The CAT scan showed accumulation of the fluid and the mass almost achieving 80% of the previous size.  Therefore, I called the patient home and she came to the emergency department where the service was provided.  At that time, I proceeded to work on the pigtail catheter after obtaining an informed consent and preparing and draping the area in the usual fashion.  Unfortunately, the catheter was open.  I did not have a drainage system at that time.  So, I withdrew directly with a syringe 700 mL of clear fluid.  The system was connected to the draining bag, and the patient was instructed to keep a log and how to use equipment.  She was given an appointment to see me in the office next Monday, which is three days from now.
