A 62-year-old man had stage 4 malignant mesothelioma complicated by SVC syndrome. CT shows complete SVC obstruction (arrow, a ). Venography revealed a low SVC obstruction (arrow, b ). A 16-mm wallstent (Boston Scientific) was placed, but the stent migrated caudally with the bottom end in the low right atrium (black arrow, c ). An 18-mm wallstent was placed within the initial stent extending into the intrahepatic IVC stabilizing the first stent and preventing its migration into the right ventricle (arrow, d ).
