目的 :探讨脚池的显微解剖特点及其临床意义。方法 :在手术显微镜下 ,观测 15例尸颅脚池的构成及其结构特点。结果 :脚池位于大脑脚与颞叶之间 ,居于环池的前面及上面 ,仅见于半数标本。脚池的底壁呈网膜样 ,多数自钩向内上方伸展 ,前后长度为 6 .0～ 12 .0mm。该壁越向后越窄 ,在部分标本明确分隔脉络膜前动脉和后交通动脉。脚池的内侧壁为大脑脚 ,顶壁为视交叉、视束及前穿质 ,外侧壁为颞叶内侧面 ,向前开放于颈动脉池。结论 :脚池不是脚间池向后外侧方的延伸 ,二者相互独立 ,池内也并不含有内侧脉络膜后动脉。由于脚池底膜变异大 ,难以成为可靠的标志。手术中达到后交通动脉池时 ,若在外上面见一层网膜样结构 ,不要轻易打开 ,因为此膜上面几乎总是脉络膜前动脉及其分支
Objective: To investigate the microscopic anatomical characteristics of foot pool and its clinical significance. Methods: Under the operation microscope, the structure and structure of 15 cadaver feet were observed. Results: The foot pool was located between the brain and the temporal lobe, and was located in front of and above the ring pool, only seen in half of specimens. The bottom wall of the foot pool was omentum-like, the majority of stretching from the upper inward, before and after the length of 6 .0 ~ 12 .0 mm. The narrower and narrower the wall, the anterior part of the anterior and the posterior communicating artery were clearly separated in some of the specimens. The inner wall of the foot pool is the cerebral peduncle, the top wall is the optic chiasm, the visual tract and the anterior perforating material, the lateral wall is the medial side of the temporal lobe, and the anterior wall is open to the carotid artery pool. Conclusion: The foot pool is not an extension of the foot pool to the posterolateral side, and the two are independent of each other. The inside of the pool also does not contain the internal choroidal artery. Due to the large variation of the foot basement membrane, it is difficult to be a reliable indicator. After surgery to reach the posterior communicating artery pool, if you see a layer of omentum-like structure outside, do not easily open, because this film is almost always the anterior pre-choroidal artery and its branches
