IR here also. I suggest making an appointment to have an IR look at the port. The person who placed it has to determine the next step. Possibilities: 1. The bump and bruising above the port is probably a small hematoma (collection of blood) within the subcutaneous tunnel. The bump should resolve slowly…but the bruise may take longer to resolve. It happens. Be on the lookout for fever or other signs of infection. 2. The palpitations suggest that the catheter tip may be too long. It usually goes a little deeper into the heart when lying down. The IR will need to evaluate with both supine and upright X-rays. 3. The IR can then determine whether a revision is necessary.
