Superior Vena Cava Obstruction

Aka: Superior Vena Cava Obstruction, Superior Caval Vein Obstruction, Superior Vena Cava Occlusion, Superior Vena Cava Syndrome
  1. Pathophysiology
    1. Azygous vein may provide some collateral drainage
    2. Superior Vena Cava Obstruction to flow
      1. Vena cava thrombosis
      2. Mediastinal mass gradually compresses superior vena cava, blocking entry into right atrium
        1. Results in retrograde flow and regional edema
  2. Causes
    1. Malignancy
      1. Bronchogenic Carcinoma (80%)
      2. Malignant Lymphoma (15%)
      3. Metastatic Disease (to lung, mediastinum or lymph nodes)
        1. Breast adenocarcinoma
        2. Testicular seminoma
    2. Benign Disease (Rare)
      1. Mediastinal fibrosis
        1. Idiopathic
        2. Histoplasmosis
        3. Actinomycosis
        4. Tuberculosis
      2. Vena Cava thrombosis
        1. Idiopathic
        2. Behcet's Syndrome
        3. Polycythemia Vera
        4. Paroxysmal Nocturnal Hemoglobinuria
        5. Long-term venous catheters, shunts or Pacemakers
      3. Benign Mediastinal tumor
        1. Aortic aneurysm
        2. Dermoid tumor
        3. Goiter
        4. Sarcoidosis

    1. Dyspnea (50%)
    2. Neck and facial swelling (40%)
    3. Swelling of trunk and upper extremities (40%)
    4. Choking sensation
    5. Hoarseness

    8. Chest Pain
    9. Shoulder Pain
    10. Cough
    11. Lacrimation
    12. Dysphagia
  4. Signs
    1. Thoracic vein distention (65%)
    2. Neck vein distention (55%)
    3. Facial edema (55%)
    4. Tachypnea (40%)
    5. Plethora of the face and Cyanosis (15%)
    6. Edema of upper extremities (10%)
    7. Paralysis of Vocal Cords (3%)
    8. Horner's Syndrome (3%)
    9. Distended antecubital veins
  5. Associated Conditions
    1. Spinal Cord compression
  6. Radiology
    1. Chest XRay shows mass in 90%
      1. Right superior mediastinum (75%)
      2. Hilar Adenopathy (50%)
      3. Right Pleural Effusion (25%)
    2. Chest CT
  7. Management
    1. Identify mass etiology
    2. Consult Oncology and Cardiothoracic Surgery acutely
      1. Palliative CareConsultation once stabilized
    3. Supportive care
      1. ABC Management
      2. Corticosteroids
      3. Diuretics
      4. Elevate the head of the bed
    4. Reduction in mass size
      1. Radiation Therapy
      2. Chemotherapy
      3. Surgical decompression
    5. Consider Anticoagulation
    6. Intravenous stenting
      1. Common acute management
      2. Improvement is seen within days
      3. Effective even when tumor mass is not reducible
  8. Prognosis
    1. Poor prognostic sign
      1. Predicts 90% mortality in 3 years
      2. Median survival: 6 months

Superior Vena Cava Syndrome (C0038833)

Definition (NCI_NCI-GLOSS) A condition in which a tumor presses against the superior vena cava (the large vein that carries blood from the head, neck, arms, and chest to the heart). This pressure blocks blood flow to the heart and may cause coughing, difficulty in breathing, and swelling of the face, neck, and upper arms.
Definition (NCI_CTCAE) A disorder characterized by obstruction of the blood flow in the superior vena cava. Signs and symptoms include swelling and cyanosis of the face, neck, and upper arms, cough, orthopnea and headache.
Definition (NCI) Obstruction of the blood flow in the superior vena cava caused by a malignant neoplasm, thrombosis, or aneurysm. It is a medical emergency requiring immediate treatment. Signs and symptoms include swelling and cyanosis of the face, neck, and upper arms, cough, orthopnea, and headache.
Definition (MSH) A condition that occurs when the obstruction of the thin-walled SUPERIOR VENA CAVA interrupts blood flow from the head, upper extremities, and thorax to the RIGHT ATRIUM. Obstruction can be caused by NEOPLASMS; THROMBOSIS; ANEURYSM; or external compression. The syndrome is characterized by swelling and/or CYANOSIS of the face, neck, and upper arms.
