[X-ray anatomy of the superior cerebellar artery (1)].

The anatomic and angiographic variants of the superior cerebellar artery were studied in 50 macro-preparations of the cerebellum and in 100 normal angiogrammes. The authors distinguish five angiographic variants of the superior cerebellar artery, and emphasize the necessity of their differentiation for proper identification of its branches in interpreting the angiogrammes. Quantitative characteristics is given to the segments of the superior cerebellar artery and their angles, which permits a more precise assessment of the displacement of the superior cerebellar artery.
