It is defined as the loss of the histo- and cyto-architecture of vascular tissue structures and is at the basis of most congenital malformative pathologies that affect vascular structures, whether arterial, venous, or lymphatic. 


Definition of Angiodysplasia Angiodysplasia is a disease of the blood vessels in which structural abnormalities occur. These abnormalities can affect arteries, veins, or capillaries. In the gastrointestinal context, angiodysplasia is often located in the colon, small intestine, or stomach. Vascular malformations can vary in size and may cause bleeding, although they are not always symptomatic. 

Causes of Angiodysplasia The exact causes of angiodysplasia are not fully understood, but factors such as aging of blood vessels and high blood pressure are believed to contribute to the development of the condition. Some individuals may be more susceptible to developing angiodysplasia due to pre-existing vascular diseases or hereditary conditions such as hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome). 

Symptoms of Angiodysplasia Many people with angiodysplasia may be asymptomatic and only discover the condition during routine medical exams. However, when abnormal blood vessels rupture or bleed, symptoms such as: 

Bleeding: The primary symptom of angiodysplasia is bleeding, which can range from mild to severe depending on the severity of vascular malformations. Anemia: Due to chronic bleeding, some patients may develop anemia, which can cause fatigue, weakness, and pallor. Abdominal pain: In some cases, angiodysplasia can cause abdominal pain or discomfort. Changes in bowel frequency: Some individuals may notice changes in the frequency of bowel movements due to angiodysplasia in the colon. Dark stools or occult blood in stools: If bleeding is internal, blood may not be visible to the naked eye but can be detected through stool tests. 

Diagnosis of Angiodysplasia The diagnosis of angiodysplasia can be made through various tests and diagnostic procedures, including: 

Endoscopy: A procedure that allows the physician to directly visualize the inside of the gastrointestinal tract using an instrument called an endoscope. Colonoscopy: A specific variant of endoscopy used to examine the colon and rectum. Enteroscopy: An examination of the small intestine that can be helpful in detecting angiodysplasias in this part of the digestive system. Angiography: A procedure in which a contrast medium is injected into the blood vessels to obtain detailed images of vascular malformations. Blood tests: In cases of significant bleeding, blood tests may be performed to check hemoglobin and iron levels. 

Treatment of Angiodysplasia The treatment of angiodysplasia depends on the severity of symptoms and the location of vascular malformations. Treatment options may include: 

Electrocoagulation therapy: A process in which electrocautery is used to seal vascular malformations and stop bleeding. Laser coagulation therapy: A treatment in which a laser is used to coagulate blood and seal blood vessels. Cryotherapy: A treatment in which cold is used to freeze vascular malformations and stop bleeding. Embolization: A procedure in which a material is injected into the blood vessel to block blood flow to vascular malformations. Surgery: In severe or recurrent cases, surgery may be necessary to remove vascular malformations. 

Conclusion Angiodysplasia is a condition characterized by malformations of blood vessels, often located in the gastrointestinal tract. Bleeding is the primary symptom and can lead to anemia and other health problems. Timely diagnosis and appropriate treatment are essential to manage the condition and prevent complications. If you suspect you have angiodysplasia or have related symptoms, always consult a qualified medical professional for an accurate evaluation and an appropriate treatment plan.
