: Obstruction causes a ventilation-to-perfusion ( ) mismatch, leading to hypoxemia and respiratory distress. Diagnostic Framework
Patients with a first episode of unprovoked PE usually require anticoagulation for at least 3 to 6 months. Extended therapy may be necessary if persistent risk factors exist. Long-term monitoring is essential to detect rare complications like , which can present as persistent breathlessness months after the initial event. Download Embolie pulmonaire aiguГ« pdf
Acute Pulmonary Embolism (PE) is a critical cardiovascular emergency characterized by the sudden obstruction of a pulmonary artery, typically by a blood clot originating from deep vein thrombosis (DVT) in the lower limbs. As a leading cause of in-hospital mortality, its management requires rapid risk stratification and adherence to standardized clinical guidelines.

: When thrombolysis is contraindicated or fails, options include catheter-directed thrombectomy or surgical embolectomy. Prognosis and Follow-Up 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.
Treatment strategies are dictated by the patient's hemodynamic stability and risk category.
