Résumé
Superior vena cava (SVC) obstruction leading to SVC syndrome is an uncommon but potential complication of cardiac surgeries that involve dissection and anastomosis around the great vein. We present a case of iatrogenic SVC obstruction that was initially treated with transcatheter balloon angioplasty, which provided temporary relief, and ultimately resolved by stenting the affected segment. The index case underwent total anomalous pulmonary venous connection (TAPVC) repair and presented 3 months after surgery with features of SVC obstruction. Initially, transcatheter balloon angioplasty was performed, providing relief from the obstruction; however, the condition recurred within one month. Finally, the patient was treated with percutaneous stenting of superior vena cava, through femoral venous route, using 8 mm × 30 mm balloon-expandable bare metal stent (Formula 418, Cook Medical, Bloomington, IN). Remarkable relief of obstruction was established with decrease in mean gradient across SVC-right atrium junction to 2 mm Hg (from 12 mm Hg before balloon angioplasty and 18 mm Hg before stenting). Percutaneous treatment for iatrogenic SVC obstruction developing after cardiac surgery appears to be effective. Close monitoring is required in the postoperative period for early diagnosis and timely intervention.

BACKGROUND
BACKGROUND
Superior vena cava (SVC) obstruction leading to SVC syndrome is an uncommon but potential complication of cardiac surgeries that involve dissection and anastomosis around the great vein. We present a case of iatrogenic SVC obstruction that was initially treated with transcatheter balloon angioplasty, which provided temporary relief, and ultimately resolved by stenting the affected segment.
CASE PRESENTATION
METHODS
The index case underwent total anomalous pulmonary venous connection (TAPVC) repair and presented 3 months after surgery with features of SVC obstruction. Initially, transcatheter balloon angioplasty was performed, providing relief from the obstruction; however, the condition recurred within one month. Finally, the patient was treated with percutaneous stenting of superior vena cava, through femoral venous route, using 8 mm × 30 mm balloon-expandable bare metal stent (Formula 418, Cook Medical, Bloomington, IN). Remarkable relief of obstruction was established with decrease in mean gradient across SVC-right atrium junction to 2 mm Hg (from 12 mm Hg before balloon angioplasty and 18 mm Hg before stenting).
CONCLUSION
CONCLUSIONS
Percutaneous treatment for iatrogenic SVC obstruction developing after cardiac surgery appears to be effective. Close monitoring is required in the postoperative period for early diagnosis and timely intervention.
