title: Morphological observation by intravascular ultrasound in superior vena cava syndrome after pacemaker implantation.
abstract: We report a case of superior vena cava (SVC) syndrome that was assessed by intravascular ultrasound (IVUS). A highly echogenic eccentric lesion was demonstrated by IVUS. The use of IVUS also confirmed in vivo that SVC syndrome following pacemaker insertion occurs as a result of intimal thickening of the venous wall.
