A 50-year-old woman had a prior history of thymic carcinoid (initial PET-CT, a ; arrow—PET-avid tumor) treated with 60 Gy of RT. Two years after treatment, she developed facial and RUE edema with bothersome dilation of subcutaneous collateral vessels. Contrast-enhanced CT ( b ), which showed incidental duplication of the SVC (arrow), demonstrated no evidence of residual disease but did show severe stenosis of the right-side SVC (circle) thought to be due to prior radiation therapy. The stenosis was confirmed by catheter venography (arrow, c ). A 16-mm-diameter Abre (Medtronic) stent was placed and postdilated to 10 mm with brisk flow through the previously seen stenosis ( d ). Symptoms improved by postprocedure day 1. Three-month follow-up CT showed stent patency ( e ).
