Pseudoaneurysm of gastroduodenal artery following radical gastrectomy for gastric carcinoma patients

摘要

We report a rare case of postoperative pseudoaneurysm of the gastroduodenal artery following radical gastrectomy. Surgical trauma to the gastroduodenal artery during regional lymphadenectomy was considered as the cause of the postoperative pseudoaneurysm. The pseudoaneurysm was successfully managed by ligating the bleeding vessel. We should consider the possibility of pseudoaneurysm formation in a patient with gastrointestinal bleeding in the postoperative period following radical gastrectomy with regional lymph node and perivascular lymphatic dissection.
