K55.011
Focal (segmental) acute (reversible) ischemia of small intestine
Clinical Classification Guidelines
Medical Intelligence & Overview
Focal segmental acute ischemia of the small intestine is a condition where a localized area of the small intestine temporarily receives insufficient blood flow. This lack of blood supply can cause tissue damage but is typically reversible if diagnosed and treated promptly. The condition is often associated with acute symptoms that require immediate medical attention to prevent complications such as tissue death or perforation.
Causes & Symptoms
Clinical Causes: Blood clots blocking blood flow in mesenteric arteries or veins Atherosclerosis leading to narrowing of blood vessels Embolisms originating from other parts of the body Low blood pressure or shock reducing overall blood flow Vasospasm or sudden constriction of blood vessels Inflammatory conditions affecting blood vessels Surgical procedures or trauma causing vascular injury
Key Symptoms: Sudden onset abdominal pain, often severe Nausea and vomiting Abdominal tenderness and swelling Signs of bowel dysfunction such as diarrhea or constipation Possible bleeding in the gastrointestinal tract Fever and elevated heart rate in some cases
Diagnostic & Treatment
Diagnosis Path: Blood tests to identify signs of inflammation or tissue damage Imaging studies such as computed tomography (CT) angiography to visualize blood flow Doppler ultrasound to assess blood vessel patency Possibly a contrast study or endoscopy for direct visualization of the intestine Blood gas analysis if metabolic disturbances are suspected
Treatment Protocols: Initial stabilization with intravenous fluids to improve blood pressure Administration of anticoagulants or thrombolytic agents if blood clots are involved Surgical intervention may be necessary to remove necrotic tissue or restore blood flow Monitoring and supportive care including pain management Addressing underlying causes such as managing blood vessel diseases or systemic conditions
