 After the procedure and before starting the HAI based treatment, a technetium 99m-labeled macroaggregated albumin scan is performed to again confirm adequate hepatic perfusion and no misperfusion outside of the liver.The complications of HAI therapy can be divided into those related to the surgical placement of the pump, technical catheter-related complications, and those related to the chemotherapeutic agents used.Relating to the surgical HAI pump placement, early postoperative complications consist of arterial injury leading to hepatic artery thrombosis, inadequate perfusion of the entire liver due to the inability to identify an accessory hepatic artery, extrahepatic perfusion to the stomach or duodenum, or hematoma formation in the subcutaneous pump pocket.
