[Acute massive pulmonary thromboembolism treated with percutaneous cardiopulmonary support perioperatively].

A 57-year-old female was transferred to our hospital because of sudden dyspnea. She was hypotensive and hypoxic. Acute massive pulmonary thromboembolism was detected by echocardiography and computed tomography (CT). Before the operation, she fell into severe shock and needed cardiopulmonary resuscitation. We applied percutaneous cardiopulmonary support (PCPS), and performed emergency open embolectomy under total cardiopulmonary bypass. Because of the right ventricular failure, she could not be weaned from total cardiopulmonary bypass. PCPS was required again and used continuously during postoperative management. Her cardiopulmonary state improved gradually. PCPS was stopped at 6 days after surgery, and she was extubated at 14 days after surgery. PCPS was very useful for resuscitation and stabilization of the cardiopulmonary function for acute massive pulmonary thromboembolism perioperatively.
