I went in to complete a CTA and was injured as a result.  The nurse used a Lardner 20 or 22 mm needle which she stated was necessary to administer an iv.  During the CTA the radiology tech pushed too much iodine thru the iv resulting in an infiltration and my arm expanding like a ballon. I could feel my vein burst and extreme pain.  The radiology tech then added a heat compress and started pressing on my inflated arm which was burning and in sever pain.  I was seen by a doctor who said the iodine could damage tissue and could not be certain if the infiltration was saline or iodine.  I was told I should be ok but still have tingling and pain in my right arm.  I am going to file a formal complaint and have my vein and arm checked by a different facility.
