在50具身体[人]脑中，确定了对前交通区域动脉瘤手术重要的微血管关系。在确定大脑前动脉瘤的颈时，Heubner返动脉常暴露在A-1段之前，因为它通常在A-1段之前走行。78%起源于大脑前动脉(ACA)的A-2段，最常终止于前孔区，侧裂位于前孔区外侧。前交通动脉(ACOA)常发出穿支动脉，其终止点位于视交叉上表面和下丘脑前交叉之上。这一发现与之前报道的交通动脉无穿支形成对比。A-1段的近半段比远端半段有更丰富的穿支动脉来源。A-1支最常终止于前穿孔物质、视交叉和视束区域。前交通动脉大小随左、右A-1段直径差增大而增大。常见的变异有双或三前交通动脉S、AAA-2节段和A-1节段重复，本文回顾了闭塞返动脉、前交通动脉穿支和A-1内、外侧段的临床后果。
The microvascular relationships important to surgery of aneurysms in the anterior communicating region were defined in 50 cadaver [human] brains. The recurrent artery of Heubner was frequently exposed before the A-1 segment in defining the neck in anterior cerebral aneurysms because it commonly courses anterior to A-1. It arose from the A-2 segment of the anterior cerebral (ACA) in 78% and most commonly terminated in the area of the anterior preforated substance, and lateral to it in the Sylvian fissure. The anterior communicating artery (ACoA) frequently gave rise to perforating arteries which terminated in the superior surface of the optic chiasm and above the chiasm in the anterior hypothalamus. This finding contrasts with previous reports that no perforating branches arise from the communicating artery. The proximal half of the A-1 segment was a richer source of perforating arteries than the distal half. The A-1 branches most commonly terminated in the anterior perforated substance, the optic chiasm and the region of the optic tract. The ACoA increased in size as the difference in the diameter between the right and left A-1 segments increased. Frequent variants such as double or triple ACoA''s, triple A-2 segments and duplication of the A-1 segments were encountered. The clinical consequences of occlusion of the recurrent artery and of the perforators from the ACoA and medial and lateral segment of A-1 are reviewed.
