摘　　要：目的　为高血压性脑出血好发生于壳核的原因提供形态学依据。②方法　采用镜下解剖和脑血管铸形方法 ,对 5 0侧脑标本、5例脑血管铸形标本壳核动脉的形态学特点进行了观察。③结果　 5 0侧大脑半球共观察到 392支壳核动脉 ,平均每侧 (7.8± 2 .6 )支。 392支壳核动脉中 80 .6 %来源于大脑中动脉 ,17.9%来源于大脑前动脉 ,1.5 %来源于脉络膜前动脉。壳核动脉行程迂曲 ,在穿入壳核时尚形成弓状、环状弯曲 ,其直接形成直径 <0 .10mm分支情况亦明显高于基底核区其他结构的供血动脉 (χ2 =6 1.191,P <0 .0 1) ,且 76 .0 %的壳核动脉起于大脑中动脉分叉处 2 .0 0mm范围内。④结论　壳核动脉无论从起源、行程情况还是从其分支的发出形式上来讲 ,都与脑出血的发生具有密切关系。Objective\ To supply the morphological basis for explaining the fact that hypertensive cerebral hemorrhage more often seen in putamen. \ Methods\ The technique of micro anatomical and cerebral vascular cast were used for investigation of morphological features of putamen artery in 50 cerebral specimens and 5 cerebral vascular casts.\ Results\ 392 putamen arteries were discovered in 50 cerebral hemispheres , being 7.8±2.6 arteries per hemisphere. Based on their origins, these arteries were divided into three groups: 80.6% of the studied arteries arose from the middle cerebral artery (MCA). 17.9% originated from the anterior cerebral artery (ACA). 1.5% derived from the anterior choroidal artery (AChA). The putaminal arteries not only wound through their way, but also formed a bow shape or circularity when they entered the nuclei. The frequency of giving off direct branches, less than 0.10mm in diameter, was higher in the putaminal arteries than that in the other arteries of striatum and internal capsule ( χ 2=61.191, P <0.01). \ Conclusion\ Putaminal artery is closely related to the cerebral hemorrhage in terms of its origin, route and branches.
