The BCV compression with jugular reflux to the intracranium has been accidentally found in patients receiving dynamic brain scintigraphy or brain MR imaging [19 ,20 ,29 ,33 ], with the frequency of this phenomenon estimated at about 0·2% to 0·4% [19 ], and the association between BCV compression to TGA has been previously proposed by our team [19 ].
