Adult Left Liver Transplantation With Mesocaval Shunt With Porto-Mesenteric Disconnection: Long-Term Outcome.

Summary: When adults receive a partial liver transplant, doctors sometimes create a special bypass (called a shunt) to lower the blood pressure in the new, smaller liver. This helps the liver survive and grow. However, a long-term study found a hidden catch. Years after the surgery, several patients with this bypass developed brain confusion caused by high ammonia levels in their blood. Fortunately, most were easily treated with standard medications, though one patient needed surgery to close the bypass. While the bypass helps the liver early on, doctors must watch out for this late side effect.
