Angiodysplasia of the Colon

Updated : January 5, 2024





Background

  • Angiodysplasia of the colon, also known as colonic angiodysplasia or vascular ectasia, is a condition characterized by abnormal, enlarged blood vessels in the colon. These blood veins can bleed easily and are fragile, which can result in intermittent episodes of gastrointestinal bleeding. 
  • This condition typically occurs in the cecum and right colon, although it can affect any part of the colon. Angiodysplasia is more commonly observed in older individuals, especially those over the age of 60, although it can occasionally affect younger people as well. 

Epidemiology

  • Prevalence: 
  • Angiodysplasia is present in 0.8% of healthy individuals over 50 who are having a screening colonoscopy. 
  • Angiodysplasia of the colon is more commonly seen in older adults, especially those over 50 years of age. 
  • It’s regarded as one of the most frequent reasons for elderly people experience lower gastrointestinal haemorrhage. 
  • Risk Factors: 
  • Age is a significant risk factor, with the condition being more prevalent in the elderly. 
  • Certain medical conditions might increase the risk of developing angiodysplasia, such as renal failure, aortic stenosis, and von Willebrand disease. 
  • It has been associated with conditions that affect blood vessel integrity, such as hereditary hemorrhagic telangiectasia. 
  • Gender: 
  • There appears to be no significant gender predilection for angiodysplasia of the colon, as it affects both males and females equally. 

Anatomy

Pathophysiology

  • Abnormal Blood Vessels: The primary cause of angiodysplasia is aberrant blood vessel development in the colon’s mucosal and submucosal layers. These vessels are fragile, dilated, and prone to bleeding. The exact reason for their development is not entirely clear, but it’s thought to be associated with age-related degenerative changes in the blood vessels. 
  • Hemodynamic Changes: Angiodysplasia is often linked to alterations in blood flow dynamics within the colon. Conditions that affect blood flow in the gastrointestinal tract, such as chronic low-grade ischemia or intermittent increased blood flow, can contribute to the development of these abnormal vessels. Changes in blood flow may result in localized areas of vascular dilation and subsequent weakening of vessel walls. 
  • Mechanical Stress: Chronic or repetitive mechanical stress on the blood vessels due to peristalsis may also play a role. The constant movement and pressure in the colon might contribute to the development of these abnormal vessels or exacerbate existing ones, making them more susceptible to rupture and bleeding. 
  • Age and Other Risk Factors: Angiodysplasia is more commonly seen in older individuals, suggesting an association with the aging process. Other risk factors, such as kidney disease, aortic stenosis, and von Willebrand disease, may increase the likelihood of developing angiodysplasia. These conditions can affect blood vessel health and contribute to the development or worsening of abnormal blood vessels in the colon. 

Etiology

  • Age-related changes: Angiodysplasia is more common in older adults, and age-related degenerative changes in the blood vessels of the colon may play a role. As people age, the blood vessels in the colon can become fragile and prone to developing abnormal, dilated vessels. 
  • Hemodynamic changes: Abnormalities in blood flow within the blood vessels of the colon may contribute to the development of angiodysplasia. Chronic low-grade obstruction or changes in blood pressure within the vessels may lead to dilation and formation of abnormal blood vessels. 
  • Gastrointestinal diseases: Certain gastrointestinal conditions, such as chronic inflammatory disorders, can predispose individuals to angiodysplasia. These conditions may cause chronic inflammation or changes in the intestinal lining, increasing the risk of vascular abnormalities. 
  • Other factors: Some theories suggest that changes in platelet function, clotting factors, or abnormalities in the wall of the blood vessels may contribute to the development of angiodysplasia. Additionally, conditions associated with chronic kidney disease, von willebrand disease, or aortic stenosis may also increase the risk of angiodysplasia. 

Genetics

Prognostic Factors

  • Most angiodysplasias 90% spontaneously stop bleeding, the prognosis for people with angiodysplasia is favourable. 

Clinical History

  • Age group 
  • Angiodysplasia of the colon typically affects older adults, commonly those who are over the age of 60. However, it can occur at any age. While it’s more prevalent in older individuals, it’s not exclusive to that age group. 

Physical Examination

  • Abdominal Examination: Palpating the abdomen to check for tenderness, masses, or abnormal growths. 
  • Rectal Examination: To look for any abnormalities in the rectum or blood in the stool, a digital rectal exam may occasionally be conducted. 
  • Laboratory Tests:  
  • Complete Blood Count: To check for anaemia symptoms brought on by prolonged bleeding. 
  • Coagulation Studies: To evaluate blood clotting factors. 
  • Imaging Studies: Depending on the severity and suspected extent of the condition, imaging tests may be recommended. 
  • Colonoscopy: This is a key diagnostic tool where a flexible tube with a camera colonoscope is inserted into the colon to visualize the area and potentially treat the angiodysplasia. 
  • CT Scan or MRI: These may be utilized to get detailed images of the gastrointestinal tract, especially if there are concerns about complications or to locate the bleeding source accurately. 

