A left vertebral artery angiogram demonstrated that the branches of the vertebral artery extending into the rear of the neck had expanded and proliferated markedly, and extravasation of contrast material was detected in the peripheral branches (fig. 3). We embolized the artery by injecting an emulsion of n-butyl-2-cyanoacrylate and iodized oil at a ratio of 1:4 (Histoacryl/Lipiodol) (fig. 3).
