A UTMB surgical team placed a shunt in Kaden Ochoa, 4, to bypass a portal vein obstruction and restore full blood flow to his liver — a first in the state of Texas. “The surgery went very well,” said Dr. Ravi Radhakrishnan, chief of UTMB pediatric surgery. “We were able to bypass the obstruction and restore all the blood flow back to Kaden’s liver.”
