I82.A22 Chronic embolism and thrombosis of left axillary vein

Name of the Condition

• Chronic Embolism and Thrombosis of Left Axillary Vein

Summary

Chronic embolism and thrombosis of the left axillary vein refers to the long-term presence or recurrence of a blood clot in the left axillary vein, which can obstruct blood flow from the arm and shoulder. This condition may lead to persistent symptoms or complications due to ongoing venous obstruction or damage.

Causes

The condition may result from factors that promote blood clotting, such as injury to the vein wall, prolonged immobility, or underlying disorders that increase clotting propensity. Surgical procedures, trauma, or inflammation of the left axillary vein can also contribute to clot formation, with chronicity developing if the clot persists or recurs.

Risk Factors

• Prolonged immobility or bed rest
• Recent surgery or trauma to the arm/shoulder
• Cancer or cancer treatments
• Obesity
• Smoking
• Pregnancy and postpartum period
• Family history of thrombosis
• Use of hormonal contraceptives or hormone replacement therapy

Symptoms

• Swelling in the left arm or shoulder
• Pain or tenderness in the affected area
• Redness or warmth over the clot site
• Visible enlarged veins
• Skin discoloration or ulceration in chronic cases

Diagnosis

Diagnosis typically involves imaging studies like ultrasound, CT, or MRI to visualize the clot, along with blood tests (e.g., D-dimer) to assess clotting activity. Clinical evaluation of symptoms and risk factors also supports the diagnosis.

Treatment Options

Treatment may include anticoagulant medications to prevent clot growth or recurrence, compression therapy to reduce swelling, and pain management. In some cases, thrombolytic therapy or surgical intervention may be considered for severe obstruction.

Prognosis and Follow-Up

Prognosis depends on the extent of venous damage and response to treatment. Regular follow-up is important to monitor for recurrence or complications, such as post-thrombotic syndrome.

Complications

Potential complications include post-thrombotic syndrome (chronic pain, swelling, or skin changes), pulmonary embolism, or venous insufficiency.

Lifestyle & Prevention

• Maintain mobility to reduce clot risk
• Avoid prolonged immobility, especially during travel or recovery
• Manage underlying conditions like obesity or smoking
• Follow prescribed anticoagulant therapy as directed

When to Seek Professional Help

Seek medical attention if you experience sudden or worsening swelling, pain, redness, or warmth in the left arm, or if symptoms persist despite treatment.

Tips for Medical Coders

Document the laterality (left axillary vein) and chronicity clearly in the medical record. Ensure clinical documentation supports the chronic nature of the condition to justify the I82.A22 code.
