The current clinical diagnosis and management of small bowel bleeding caused by a primary aortic fistula: A literature review

Abstract

Background: Primary aortic intestinal fistula is caused by erosion, rupture, and perforation of the adjacent digestive tract of the arterial wall, and the mortality rate is extremely high, the preoperative diagnosis rate is only 0%~36%, and the autopsy detection rate is only 0.04%~0.007%. Because there are no typical clinical symptoms that have not been detected, it is necessary to expand the sample size and further explore its etiology, pathophysiology, and pathogenesis to improve the diagnosis rate and the relevant diagnosis and treatment techniques. Methods: This study focuses on understanding primary aortic fistula-induced small bowel hemorrhage. We gathered electronic search data from Scopus, Medline, Google Scholar, PubMed, Springer, and CNKI. Recommendations were extracted from the identified articles. Conclusion: To identify small intestinal hemorrhages as quickly as feasible and provide prompt and effective care, professionals should devote more attention to diagnosing and treating small intestinal bleeding and increase public awareness of the condition.
