Abstract：Objective To provide anatomical basis for selecting the types and placing parts of vascular stent. Methods Twenty head specimens were selected and the A1 segment of anterior cerebral artery and its perforators were measured by the pterion approach. One hundred digital subtraction angiography(DSA) images with no diseases of whole brain were selected, the course of the A1 segment of anterior cerebral artery and the opening parts of its perforators were observed. Results The length and external diameter of the microanatomy were (13.55±1.43)mm and (2.43±0.37)mm, respectively. The length and diameter of the DSA angiography of the A1 segment of anterior cerebral artery were (13.42±1.57)mm and (2.28±0.40)mm respectively. There were significant differences in the diameter between the microanatomy and DSA angiography (P<0.05). The perforators of the A1 segment of anterior cerebral artery originated from its posterior and superior wall, the branches of the proximal, middle and distal segment were 2.55±0.39, 0.52±0.46, and 1.12±0.10, respectively. There were significant differences in the perforators among the proximal, middle and distal segment (all P values<0.05). The male A1 segment of anterior cerebral artery was longer than that of the female, there were significant differences in length and diameter respectively (all P values<0.05). Conclusions Microanatomy and digital subtraction angiography comparative observation of the A1 segment of anterior cerebral artery has an important clinical significance for selecting the types and placing parts of vascular stent, avoiding obstruction the opening parts of perforators, preventing postoperative ischemia of the supply area of perforators.
