Vein surgery. Coloured angiogram (X-ray) of surgery to lower the blood pressure in the portal vein of a 60 year old patient. A catheter (white line running down from top centre) has been used to form a channel (shunt) between the portal vein, which moves blood from the digestive system to the liver, and the hepatic vein, which carries blood away from the liver. A stent (curved wire mesh tube, red) is holding this TIPSS (transjugular intrahepatic portosystemic shunt) open. The high blood pressure has been causing oesophageal bleeding.
