Coloured X-ray of the chest of a 49 year old patient with Behcet's disease, showing a catheter inserting a coil into an aneurysm (ballooning) of a pulmonary artery in the lung. Endovascular coiling initiates a clotting reaction that eliminates the aneurysm. Behcet's disease is an inflammation of the blood vessels.
