Gastric toxicity related to perfusion of the stomach via the left inferior phrenic artery during hepatic arterial infusion chemotherapy: report of two cases.

We present two cases of gastric toxicity related to hepatic arterial infusion chemotherapy (HAIC) for liver metastases. The gastric toxicity was caused by the inflow of infused drugs into the stomach via the left inferior phrenic artery arising from the celiac arterial trunk. The catheter hole was placed in the celiac arterial trunk with occlusion of the splenic and many gastric arteries. It must be kept in mind that perfusion of the stomach may occur through the left inferior phrenic artery in HAIC.
