Pulmonary Thromboembolectomy Surgery is a specialized procedure performed to remove blood clots blocking the pulmonary arteries in the lungs. These clots can severely affect oxygen supply and place dangerous strain on the heart and lungs. The surgery is commonly recommended for acute or chronic pulmonary thromboembolism when medications alone are not effective. Using advanced cardiothoracic surgical techniques, detailed imaging, and specialized critical care support, blocked pulmonary arteries are cleared to restore healthy blood circulation and breathing function. Early treatment is important to prevent life-threatening complications such as pulmonary hypertension and heart failure.
