I82.A11 Acute embolism and thrombosis of right axillary vein

Name of the Condition

• Acute Embolism and Thrombosis of Right Axillary Vein

Summary

Acute embolism and thrombosis of the right axillary vein refers to the sudden formation or lodgment of a blood clot in the right axillary vein, which can obstruct blood flow from the arm and shoulder. This condition may lead to localized symptoms or systemic complications depending on clot size and progression.

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 right axillary vein can also contribute to clot formation.

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 right arm or shoulder
• Pain or tenderness in the affected area
• Redness or warmth over the clot site
• Visible enlarged veins
• Possible 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 guides diagnosis.

Treatment Options

Treatment may include anticoagulant medications to prevent clot growth, thrombolytic therapy to dissolve the clot, or surgical intervention in severe cases. Compression garments or elevation of the affected arm may also be recommended.

Prognosis and Follow-Up

Prognosis depends on clot size, treatment response, and underlying risk factors. Follow-up may involve monitoring for recurrence, managing risk factors, and regular imaging to assess vein patency.

Complications

Potential complications include post-thrombotic syndrome (chronic pain, swelling), pulmonary embolism, or recurrent thrombosis. Severe cases may lead to tissue damage or loss of function in the affected arm.

Lifestyle & Prevention

• Maintain mobility to reduce clot risk
• Avoid prolonged immobility during travel or recovery
• Manage underlying conditions (e.g., obesity, smoking)
• Follow prescribed anticoagulant therapy as directed

When to Seek Professional Help

Seek immediate care for sudden severe pain, swelling, or discoloration in the right arm, or if symptoms worsen despite treatment. Prompt evaluation is critical to prevent complications.

Tips for Medical Coders

Document the acute nature of the condition and specify the right axillary vein involvement. Include details on diagnostic methods (e.g., imaging, labs) and treatment approaches to support code assignment. Ensure documentation aligns with clinical findings to justify the acute embolism and thrombosis diagnosis.
