Case Report: Extensive Pulmonary Thrombectomy for Acute Massive Pulmonary Embolism

A 56-year-old male with a history of hypertension and recent knee surgery presented to the emergency department with sudden-onset dyspnea, chest pain, and syncope. Vital signs revealed tachycardia (pulse 128 bpm), hypotension (blood pressure 85/50 mmHg), and hypoxemia (SpO2 88% on room air). Physical examination showed jugular venous distension and a loud P2, suggestive of RV strain.³ Electrocardiography demonstrated sinus tachycardia, S1Q3T3 pattern, and incomplete right bundle branch block.⁵ Laboratory findings included elevated D-dimer (4500 ng/mL), troponin I (0.8 ng/mL), and brain natriuretic peptide (BNP, 650 pg/mL), consistent with acute PE and RV dysfunction.⁶,⁷
