Abstract

Angiodysplasia or vascular ectasia of the intestine is a new pathological entity which was initially revealed by arteriography. More recently it has been found by coloscopy and is considered to be responsible for many cases of intestinal bleeding, especially in older patients The present study is based on eight patients including 2 cases of microscopic bleeding, 4 of massive hemorrhage, and 2 asymptomatic cases. There is a clear difference between intestinal angiodysplasia and other forms of vascular malformations, even though its pathogenesis is still in question. Whereas in older patients it is acquired, typically in the caecum. It can also exist congenitally in younger patients and in other locations. However, identical lesions may be observed at all levels of the digestive tract in association with certain diseases, most often vascular atheroma, but also diverse intestinal diseases (diverticulitis, colitis, polyps, cancer) and even iatrogenic diseases. Even though these malformations are frequent, the lesions often go unrecognized because special histological technics are required to reveal the arteriovenous fistulas. The major circumstance leading to this diagnosis is anemia due either to occult intestinal bleeding or mass...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
