• Anemia

  Older people may have symptoms such as: Weakness Fatigue Shortness of breath due to anemia They may not have bleeding directly from the colon. [ufhealth.org]

  The patient presented with anemia unexpectedly before her aortic valve replacement. Colon fiberscopy revealed that colonic angiodysplasia was responsible for the bleeding. [ncbi.nlm.nih.gov]

  Tachycardia ( rapid heart rate ) and hypotension are signs of significant blood loss or long standing anemia and need to be assessed immediately. [healthhype.com]

  Treatment depends on whether the abnormal blood vessels are bleeding, and if you have anemia. In most cases, people only need treatment if the abnormal blood vessels are bleeding or they have anemia. [gandhofcny.com]

• Asymptomatic

  OBJECTIVE: The prevalence of colonic angiodysplasia (AD) among healthy asymptomatic people is unknown, and the natural history of these lesions has not been clearly defined. [ncbi.nlm.nih.gov]

  We compared the UGIB group from angiodysplasia with an asymptomatic control group. The asymptomatic control group was composed of 58 individuals who had incidental findings of angiodysplasia in a health screening center, St. [kjim.org]

  Cases of angiodysplasia in individuals less than 40 years have been documented in the literature. [5], [10] It may be asymptomatic, or present with iron deficiency anemia or positive occult blood. [njcponline.com]

  The presentation of multiple myeloma can range from asymptomatic to severely symptomatic with complications requiring emergent treatment. [gastrointestinalatlas.com]

• Pallor

  On general physical examination, the patient had pallor but no jaundice or enlarged lymph nodes. Abdominal examination was unremarkable, no viscera or mass palpable. On digital rectal examination, no abnormality was detected. [ispub.com]

• Congestive Heart Failure

  Underlying comorbidities, such as chronic liver disease, chronic renal disease, congestive heart failure, hypertension, and diabetes mellitus, were not associated with UGIB from angiodysplasia. [kjim.org]

• Melena

  Black, tarry stools ( melena ) and occasional episodes of bright red blood rectal bleeding ( hematochezia ) may be the only obvious signs of angiodysplasia. [healthhype.com]

  Overt bleeding consisted of hematemesis in 3 cases, melena in 34 cases and hematochezia in 18 cases.The sites involved in angiodysplastic lesions were: gastric in 18 cases (26%), small bowel 14 (20%), colon 53 (77%), including predominantly the right [latunisiemedicale.com]

  The patient was in good health with no history of GI bleeding, such as melena or hematochezia. He had no symptoms. Regarding laboratory findings, his hemoglobin was 14.7 g/dL and hematocrit was 42.3%. [saudijgastro.com]

  The severity of bleeding ranges from minor, but chronic upper GI blood loss to severe melena and hematemesis that leads to anemia and requires blood transfusion. [bmcgastroenterol.biomedcentral.com]

  Signs and symptoms [ edit ] Although some cases present with black, tarry stool ( melena ), the blood loss can be subtle, with the anemia symptoms predominating. Fecal occult blood testing is positive when bleeding is active. [en.wikipedia.org]

• Hematochezia

  There was no anorexia, abdominal swelling, diarrhea, or hematochezia. Abdomino-pelvic ultrasonography showed normal findings. [njcponline.com]

  Black, tarry stools ( melena ) and occasional episodes of bright red blood rectal bleeding ( hematochezia ) may be the only obvious signs of angiodysplasia. [healthhype.com]

  Overt bleeding consisted of hematemesis in 3 cases, melena in 34 cases and hematochezia in 18 cases.The sites involved in angiodysplastic lesions were: gastric in 18 cases (26%), small bowel 14 (20%), colon 53 (77%), including predominantly the right [latunisiemedicale.com]

  Clinical presentation of UGIB from angiodysplasias is usually characterized by maroon-colored stool, melena, or hematochezia. Bleeding usually is self-limited, but it can be chronic, recurrent, or even acute and life threatening. [kjim.org]

• Vascular Disease

  You are more likely to have vascular disease as you get older. [icdlist.com]

  Atherosclerotic peripheral vascular disease is another comorbidity that could further damage the intestinal vessel walls, especially in older patients, compromising the microcirculation of the large bowel. [10], [11], [12], [13] In favor of the theory [sjkdt.org]

Endoscopic treatment resulted in a therapeutic success rate of 100 %, and no recurrence of bleeding was observed in 85 % of the patients (11/13) after treatment. [ncbi.nlm.nih.gov]

Removal of the entire right side of the colon (right hemicolectomy) is the treatment of choice for someone with this condition who continues to bleed at a dangerously quick rate, despite several treatments by angiography and colonoscopy.Hormonal therapy [medigoo.com]

In two others, the need for transfusions was lessened considerably after treatment. The last patient died of terminal cardiac failure. No complications occurred during treatment. [link.springer.com]

Outlook (Prognosis) People who have bleeding related to this condition despite having had colonoscopy, angiography, or surgery are likely to have more bleeding in the future. The outlook remains good if the bleeding is controlled. [ufhealth.org]

However, case reports exist of occurrence in young people. [44] Prognosis The prognosis in patients with angiodysplasia is favorable because most angiodysplasias spontaneously cease bleeding (90% of cases). [emedicine.medscape.com]

Etiology and pathogenesis are unknown. The diagnosis can be made with angiography based on the demonstration of a vascular tuft and early opacification of draining veins. Right hemicolectomy is the mode of therapy. [ncbi.nlm.nih.gov]

While there are recognized limitations to this technique, including the inability to detect active bleeding, this small study shows that helical CT angiography may have a role in the diagnostic evaluation of patients with lower GI bleeding of unclear etiology [aafp.org]

Etiology: Thought to be caused by the higher wall tension of cecum (due to larger diameter) and result from (intermittent) venous occlusion/focal dilation of vessels. [2] Gross Cecum - classic location. [librepathology.org]

Lesions are usually located in the right colon and, although the pathophysiology is unknown, most are probably acquired as the result of a degenerative process associated with aging. [ncbi.nlm.nih.gov]

Etiology and Pathophysiology Exact pathophysiology is unknown. Lesions develop from chronic, low-grade obstruction of submucosal veins as a result of increased smooth muscle contractility. [unboundmedicine.com]

Vascular ectasias also occur in association with a number of systemic diseases (eg, renal failure, cirrhosis, CREST syndrome [calcinosis cutis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, telangiectasias]—see Pathophysiology ) and after [merckmanuals.com]

Of note, the aforementioned pathophysiologic mechanisms responsible for the development of cecal lesions are unlikely to apply to lesions in the upper GI tract, despite being morphologically identical. [emedicine.medscape.com]