Age group

Associated comorbidity

  • Gastrointestinal Bleeding: Angiodysplasia is a common cause of lower gastrointestinal bleeding, resulting in symptoms such as rectal bleeding, blood in stools, or anemia due to chronic blood loss. 
  • Chronic Kidney Disease: There’s an observed association between angiodysplasia and CKD, possibly due to changes in blood flow dynamics and vessel fragility associated with kidney disease. 
  • Aging: Angiodysplasia is more prevalent among older individuals, especially those over the age of 60. It is considered a part of the aging process and might become more common as people get older. 
  • Heart conditions: There might be a link between angiodysplasia and certain heart conditions, particularly aortic stenosis. Abnormal blood flow dynamics can contribute to the development or worsening of angiodysplasia. 
  • Chronic conditions or medications: Some chronic conditions such as end-stage renal disease requiring dialysis or certain medications like nonsteroidal anti-inflammatory drugs might increase the risk of angiodysplasia or exacerbate its symptoms. 
  • Inflammatory Bowel Disease: Some research points to a possible connection between angiodysplasia and IBD, even though the exact relationship could be more precise. It is especially true when ulcerative colitis or Crohn’s disease involves the colon. 
  • Hereditary Haemorrhagic Telangiectasia: This is a rare genetic disorder that causes abnormal blood vessel formation. Angiodysplasia may be seen in individuals with HHT due to the inherent vascular abnormalities associated with this condition. 

Associated activity

Acuity of presentation

  • Chronic, Insidious Bleeding: Many cases involve slow, chronic bleeding over an extended period, leading to the gradual development of symptoms such as iron-deficiency anemia, fatigue, weakness, and sometimes occult blood in stools. 
  • Intermittent Episodes of Acute Bleeding: Some individuals may experience sudden and significant bleeding episodes, leading to the passing of bright red or maroon-colored blood in stools, which might be accompanied by symptoms of dizziness, light-headedness, or even fainting due to blood loss. 
  • Variable Severity: The severity of bleeding can vary widely. While some individuals may have minimal symptoms, others may experience severe or life-threatening bleeding requiring urgent medical attention and intervention. 
  • Asymptomatic Cases: In some instances, angiodysplasia of the colon might be incidentally discovered during imaging or colonoscopy for reasons unrelated to bleeding. These cases may not present any noticeable symptoms. 

Differential Diagnoses

  • Colorectal Cancer: Similar symptoms, such as changes in bowel habits and rectal bleeding, might be present in colorectal cancers. Diagnostic tests like colonoscopy, biopsy, and imaging studies help differentiate between cancer and angiodysplasia. 
  • Inflammatory Bowel Disease: Abdominal pain, bowel irregularities, and gastrointestinal bleeding can all be symptoms of conditions like Crohn’s disease and ulcerative colitis. Distinguishing between IBD and angiodysplasia often requires a combination of endoscopic examinations, imaging, and histological analysis. 
  • Diverticulitis: Diverticula, pouches that form in the colon wall, can cause similar symptoms, including rectal bleeding and abdominal pain. Imaging studies like CT scans can help identify diverticula and differentiate them from angiodysplasia. 
  • Ischemic Colitis: Ischemic colitis can result from reduced blood flow to the colon because of artery occlusion, causing symptoms such as abdominal pain, bloody stools, and diarrhea. Radiological studies and colonoscopy may aid in diagnosing ischemic colitis. 
  • Hemorrhoids: During bowel movements, enlarged veins around the rectum or anus can cause discomfort and bleeding, mimicking symptoms of angiodysplasia. Physical examination and anoscopy help differentiate hemorrhoids from angiodysplasia.

Treatment Paradigm

  • Observation and Monitoring: 
  • For mild cases with minimal or no symptoms, especially in asymptomatic individuals or those with mild intermittent bleeding, a “watchful waiting” approach might be adopted. Regular monitoring through periodic check-ups or colonoscopies may be recommended to assess the progression of the condition. 
  • Medications: 
  • Iron supplements: Angiodysplasia-related bleeding can lead to iron-deficiency anemia. Iron supplements may be prescribed to manage anemia and replenish iron stores. 
  • Hormonal therapy: In some cases, hormonal medications like estrogen-progesterone or desmopressin may help reduce bleeding by promoting clotting. 
  • Endoscopic Interventions: 
  • Endoscopic procedures, such as colonoscopy, can be utilized both for diagnosis and treatment. 
  • Endoscopic cauterization: Thermal techniques or electrocoagulation may be employed to seal off bleeding vessels during a colonoscopy. 
  • Endoscopic band ligation: Placing rubber bands around bleeding vessels to constrict them and halt bleeding. 
  • Injection therapy: Injection of medications or solutions into the affected blood vessels to stop bleeding. 
  • Surgical Interventions: 
  • For cases where endoscopic procedures fail to control severe bleeding or in situations of recurrent bleeding, surgical options might be considered. 
  • Colectomy: In situations that are severe or unresponsive, surgical excision of a portion or the entire colon may be advised. 
  • Newer Therapies: 
  • Advanced techniques, such as capsule endoscopy, where a pill-sized camera is swallowed to visualize the small intestine, might aid in identifying angiodysplastic lesions not easily seen through traditional methods. 
  • Other emerging therapies or investigational approaches, like angiographic embolization, are under research for their efficacy in managing angiodysplasia-related bleeding. 
  • Supportive Care: 
  • In circumstances of severe bleeding, blood transfusions could be required to replenish lost blood and stabilise the patient’s condition. 
  • Fluid and electrolyte replacement might be required if there’s substantial blood loss.
