I82.A23 Chronic embolism and thrombosis of axillary vein, bilateral

Name of the Condition

• Chronic Embolism and Thrombosis of Axillary Vein, Bilateral

Summary

Chronic embolism and thrombosis of the axillary vein, bilateral, refers to the persistent or recurrent presence of blood clots in both axillary veins. This condition can obstruct blood flow from the arms and shoulders, potentially leading to ongoing symptoms or complications due to 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 axillary veins can also contribute to clot formation, with chronicity developing if the clots persist or recur.

Risk Factors

• Prolonged immobility or bed rest
• Recent surgery or trauma to the arms/shoulders
• 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 both arms or shoulders
• Pain or tenderness in the affected areas
• Redness or warmth over the clot sites
• Visible enlarged veins
• Skin discoloration or ulceration in chronic cases

Diagnosis

Diagnosis typically involves imaging studies like ultrasound, CT, or MRI to visualize the clots, along with blood tests (e.g., D-dimer) to assess clotting activity. Clinical evaluation of symptoms and risk factors also plays a key role in confirming the condition.

Treatment Options

Treatment may include anticoagulant medications to prevent clot growth or new clots, compression therapy to reduce swelling, and pain management. In some cases, thrombolytic therapy or surgical intervention may be considered to remove or dissolve the clots.

Prognosis and Follow-Up

Prognosis depends on the severity of the clots and response to treatment. Regular follow-up with imaging and blood tests may be necessary to monitor for recurrence or complications. Long-term management often focuses on preventing future clots.

Complications

Potential complications include post-thrombotic syndrome (chronic pain, swelling, or skin changes), pulmonary embolism, or recurrent thrombosis. Severe cases may lead to venous insufficiency or tissue damage.

Lifestyle & Prevention

• Maintain regular physical activity to promote circulation
• Avoid prolonged immobility; move or stretch during long periods of sitting or lying down
• Stay hydrated and avoid smoking
• Follow medical advice for managing underlying conditions (e.g., cancer, hormonal therapies)
• Use compression garments if recommended by a healthcare provider

When to Seek Professional Help

Seek medical attention if you experience sudden or worsening swelling, pain, redness, or warmth in both arms, or if symptoms interfere with daily activities. Prompt evaluation is important to prevent complications.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record, as this is essential for accurate coding. Ensure clinical notes specify the chronicity and presence of embolism or thrombosis in both axillary veins to support the use of code I82.A23.
