Overview
Natural History
- Small bowel angiodysplasia (SBA) contributes to 50% of obscure GI bleeding cases.[1]
- SBA tends to re-bleed more than angiodysplasia of the colon and stomach.
- In a retrospective study, re-bleeding occurred after about 11 months of diagnosis in 80% of patients, and 3.5% died as a direct result of bleeding.[1]
- Multiple lesions and valvular heart diseases have been found to increase the risk of re-bleeding.
- Apart from recurrence of bleeding, some other concerns in the natural history of angiodysplasia are transfusion requirements, hospital readmissions, and requirement endoscopic, pharmacological, or surgical therapy.
- In asymptomatic people, the course of angiodysplasia is benign, and the bleeding risk is low. Consequently, treatment is not required for incidentally found lesions.[2]
Complications
- Iron-deficiency anemia
- Death from excessive blood loss
- Side effects from treatment
- Severe loss of blood from the GI tract
Prognosis
- The prognosis of angiodysplasia in asymptomatic patients is good as the bleeding risk is low.
- In 90% of cases, angiodysplasias stop bleeding spontaneously which might be the result of the venous nature of angiodysplasias.[3]
- Advanced age, severe bleeding and hemodynamic instability, and the presence of co-morbid medical conditions like coronary artery disease, type 2 diabetes mellitus may contribute to mortality in these cases.
