K55.1
Chronic vascular disorders of intestine
Clinical Classification Guidelines
Inclusion Terms
- Chronic ischemic colitis
- Chronic ischemic enteritis
- Chronic ischemic enterocolitis
- Ischemic stricture of intestine
- Mesenteric atherosclerosis
- Mesenteric vascular insufficiency
Medical Intelligence & Overview
Chronic vascular disorders of the intestine encompass a group of conditions characterized by reduced blood flow to the gastrointestinal tract. These conditions, including chronic ischemic colitis, enteritis, and enterocolitis, involve the gradual narrowing or blockage of blood vessels supplying the intestines. Over time, decreased blood supply can lead to tissue damage, discomfort, and complications such as strictures or bowel narrowing. These disorders often develop slowly and can significantly impact digestion and overall health if not managed appropriately.
Causes & Symptoms
Clinical Causes: Atherosclerosis affecting mesenteric arteries, leading to narrowing or blockage Progressive build-up of fatty deposits within blood vessel walls Blood clots or emboli obstructing intestinal blood flow Low blood pressure or hypoperfusion conditions Occlusion resulting from inflammatory or autoimmune diseases impacting blood vessels Chronic conditions causing blood vessel constriction or spasm
Key Symptoms: Intermittent abdominal pain, often after eating (postprandial pain) Unintended weight loss due to pain during meals Nausea and vomiting in severe cases Occasional diarrhea or changes in bowel habits Feeling of abdominal fullness or bloating Signs of intestinal ischemia, such as bleeding or tissue damage, in advanced stages
Diagnostic & Treatment
Diagnosis Path: Doppler ultrasound to assess blood flow in mesenteric vessels Computed tomography angiography (CTA) or magnetic resonance angiography (MRA) for detailed vascular imaging Conventional angiography to visualize blood vessel narrowing or blockages Barium studies of the gastrointestinal tract to observe structural changes Blood tests to evaluate for signs of anemia or inflammation Biopsy or endoscopy in some cases to examine tissue integrity
Treatment Protocols: Lifestyle modifications such as smoking cessation, balanced diet, and managing cholesterol levels Medications to improve blood flow, including vasodilators Antiplatelet or anticoagulant therapy to prevent clot formation Surgical intervention in cases of severe artery obstruction, such as bypass surgery or endovascular procedures Treating underlying conditions like atherosclerosis or autoimmune disorders Nutritional support and dietary adjustments to reduce gastrointestinal strain
