Surgical removal of a clot is called an embolectomy. This type of treatment for pulmonary embolism is rarely used. It is considered when the clot in the main pulmonary artery is extremely large and life-threatening and is causing severe symptoms.
Home treatment is not recommended for initial treatment for pulmonary embolism. However, it is important for preventing additional clots from developing and causing a deep vein thrombosis, which can lead to recurring pulmonary embolism.
