Renal Vein Duplex

To rule out renal vein thrombosis.


  • Patient with a known renal carcinoma with concern for extension into the renal vein.
  • Inferior vena cava thrombus.
  • Right atrial thrombus/mass.


NPO 4 hours prior to the exam. If the patient is diabetic and unable to abide by this preparation, we will work with the patient. Please allow the patient to eat. Suggest that he/she eat as light a meal as possible and foods which are non-gas producing. If the patient must take diabetic medications just prior to eating, please ask them to bring the diabetic medications to the appointment. Preferably schedule the patient in the AM.
