Topographic measurement of the superior vermian vein by lateral vertebral phlebography.
The position of the superior vermian vein (SVV) has been defined by means of an easily constructed triangular system with two fixed points and by determination of quotients of measured lengths or angles. 100 normal lateral vertebral phlebograms with well outlined SVV and accurate projection were thoroughly measured and calculated. Since SVV was found to occupy a constant position in the reference system used, certain quotients and angles might be suitable for diagnosis.
