angiodysplasia

Angiodysplasia of the caecum was found in one patient who also had a small adenoma.

Estrogens can be used to stop bleeding from angiodysplasia.

Superior mesenteric angiography may also show these lesions and angiodysplasia.

There is no pain associated with angiodysplasia.

In medicine (gastroenterology), angiodysplasia is a small vascular malformation of the gut.

Angiodysplasia of the colon is mostly related to the aging and degeneration of the blood vessels.

In Heyde's syndrome, aortic stenosis is associated with angiodysplasia of the colon.

Although angiodysplasia is probably quite common, the risk of bleeding is increased in disorders of coagulation.

Causes include: hemorrhoids, cancer, angiodysplasia, colitis, and aortoenteric fistula.

Other causes include: gastric or duodenal ulcers, Mallory-Weiss tears, cancer, and angiodysplasia.

A classic association is Heyde's syndrome (coincidence of aortic valve stenosis and bleeding from angiodysplasia).

If this shows angiodysplasia and the patient is known to have aortic stenosis, the combination is referred to as "Heyde's syndrome".

Angiodysplasia of the colon is very rarely related to other diseases of the blood vessels, including Osler-Weber-Rendu syndrome.

Diagnosis of angiodysplasia is often accomplished with endoscopy, either colonoscopy or esophagogastroduodenoscopy (EGD).

Rectal bleeding may also occur due to colorectal cancer, colitis including inflammatory bowel disease, diverticular disease, and angiodysplasia.

Ideally the initial investigation should be total colonoscopy as this will not only examine for malignant lesions but offers an opportunity to assess the mucosa for angiodysplasia.

Angiodysplasia of the colon is swollen, fragile blood vessels in the colon that occasionally result in blood loss from the gastrointestinal (GI) tract.

In angiodysplasia, a form of telangiectasia of the colon, shear stress is much higher than in average capillaries, and the risk of bleeding is increased concomitantly.

Warkentin et al. argue that apart from aortic valve stenosis, some other conditions that feature high shear stress might also increase the risk of bleeding from angiodysplasia.

A 2003 study found that of 73 angiodysplasia patients who had also undergone echocardiograms, the prevalence of aortic stenosis was 31% (as opposed to 14% in the control group).

In the absence of an obvious bleeding point, it is impossible to be certain that bleeding originates from the angiodysplasia until the rest of the gastrointestinal tract has been examined.

Its principal use is in providing haemostasis in gastrointestinal bleeding; angiodysplasia, GAVE, bleeding malignant tumours and bleeding peptic ulcers can all be treated.

It is known that such patients may have one of a variety of conditions such as arteriovenous malformations in the small intestine or colon (including angiodysplasia and telangiectasia), Meckel's diverticulum, Crohn's disease, and small bowel smooth muscle tumours.

Diverticulosis, Angiodysplasia, Infectious Colitis, Ischemic Colitis, Inflammatory Bowel Disease, Neoplasms, Radiation Telangiectasia and Proctitis, and NSAID Enteropathy and Colopathy are the causes of LGIB in adults.
