[Prevention and management of pseudoaneurysm after radical gastrectomy for gastric cancer].

With the promotion of standard radical resection of gastric cancer, the incidence of postoperative pseudoaneurysm is significantly increasing. Both the patient's own factors and iatrogenic factors are accoutable. Surgeons should clarify the causes of pseudoaneurysm, pay attention to the clinical symptoms and signs, and treat the patients appropriately. In order to avoid the occurrence of postoperative pseudoaneurysm, surgeons should carefully evaluate the preoperative conditions, perform precision operation and reduce the morbidity of postoperative infection and fistula.
