K55.041 Focal (segmental) acute infarction of large intestine

Name of the Condition

• Focal (Segmental) Acute Infarction of Large Intestine
• ICD-10 Code: K55.041

Summary

Focal (segmental) acute infarction of the large intestine is a sudden, localized loss of blood flow resulting in tissue death in a specific segment of the colon. This condition requires prompt evaluation to prevent complications and guide appropriate management.

Causes

Sudden occlusion of blood vessels supplying a segment of the large intestine, such as arterial or venous thrombosis, embolism, or non-occlusive ischemia, can lead to focal infarction. Underlying mechanisms may include blockages, reduced perfusion, or vascular compression affecting a specific colonic region.

Risk Factors

• Advanced age.
• Cardiovascular disease.
• Recent abdominal surgery or trauma.
• Dehydration or hypotension.
• Medications affecting vascular tone.
• Inflammatory bowel disease.

Symptoms

• Sudden, localized abdominal pain.
• Nausea or vomiting.
• Bloody or dark stools.
• 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 in the affected segment.

Treatment Options

• Restoring blood flow through medications or interventions.
• Surgical repair for severe cases.
• Supportive care, including fluid management and infection control.
• Segmental resection if necrosis is extensive.

Prognosis and Follow-Up

Outcomes depend on early intervention and underlying causes. Regular monitoring is essential to detect recurrence or complications, with follow-up imaging or endoscopy as needed.

Complications

• Intestinal necrosis or perforation.
• Sepsis or systemic infection.
• Stricture formation.
• Chronic abdominal pain.

Lifestyle & Prevention

• Maintain cardiovascular health through diet and exercise.
• Stay hydrated, especially during illness or heat exposure.
• Manage chronic conditions like diabetes or hypertension.
• Avoid medications that may reduce intestinal blood flow without medical guidance.

When to Seek Professional Help

Seek immediate medical attention for sudden, severe abdominal pain, bloody stools, or signs of infection (e.g., fever, chills). Prompt evaluation is critical to prevent life-threatening complications.

Tips for Medical Coders

Document the specific segment of the large intestine affected (e.g., ascending, transverse, descending, sigmoid, or rectum) and confirm acute infarction. Ensure clinical correlation with imaging or endoscopic findings to support the diagnosis.
