S35.535 Injury of left uterine vein

Name of the Condition

• Injury of left uterine vein

Summary

An injury of the left uterine vein involves damage to the vascular structure draining blood from 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 visualize vascular damage and bleeding. Laboratory tests to evaluate blood loss and coagulation status.

Treatment Options

• Immediate stabilization of hemodynamics, including fluid resuscitation and blood transfusion if needed.
• Surgical intervention to repair or ligate the injured vein, depending on the extent of damage.
• Endovascular techniques, such as embolization, for selected cases to control bleeding.
• Close monitoring in a critical care setting for ongoing hemodynamic assessment.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timeliness of treatment. Most patients recover with appropriate management, but complications like chronic pain or vascular insufficiency may occur. Follow-up imaging and clinical evaluation are recommended to assess healing and detect late complications.

Complications

• Persistent hemorrhage or hematoma formation.
• Ischemic injury to the uterus or adjacent structures.
• Infection at the injury site.
• Chronic pelvic pain or vascular insufficiency.
• Thromboembolic events due to altered blood flow.

Lifestyle & Prevention

• Use protective gear during high-risk activities to minimize trauma risk.
• Follow post-surgical care instructions to reduce iatrogenic injury risk.
• Maintain overall vascular health through regular exercise and a balanced diet.
• Avoid activities that increase pelvic injury risk during pregnancy or postpartum recovery.

When to Seek Professional Help

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

Tips for Medical Coders

Document the laterality (left) and specify the vascular structure (uterine vein) to ensure accurate coding. Include details of the injury mechanism (trauma vs. iatrogenic) and any associated complications to support code assignment. Verify that the injury is not better classified under a more specific code for uterine artery or other pelvic vascular injuries.
