MS-1337

A 54-year-old male presents to the emergency department with frank haematemesis. He is urgently resuscitated and undergoes an urgent oesophagogastroduodenoscopy (OGD), which reveals an active bleed in the distal part of the lesser curvature of the stomach. The bleed is successfully controlled with endoclips and adrenaline. The patient has a history of gastric ulcers. What is the most probable artery responsible for the bleeding?
