S35.238 Other injury of inferior mesenteric artery

Name of the Condition

• Other injury of inferior mesenteric artery

Summary

An other injury of the inferior mesenteric artery refers to damage to the vascular structure supplying the lower abdominal organs, distinct from lacerations or specific trauma types. This condition requires evaluation to assess vascular integrity and prevent complications such as hemorrhage or ischemia of the supplied organs.

Causes

Direct trauma to the abdomen, such as from motor vehicle accidents, falls, or penetrating injuries. Blunt force impact or crush injuries that disrupt the arterial wall. Iatrogenic causes, including surgical procedures or medical interventions in the abdominal region.

Risk Factors

• Participation in high-risk activities with potential for abdominal trauma.
• Occupations involving exposure to machinery or environments with crush hazards.
• Pre-existing vascular conditions that may predispose to injury.
• Advanced age, which can affect tissue elasticity and healing.

Symptoms

• Severe lower abdominal pain.
• Signs of internal bleeding, such as hypotension or tachycardia.
• Abdominal distension or rigidity.
• Altered skin temperature or sensation in the extremities.
• Possible pulsatile mass or hematoma in the lower abdomen.

Diagnosis

Physical examination to assess for signs of trauma or hemodynamic instability. Imaging studies, such as CT angiography, to visualize vascular damage. Laboratory tests to evaluate blood loss or organ function.

Treatment Options

• Surgical repair or revascularization to restore arterial flow.
• Endovascular interventions, such as embolization or stenting, for selected cases.
• Supportive care, including fluid resuscitation and hemodynamic monitoring.
• Management of associated injuries or complications.

Prognosis and Follow-Up

Prognosis depends on the extent of injury, timeliness of intervention, and presence of complications. Follow-up may include imaging to assess vascular healing and monitoring for long-term ischemic or hemorrhagic risks.

Complications

• Severe hemorrhage leading to hypovolemic shock.
• Ischemia or infarction of supplied abdominal organs.
• Infection or abscess formation at the injury site.
• Long-term vascular dysfunction or aneurysm development.

Lifestyle & Prevention

• Use protective equipment during high-risk activities.
• Follow safety protocols in occupational settings with trauma risks.
• Seek prompt medical evaluation after abdominal trauma.
• Manage underlying vascular conditions to reduce injury susceptibility.

When to Seek Professional Help

Seek immediate medical attention for severe abdominal pain, signs of internal bleeding, or trauma to the lower abdomen. Persistent symptoms or concerns about vascular integrity also warrant professional evaluation.

Tips for Medical Coders

Document the specific nature of the injury (e.g., contusion, rupture, or other specified type) and any associated trauma or iatrogenic causes. Ensure clinical correlation with imaging or procedural notes to support code assignment.
