Successful emergency pulmonary embolectomy with the cardiopulmonary bypass was performed in a 41 ulcorneryear old male who suffered massive pulmonary embolism after longterm bed rest due to the injury of left knee. Temporary cardiopulmonary bypass provided 120 minutes of circulatory support while complete removal of bilateral pulmonary emboli accomplished using Forgarty catheter and Gall stone forceps. Also, manual compression of the lungs was necessary to remove distal branching emboli. The patient had smooth and uneventful hospital course without complications and discharged from hospital taking coumadine on the 13th day after the operation.
