operative descriptions, and postmortem findings are presented. The incidence of this anomalous vessel is reviewed. Preoperative and intraoperative vigilance in determining the presence of this anomaly prior to clip placement is emphasized.

Distal Anterior Cerebral Artery

✓ The microsurgical anatomy of the distal anterior cerebral artery (ACA) has been defined in 50 cerebral hemispheres. The distal ACA, the portion beginning at the anterior communicating artery (ACoA), was divided into four segments (A2 through A5) according to Fischer. The distal ACA gave origin to central and cerebral branches. The central branches passed to the optic chiasm, suprachiasmatic area, and anterior forebrain below the corpus callosum. The cerebral branches were divided into cortical, subcortical, and callosal branches. The most frequent site of origin of the cortical branches was as follows: orbitofrontal and frontopolar arteries, A2; the anterior and middle internal frontal and callosomarginal arteries, A3; the paracentral artery, A4; and the superior and inferior parietal arteries, A5. The posterior internal frontal artery arose with approximately equal frequency from A3 and A4 and the callosomarginal artery. All the cortical branches arose more frequently from the pericallosal than the callosomarginal artery. Of the major cortical branches, the internal frontal and paracentral arteries arose most frequently from the callosomarginal artery. The distal ACA of one hemisphere sent branches to the contralateral hemisphere in 64% of brains. The anterior portions of the hemisphere between the 5-cm and 15-cm points on the circumferential line showed the most promise of revealing a recipient artery of sufficient size for an extracranial-intracranial artery anastomosis. The distal ACA was the principal artery supplying the corpus callosum. The recurrent artery, which arose from the A2 segment in 78% of hemispheres, sent branches into the subcortical area around the anterior limb of the internal capsule.

✓ Between June, 1961, and September, 1975, the authors operated on 60 patients with aneurysms of the anterior cerebral artery distal to the anterior communicating artery (ACoA) by a direct intracranial approach. It is of utmost importance in the treatment of aneurysms to have control of the parent artery of the aneurysm. This makes it easier and safer to approach the aneurysm neck and to handle possible premature aneurysm rupture. The aneurysms were classified into two types, ascending and horizontal. Aneurysms arising from the origin of the ACoA and including the entire portion of the knee of the corpus callosum were designated as aneurysms of the ascending portion, whereas aneurysms beyond the genu were designated as aneurysms of the horizontal portion. For aneurysms of the ascending portion, bifrontal craniotomy was considered the safest approach. For aneurysms of the horizontal portion, a small parasagittal craniotomy was determined to be sufficient.
