Pulmonary Circulation Obstruction

Study summary

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.

Inclusion Criteria: * Patient addressed to nuclear medicine department of Saint-Etienne public hospital for V/Q pulmonary SPECT-CT assess to rule out perfusion obstruction, admitted for a suspicion of pulmonary hypertension (PH), or a persistent dyspnea after PE * Patient affiliated ou beneficiary of social security. Exclusion Criteria: * Pregnant patient. * Patient addressed to nuclear medicine department for acute pulmonary embolism. * Impossibility of the entire protocol acquisitions realization.

Primary outcome measure(s)

  • RPVO (%) — At inclusion
    Evaluation of the RPVO establish with Meyer score (planar scintigraphy, 2D). The higher the percentage, the greater the obstruction of the lung
  • Segmental visual score — At inclusion
    Evaluation of segmental visual score (SPECT-CT , 3D) The higher the percentage, the greater the obstruction of the lung
