Unexpected complication of massive intraoperative pulmonary embolism following elective sigmoidectomy in the supine position.
We describe a case of massive intraoperative pulmonary thromboembolism during elective sigmoidectomy in the supine position. During recovery from anesthesia, the patient developed hemodynamic compromise and severe hypoxemia. Intravenous inotropes and mechanical ventilation were instituted. The abrupt onset of symptoms and the pulmonary artery catheter, chest radiograph, and transesophageal echocardiography findings suggested massive pulmonary thromboembolism as a possible cause of the hemodynamic compromise and hypoxemia. Emergent angiography could not be carried out due to the patient's poor clinical status. Lack of experience in performing embolectomy, along with contraindication for thrombolysis, imposed the use of intravenous heparin and hemodynamic support as the only appropriate therapeutic modality. After 2 days' aggressive hemodynamic and ventilatory support, the patient had an uneventful course, and was discharged from the intensive care unit (ICU) 14 days later.
