The treatment of aneurysm of the internal carotid artery within the skull has received the recent attention of Dandy1 and of Walsh and Love.2 Dandy recommends a procedure of "trapping the aneurysm" between two ligatures, one placed on the artery within the skull after direct inspection of the aneurysm and the other on the artery in the neck. He has reported three cases3 in which treatment by this approach was successful, the aneurysm in each instance being small, pea sized and readily mobilized. Larger aneurysms are difficult to handle in this way, and for these there remains, in general, ligation of the artery in the neck; this procedure is discussed at length in the papers of Walsh and Love.2 Although successful results have been obtained, this operation does not always arrest the growth of the lesion, while it does carry with it the risk of ensuing
