S35.532 Injury of left uterine artery

Name of the Condition

• Injury of left uterine artery

Summary

An injury of the left uterine artery involves damage to the vascular structure supplying blood to the left side of 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 evaluate vascular damage and identify bleeding or ischemia. Laboratory tests to assess blood loss and coagulation status.

Treatment Options

• Immediate stabilization of hemodynamic status, including fluid resuscitation or blood transfusion if needed.
• Surgical intervention to repair or ligate the injured artery, depending on the severity of the injury.
• Endovascular techniques, such as embolization, to control bleeding in select cases.
• Monitoring for complications and supportive care during recovery.

Prognosis and Follow-Up

Prognosis depends on the extent of the injury, timeliness of treatment, and presence of comorbidities. Most patients recover with appropriate management, but severe cases may require prolonged monitoring. Follow-up imaging or clinical evaluation may be needed to assess healing and detect late complications.

Complications

• Persistent or recurrent hemorrhage requiring further intervention.
• Ischemia or infarction of uterine tissue due to compromised blood flow.
• Infection at the injury site or related to surgical repair.
• Long-term vascular sequelae, such as aneurysm formation or chronic pain.

Lifestyle & Prevention

• Use protective equipment during high-risk activities to minimize trauma risk.
• Adhere to safety protocols in occupational settings with crush hazards.
• Ensure careful surgical technique during pelvic procedures to reduce iatrogenic injury.
• 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, unexplained bruising, signs of internal bleeding (e.g., dizziness, fainting), or sudden changes in vital signs after trauma or pelvic procedures.

Tips for Medical Coders

Code S35.532 is specific to injury of the left uterine artery. Document the mechanism of injury (e.g., trauma, iatrogenic) and any associated complications to support accurate coding. Ensure specificity in clinical notes to differentiate from other pelvic vascular injuries.
