S35.533 Injury of unspecified uterine artery

Name of the Condition

• Injury of unspecified uterine artery

Summary

An injury of the unspecified uterine artery involves damage to the vascular structure supplying blood to the uterus, typically resulting from trauma or iatrogenic causes. This condition requires prompt evaluation to assess vascular integrity and prevent complications such as hemorrhage or ischemia.

Causes

Direct trauma to the pelvic region, such as from motor vehicle accidents, falls, or penetrating injuries. Blunt force impact or crush injuries that disrupt vascular integrity. Iatrogenic causes, including surgical procedures or medical interventions in the pelvic area, such as hysterectomy or cesarean section.

Risk Factors

• Participation in high-risk activities with potential for pelvic 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.
• Pregnancy or recent childbirth, which may alter pelvic vascular anatomy.

Symptoms

• Pain, swelling, or tenderness in the pelvic or lower abdominal region.
• Visible bruising or discoloration over the injured area.
• Signs of internal bleeding, such as hypotension or tachycardia.
• Altered skin temperature or sensation in the pelvic region.
• Possible hematoma or pulsatile mass at the injury site.

Diagnosis

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

Treatment Options

• Immediate stabilization of hemodynamic status, including fluid resuscitation or blood transfusion.
• Surgical intervention to repair or ligate the injured artery, if necessary.
• Endovascular techniques, such as embolization, to control bleeding.
• Monitoring for complications and supportive care.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and promptness of treatment. Follow-up may include imaging to assess healing and monitoring for delayed complications. Long-term outcomes vary based on the extent of vascular damage and associated injuries.

Complications

• Persistent hemorrhage or hematoma formation.
• Ischemia or infarction of uterine tissue.
• Infection at the injury site.
• Vascular sequelae, such as aneurysm or pseudoaneurysm formation.

Lifestyle & Prevention

• Use protective measures during high-risk activities to minimize pelvic trauma.
• Ensure proper medical supervision during pelvic surgeries or interventions.
• Maintain overall vascular health through regular check-ups and management of underlying conditions.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pelvic pain, signs of internal bleeding (e.g., dizziness, fainting), or trauma to the pelvic region. Prompt evaluation is critical to prevent life-threatening complications.

Tips for Medical Coders

Document the specific laterality (right, left, or unspecified) of the uterine artery injury when available. Ensure clinical documentation supports the diagnosis and any associated procedures or complications. Verify that the code aligns with the reported injury details to ensure accurate coding.
