The available methods of treatment are ligation of the right common
carotid and third part of the right subclavian (Wardrop's operation), of
which a number of successful cases have been recorded. Those most
suitable for ligation are cases in which the aneurysm is circumscribed
and globular (Sheen). If ligation is found to be impracticable, the
Moore-Corradi method or Macewen's needling may be tried.
