Residual Embolism Evaluated With Single Photon Emission Computed Tomography

Recruiting now

Conditions studied: Pulmonary Circulation Obstruction

In brief

Major progress achieved in diagnostic and therapeutic strategies has substantially improved the short-term prognosis of patients with pulmonary embolism (PE). These improvements have led to a shift from an acute to a chronic condition of venous thromboembolism, justifying the recent development of Chronic Thrombo-embolic Disease (CTED). In most of the situations, it is due to a residual pulmonary vascular obstruction (RPVO) which can be assessed by pulmonary scintigraphy.
