The appendiceal artery is a branch of the ileocecal artery, so it originates from the ileocecal artery, starts from the lower part of the ileocecal artery down around the cecum, passes through the end of the ileum into the appendiceal mesentery, goes around the appendix to the tip of the appendix, and finally the artery flows into the portal vein together with the appendiceal vein. The appendiceal artery is an important artery for the body and obstruction of its flow can sometimes lead to appendicitis or, in severe cases, necrosis of the appendix. When the appendiceal artery is diseased, it is necessary to go to the hospital for examination and treatment, and if necessary, to choose appendectomy to avoid other diseases.
