The artery forms then a second upward and forward curve and reaches the foramen magnum, where it penetrates the dura forming the last segment (V4). It is conceivable that these curves protect the VA, allowing it to accommodate more easily movements in the atlanto-occipital region (Fig. 6.1).无表情 发表于 2025-3-29 07:46:04

An accurate description of this pathology as a definite congenital malformation was proposed by McCormick (1966). The same author made a classification, which, with a few modifications (Challa et al. 1995; Yasargil 1987, 1999; Chaloupka and Huddle 1998; Valavanis et al. 2004), is still valid today.暂时过来 发表于 2025-3-29 22:56:43
