A portacath is projected over the left lung, with the tip located in the superior vena cava.
On injection of contrast, the catheter lumen opacifies, but does not ever the SVC. Instead, contrast pools around the subcutaneous tract and exits into the subcutaneous chest tissue.
A portacath is an implantable vascular access device used for medium to long term intravenous access, e.g. in patients requiring chemotherapy.
Although they can be left in situ for years, complications can include infection, extravasation and migration of the portacath.
In this patient, the port was removed and a replacement device inserted.
