我们在50侧(成人6,儿童44)头颅标本上观察了颈内动脉海绵窦段的分支和吻合,结果为:1.颈内动脉海绵窦段由近及远分为第一弯曲、第二弯曲及由两个弯曲分成的后升部、水平部和前升部。2.颈内动脉此段分支有脑膜垂体干和海绵窦下动脉,某些例还有被囊动脉。脑膜垂体干常发出小脑幕动脉、脑膜背侧动脉和垂体下动脉。根据颈内动脉此段一级分支的数目可将其分为一支型、二支型、三支型和四支型。3.介绍了该动脉此段各分支的起源、直径、经过和分布。4.描述了该动脉此段分支的吻合,并讨论其临床意义。5.对显微外科手术有实用意义的 Par-kinson 氏三角也作了测量。
We observed on the 50 side (adult 6, children 44) cranial specimens of the carotid artery cavernous sinus branch and anastomosis, the results are: 1. Carotid cavernous sinus segment from near and far into the first bend, the second Bending and bends divided by two bends, horizontal and forward. 2. This section of the carotid artery branch of the meningioma and cavernous sinus artery, in some cases also capsule capsule. Meningeal pituitary stem often issued cerebellar artery, dural artery and pituitary artery. According to the internal carotid artery in this section a number of branches can be divided into a type, two branches, three branches and four branches. 3. Describe the origin, diameter, passage and distribution of the branches in this section of the artery. 4. Describe the anastomosis of this segment of the artery and discuss its clinical significance. 5. Par-kinson’s trigonometry, which has practical implications for microsurgery, was also measured.
