Angiography > Exams & Procedures > Plasmapheresis
This procedure is performed to assist patients who require their blood to be cleansed intermittently. A double lumen (two channel) catheter is placed into a blood vessel (venous) near the neck. Local anaesthetic is given to numb the area and the catheter is placed with ultrasound guidance.
There is no special preparation for this test. However, if you are on blood thinners, aspirin, coumadin, tyclid, Plavix or Aggrenox, please stop taking this medication one week before, but only with your doctor's approval. A blood test may be taken when you are in the hospital.
