Arteriography

Even if more modern techniques are available (angiography, ultrasound, CT and nuclear magnetic resonance), arteriography is useful to see a narrowing or obstruction of blood through the quality of its images. It is mainly performed for coronary arteries, brain, gastrointestinal, renal, and those of lower limbs. It requires a short hospital stay.

Its principle is simple: to make it opaque to X-rays a set pressure by direct injection into the artery of origin of this set of a dye.
This is made possible by the introduction in a peripheral artery with a catheter that is made to walk up to the desired location.
The photographs taken during and after injection can see how perfect this artery, and all those who came.

The first requirement to comply is to prevent the doctor if you have any allergies to iodine. If applicable, where there is doubt whether he will be required to begin treatment a few days earlier.
Also, if you are taking anticoagulant therapy, it is necessary to stop two days before, in the case of tablets and half a day before the examination in case of injections.

Finally, a blood test be performed a few days ago and you will need to be fasting since the previous evening.

The review usually happens under local anesthesia and can last up to an hour. An unpleasant sensation and fleeting warm current spreading throughout the body is often felt during the injection of iodine. Finally, a compression bandage is installed at the puncture site to prevent any risk of hematoma.
