Background. Angiodysplasia is the most common vascular lesion of the gastrointestinal tract, and this condition may be asymptomatic, or it may cause gastrointestinal (GI) bleeding. The vessel walls are thin, with little or no smooth muscle, and the vessels are ectatic and thin (see image below).Angiodysplasia identified on cecum wall during colonoscopy. Phillips first described a vascular abnormality that caused bleeding from the large bowel in a letter to the London Medical Gazette in 1839.n the case of the colon, wall tension refers to intramural tension, the pressure difference is that between the bowel lumen and the peritoneal cavity, and cylinder radius is the radius of the right colon. Wall tension is highest in bowel segments with the greatest diameter, such as the right colon.
Down syndrome (sometimes spelled âDownâs syndromeâ) is a genetic abnormality. It is the most common single cause of birth defects in the United States (NIH, 2012).
