ABSTRACT
Diagnosis of deep vein thrombosis (DVT) depends mainly upon three clinical tools: venous compression ultrasonography (US), assessment of prior clinical probability (PCP), and measurement of fibrin D-Dimer (DD). In suspected pulmonary embolism (PE), the same tools can be applied, in addition to ventilation! perfusion lung scan (V!Q scan). In a few patients, venography (suspected DVT) or pulmonary angiography (suspected PE) may also be required.
