...S. Çavdar; H. Dalçik; A. Yaıln The posterior inferior cerebellar artery (PICA) is normally a branch of the vertebral artery. In this rare case, the unilateral left vertebral artery continued its course as the left PICA, and an extremely small caliber left vertebral artery joined the right vertebral...

...C. Taitz; B. Arensburg Thirty-six vertebral arteries were examined for the presence of tortuosity in their trajectory through the neck. Of these, 18 vessels (14 bilateral) showed various degrees of tortuosity of their proximal segment. Four arteries had marked kinking of the tortuous vessel...

...Safiye Çavdar; Erdal Arisan The aim of this study is to demonstrate a case of a cadaver in which both left and right vertebral arteries had an abnormal origin. On the left, the artery arose directly from the arch of the aorta. On the right, a double-originating vertebral artery was seen...

...Huai-jing Wang; J.R. Casley-Smith Carbon particles injected into the cortex of the cerebellum of the rat were found in the Virchow-Robin spaces of the adjacent capillaries, and in the adventitia of the cerebellar artery, basilar artery and vertebral artery -both inside and outside the skull...

... is presented incriminating the tortuosity of the vertebral artery as well as congenital factors in the etiology of the erosion of the FT. Attention is drawn to the possible correlation between angulation of the transverse process of the axis and erosion of the FT. 2 05 1988 20 05 1988 15 7 2008...

...Hilel Nathan; Michael R. Seidel The findings in a cadaver demonstrated: (a) an aberrant retroesophageal right subclavian artery (RRSA); (b) a thoracic duct (Th.d.) terminating at the junction of the right internal jugular and subclavian veins (‘venous angle’), and (c) a left vertebral artery (LVA...
