This is an outpatient procedure. You will arrive at the hospital about one hour before the schedule time. An IV will be inserted for gentle hydration and any necessary "calming" medication. Although the arteriogram often takes less than an hour, it is necessary to stay at least three to four hours after the exam for monitoring after the calming medications and to observe the puncture site. The angiogram is done in the x-ray area, and once you are transported, you will be asked to lay on an x-ray table. Be sure you urinate prior to the test as the test may take sixty (60) minutes. In addition, you will be required to lie flat for four (4) hours after the test is completed. During the test, you will be given a sedative in the IV solution which should make you comfortable. Lidocaine is gently injected into the skin of your upper leg area or arm and a neddle is placed into the artery. This is followed by a very small tube through the needle which is advanced under x-ray guidance to the area of interest. You will be asked to hold very still, and contrast is injected. Sometimes, you may get a warm sensation with the injection, but it is not terribly uncomfortable | |||
