: Obstruction causes a ventilation-to-perfusion ( ) mismatch, leading to hypoxemia and respiratory distress. Diagnostic Framework

: Tools such as the Wells Score or Geneva Score assess pre-test probability. The PERC (Pulmonary Embolism Rule-out Criteria) is used to safely exclude PE in low-risk patients without further testing. Download Embolie pulmonaire aiguГ« pdf

: D-dimer testing is highly sensitive for ruling out PE in low-to-intermediate risk patients. Cardiac biomarkers like Troponin and BNP help assess myocardial injury and RV strain. : D-dimer testing is highly sensitive for ruling

) scans are alternatives for patients with renal issues or contrast allergies. Management and Treatment it increases pulmonary vascular resistance

: When thrombolysis is contraindicated or fails, options include catheter-directed thrombectomy or surgical embolectomy. Prognosis and Follow-Up

: Once a clot lodges in the pulmonary vascular bed, it increases pulmonary vascular resistance, which can lead to acute right ventricular (RV) failure and hemodynamic collapse.

: For high-risk (hemodynamically unstable) patients, systemic thrombolysis (e.g., Alteplase) is recommended to rapidly dissolve the clot.
