S35.412S Laceration of left renal artery, sequela

Name of the Condition

• Laceration of left renal artery, sequela

Summary

A laceration of the left renal artery, sequela, refers to the residual effects or complications following a prior tear or cut in the blood vessel supplying the left kidney. This condition arises after the initial injury and may involve persistent vascular damage, impaired renal function, or related sequelae requiring ongoing evaluation and management.

Causes

The sequela results from a previous laceration of the left renal artery, which may have been caused by direct trauma (e.g., motor vehicle accidents, falls, penetrating injuries), blunt force impact, crush injuries, or iatrogenic events (e.g., surgical procedures). The residual effects stem from the initial injury's severity and healing process.

Risk Factors

• History of significant renal trauma or vascular injury.
• Incomplete healing or complications from the initial laceration.
• Pre-existing vascular conditions that may exacerbate residual damage.
• Delayed or inadequate initial treatment of the primary injury.

Symptoms

• Persistent or recurrent flank/abdominal pain.
• Reduced renal function (e.g., elevated creatinine, decreased urine output).
• Hypertension due to renal artery stenosis or impaired blood flow.
• Possible signs of chronic ischemia or atrophy of the left kidney.
• Recurrent bleeding or vascular complications.

Diagnosis

Clinical assessment of residual symptoms and history of prior renal artery laceration. Imaging studies (e.g., CT angiography, Doppler ultrasound) to evaluate vascular integrity and renal function. Laboratory tests to assess kidney function and detect ongoing complications.

Treatment Options

Management focuses on addressing residual vascular or renal issues, such as angioplasty, stenting, or surgical repair for persistent stenosis. Blood pressure control and renal function monitoring are critical. In severe cases, nephrectomy may be considered if the kidney is non-functional.

Prognosis and Follow-Up

Prognosis depends on the extent of residual damage and response to treatment. Regular monitoring of renal function, blood pressure, and vascular status is essential. Long-term follow-up may be required to manage chronic complications or prevent further deterioration.

Complications

• Chronic kidney disease or renal failure.
• Persistent hypertension.
• Vascular stenosis or aneurysm formation.
• Recurrent bleeding or thrombosis.
• Infection or abscess related to prior injury.

Lifestyle & Prevention

Maintain regular medical follow-up to monitor renal and vascular health. Control blood pressure and manage underlying conditions (e.g., diabetes) to reduce strain on the kidneys. Avoid activities that risk renal trauma if vascular integrity is compromised.

When to Seek Professional Help

Seek care if experiencing worsening flank pain, changes in urination, uncontrolled hypertension, or signs of infection (e.g., fever, chills). Prompt evaluation is necessary for new or worsening symptoms to prevent further renal or vascular damage.

Tips for Medical Coders

Code S35.412S is used for the sequela of a left renal artery laceration. Document the relationship to the prior injury, including the time frame and residual effects. Ensure clinical notes specify the nature of the sequela (e.g., vascular stenosis, renal dysfunction) to support coding accuracy.
