Laboratory Studies
- Complete blood cell count, platelet count, and basic chemistry profile: Results should be within reference ranges; however, abnormalities in these parameters could be early indicators of dehydration or a hypercoagulable state.
- Prothrombin time, activated partial thromboplastin time: Again, results should be within reference ranges; however, they should be checked in order to assess the patient's coagulation profile.
- Antithrombin III level: In a hypercoagulable state, the antithrombin III level is low.
- Alpha-macroglobulin, plasminogen levels: Low levels indicate a prothrombotic state.
- Fibrinogen, factor VII, and factor VIII levels: Elevated levels indicate a prothrombotic state.
- Protein C and S levels: Abnormalities in these parameters indicate a chronic inflammatory state.
- Factor V Leiden and factor II C20210-a levels should also be assessed.
Imaging Studies
- Arteriography: This is a vital component of the evaluation process in order to determine the anatomical aberrations of the arterial system and to plan possible therapeutic interventions. Include a venous runoff as well because accompanying subclavian vein pathology should not be overlooked.
- Computerized axial tomography scanning: This study is of assistance in defining bony pathology of the thoracic outlet that may contribute to occlusion of the subclavian artery.
- Magnetic resonance arteriography: This study is a useful modality for defining subclavian artery anatomy and pathology.[5]
Other Tests
- Echocardiography should be obtained in order to evaluate possible sources of arterial emboli.
