K55.022 Diffuse acute infarction of small intestine

Name of the Condition

• Diffuse Acute Infarction of Small Intestine
• ICD-10 Code: K55.022

Summary

Diffuse acute infarction of the small intestine is a sudden, widespread reduction in blood flow leading to tissue death (infarction) throughout the small bowel. This condition requires urgent medical attention to prevent life-threatening complications.

Causes

Sudden occlusion of blood vessels supplying the small intestine, such as arterial or venous thrombosis, embolism, or non-occlusive ischemia, can cause infarction. Underlying mechanisms may include blockages, reduced perfusion, or vascular compression.

Risk Factors

• Advanced age.
• Cardiovascular disease.
• Recent abdominal surgery or trauma.
• Dehydration or hypotension.
• Medications affecting blood flow.

Symptoms

• Sudden, severe abdominal pain.
• Nausea or vomiting.
• Bloody stools or melena.
• Abdominal distension.
• Fever or signs of infection.

Diagnosis

Clinical evaluation, imaging (e.g., CT angiography), and laboratory tests help identify vascular compromise. Endoscopy may assess mucosal integrity, and Doppler ultrasound or angiography can confirm infarction.

Treatment Options

• Restoring blood flow through medications or interventions.
• Surgical repair for severe cases.
• Supportive care, including fluid management and infection control.

Prognosis and Follow-Up

Outcomes depend on early intervention and the extent of tissue damage. Regular monitoring is essential to detect recurrence or complications.

Complications

• Intestinal necrosis or perforation.
• Sepsis.
• Multi-organ failure.

Lifestyle & Prevention

• Manage cardiovascular risk factors (e.g., hypertension, diabetes).
• Avoid dehydration and maintain adequate hydration.
• Follow post-surgical care guidelines to reduce thrombotic risk.

When to Seek Professional Help

Seek immediate medical attention for sudden, severe abdominal pain, especially with vomiting, bloody stools, or fever.

Tips for Medical Coders

Document the diffuse nature of the infarction and any associated complications. Ensure clinical documentation supports the diagnosis and treatment provided.
