Abstract
A series of 27 patients under went venography through the ipsilateral cubital vein in pacemaker implantation at pacemaker generator exchange. Of these 27, revealed complete obliteration of the subclavian vein, including 1 in which venous obliteration extended to the left vena innominate. One of the obliteration of the subclavian vein required additional insertion of a transvenous pole, but ipsilateral puncture was thought possible as a result of venography, so the pole was inserted by puncturing a central portion of the ipsilateral subclavian vein.
In cases of venous obliteration involving the left vena innominate, ipsilateral addition of a pole is not possible. It is thought useful to preced operation with ipsilateral venography.
