A very small skin incision is made at the site. Any procedure that places a catheter inside a blood vessel carries certain risks. The greatest difference in performing TIPS in children is their tremendous variability in size, physiology, and medical diseases. During a TIPS procedure, interventional radiologists use image guidance to make a tunnel through the liver to connect the portal vein (the vein that carries blood from the digestive organs to the liver) to one of the hepatic veins (three veins that carry blood away from the liver back to the heart). A stent is then placed under fluoroscopy extending from the portal vein into the hepatic vein. Move out of the vicinity of the MRI suite before verifying a valve setting. Once the stent is in the correct position, the balloon is inflated, expanding the stent into place. Some exams may use different transducers (with different capabilities) during a single exam.
