Objective: To explore the origin, branch, course and variation of the arteries on the base of the brain and provide the anatomical basis for interventional neuroradiologic procedures. Methods: 60 cases chinese adult cadaveric brain were well prepared for the sake of surveying the origin, branch, course and variation of circle of willis and measuring its length, external diameter. Results: Regardless of the fact that variations of arteria basilaris were very common, laws can be also followed during the interventional approach: 81.5% ACAs originated from the anterior wall of ICAs, 67.2% ACoAs communicated with the lateral wall of ACAs, 75.5% PCoAs came from the posterior-external wall of ICAs and 88.3% PCAs came from external wall of BAs. Conclusions: The consulting length and diameter data of circle of Willis provided for chinese are offered in this study. Those are useful for catheterization and beneficial to prefabricate special catheters and guding wires.
