An Unusual Case of Gastric Outlet Obstruction After Embolization of Gastroduodenal Artery Pseudoaneurysm

An Unusual Cause of Gastric Outlet Obstruction

“…The presentation of GOO is nonspecific, and a diagnosis of malignancy always needs to be ruled out. 1 Patients usually present with emesis, nausea, epigastric pain and fullness, intolerance to solid food, early satiety, and poor appetite. Often, common etiologies of GOO include pyloric, duodenal, or pancreatic head malignancy.…”

“…To evaluate the cause of GOO, a patient should undergo abdominal radiography, contrasted gastro-intestinal studies and esophagogastroduodenoscopy. 1 Visceral pseudoaneurysms are commonly found in those aged 50-58 years and are known to be found in the splenic artery (46%), renal artery (22%). and hepatic artery (16.2%).…”

“…and hepatic artery (16.2%). 1,2 Common presentations of visceral pseudoaneurysms include hypotension owing to acute hemorrhage or incidental findings due to the increased use of CT scans. The most dangerous complication of pseudoaneurysm is rupture leading to hemorrhage, which has a mortality rate of 17%, and happens when the pseudoaneurysm enlarges owing to intracystic pressure.…”
