ABSTRACT
Angiographic diagnosis of lesions of the posterior fossa requires detailed knowledge of the normal anatomy of both arteries and veins of the brainstem and cerebellum. For this perfuse we measured normal distribution of the vertebrobasilar vessels from three base lines namely clival line, Twining line and foramen magnum line. In the measurement are also included some of the methods which were published in the past. This paper is based on the results of the measurements on 18 cases of normal vertebral angiogram among 77 cases of serial vertebral angiography performed at Catholic Medical center from October 1972 to August 1975. The result obtained were as follows: 1) Distance from the most posterior portion of the pericallosal artery to the clival line is 6.55+/-0.68 cm. 2) Distance from the most posterior portion of the arcuate portion of the lateral posterior choroidal artery to the clival line is 5.16+/-0.61 cm. 3) Distance from the posterior portion of the quadrigeminal portion of the medial posterior choroidal artery to the clival line is 4.87+/-0.67 cm. 4) Distance from the most posterior portion of the distal segment of the medial posterior choroidal artery to the clival line is 4.47+/-0.49 cm. 5) Distance from the bifurcation portion of the basilar artery to the clival line is 1.22+/-0.26 cm. 6) Distance from the forward convexity of the basilar artery to the clival line is 0.15+/-0.11 cm. 7) Distance from the choroidal point to the clival line is 2.99+/-0.51 cm. 8) Distance from the posterior medullary portion of the PICA to the clival line is 2.58+/-0.45 cm. 9) Distance from the tuberculum sellae to the Torcular Herophilli(Twining line) is 10.96+/-0.52 cm. 10) Distance between the tuberculum sellae to the point on the Twining line crossed by a perpendicular line drawn from the choroidal point is 6.61+/-0.40 cm. 11) Distance from the superior portion of the anterior culminate segment of the superior cerebellar artery to the Twining line is 3.28+/-0.48 cm. 12) Distance from the supratonsilar portion of the PICA to the Twining line is 0.97+/-0.42 cm. 13) Distance from the colliculocentral point to the clival line is 3.74+/-0.37 cm. 14) Distance from the crural portion of the anterior pontomesencephalic vein to the clival line is 1.65+/-0.33 cm. 15) Distance from the crural portion of the anterior pontomesencephalic vein to the colliculocentral point is 2.51+/-0.35 cm. 16) Distance from the copular point to the clival line is 3.99+/-0.51 cm. 17) Distance from the copular point to the line drawn from the anterior margin of the foramen magnum is 1.63+/-0.38 cm. 18) Distance from the highest point of the lateral posterior choroidal artery to the Twining line is 4.74+/-0.37 cm. 19) Distance from the highest point of the medial posterior choroidal artery to the Twining line is 4.35+/-0.34 cm. 20) Distance between two bisected points of the anterior culminate segment of the superior cerebellar artery by a line drawn parallel to the Twining line at 1cm from the top of the anterior culminate segment is 2.86+/-0.29 cm.
