Dieulafoys aspirators theory, also known as the Dieulafoy's lesion theory, is a medical hypothesis proposed by French surgeon Paul Georges Dieulafoy in the late 19th century. This theory suggests that gastrointestinal bleeding can be caused by abnormal vascular malformations known as Dieulafoy's lesions. These lesions are characterized by the presence of a large, tortuous artery located just beneath the mucosal lining of the stomach or intestines. Alternative terms for the Dieulafoy's aspirators theory might include the Dieulafoy's lesion theory or the abnormal vascular malformation theory. Understanding the various synonyms for this concept is crucial for medical professionals to accurately communicate and diagnose gastrointestinal bleeding associated with Dieulafoy's lesions.
