Venous pseudoaneurysm in a dialysis patient

We present a case of embolization for post-angioplasty pseudoaneurysm of the internal mammary vein. A 62-year-old male presented to the emergency department with right upper extremity edema. One month prior, he underwent angioplasty of right cephalic, subclavian, and innominate veins for similar symptoms but felt they had worsened. Computed tomography with intravenous contrast revealed pseudoaneurysm of the right internal mammary vein, and the patient was taken emergently to the operating room where embolization was successfully performed. Central venous pseudoaneurysm is a rare complication of angioplasty and the unique considerations of the anatomic region necessitate discussion of the optimal treatment modality.
