1. To review the basic theory and technique for bariatric embolization. 2. To review the arterial supply of the stomach with a focus on the supply to the fundus.

     Bariatric embolization is a percutaneous interventional procedure in development, which seeks to help patients lose weight by targeting the ghrelin producing cells in the fundus of the stomach. Recent animal studies testing the procedure have been complicated by gastric ulceration, which makes knowledge of the arterial supply of the stomach and particularly the fundus important for developing a safe embolization technique for use in humans.      A literature review was performed to identify the vascular supply to the fundus. The left gastric artery and short gastric arteries are major suppliers to the fundus. Additional sources of fundal supply include the posterior gastric artery, left inferior phrenic artery, accessory left gastric artery, left gastroepipoloic and, less commonly, the left middle suprarenal artery.      Using CT angiography, graphical illustrations and digital subtracted angiography, we have demonstrated the arterial supply of the stomach. Digital subtracted angiography cine loops embedded in QR codes were used to demonstrate dynamic arterial filling. Selected illustrative cases were used to further demonstration arterial anatomy and pathology.
