We report a case of superior vena cava (SVC) syndrome that was assesse
d by intravascular ultrasound (IVUS). A highly echogenic eccentric les
ion was demonstrated by IVUS. The use of IVUS also confirmed in vivo t
hat SVC syndrome following pacemaker insertion occurs as a result of i
ntimal thickening of the venous wall. (C) 1996 Wiley-Liss, Inc.
