Duodenal ulceration into the cystic artery.

摘要

We report two cases of massive gastrointestinal bleeding due to anterior duodenal ulceration into the cystic artery, with gallbladder infarction as a complication. These cases indicate the potential dangers of laser therapy or embolization in bleeding anterior duodenal ulcers penetrating the cystic artery, as such therapy will arrest blood flow through the cystic artery and may precipitate gallbladder infarction.
