Presentation

History

Patients may describe a history of trauma or, more frequently, strenuous use of the arm (>50% of cases). Common precipitating activities involve repeated hyperabduction and external rotation of the arm or backward and downward rotation of the shoulder. Causative activities may include participating in cricket, tennis, wrestling, lifting weights, water polo, gymnastics, baseball, or chopping wood.

Because the symptoms of subclavian stenosis are fairly dramatic, most patients present promptly to the emergency department, usually within 24 hours. They may report dull ache in the shoulder or axilla, and the pain often is worsened by activity. Conversely, rest and elevation often relieve the pain. Patients with catheter-associated axillary-subclavian vein thrombosis (ASVT) report similar symptoms of the ipsilateral arm or shoulder with the indwelling catheter.

Physical Examination

Not all patients with subclavian vein thrombosis are symptomatic. Those with symptoms may present with mild-to-moderate nonpitting edema and mild cyanosis of the hands and fingers on the affected side. Dilatation of subcutaneous collateral veins may be present over the upper arm and chest. This later sign may be the only clue to ASVT in otherwise asymptomatic patients with catheter-related venous thrombosis.

In a few cases, in which the diagnosis was missed or delayed or the patient presented late, the thrombus may have extended to the superior vena cava. These patients show most features of the superior vena cava syndrome, including face and neck swelling, periorbital edema, blurred vision, and some degree of facial cyanosis. [8]

Complications

Pulmonary embolism (PE) may occur in as many as 20-36% of patients. Stroke may occur as a manifestation of paradoxic embolism in the presence of a patent foramen ovale.

Other complications can include the following:

  • Chronic venous insufficiency
  • Phlegmasia cerulea dolens
  • Superior vena cava syndrome
  • Pulmonary hypertension
  • Right-side heart failure
  • Thoracic duct obstruction
  • Chylous pleural or pericardial effusion
  • Brachial plexopathy
