title: Massive pulmonary embolism during orthopedic surgery.
abstract: A 90-year-old female patient undergoing surgery for knee and hip fractures under general anesthesia sustained cardiac arrest intraoperatively. The transesophageal echocardiography performed during resuscitation revealed massive pulmonary embolism with a 2 x 3 cm oval-shaped thrombus in the bifurcation of pulmonary artery. Anticoagulant therapy was administered immediately. Clinical symptoms were gradually improved, and transthoracic echocardiography performed 5 days later revealed no evidence of residual thromboemboli. Subsequently the patient developed liver and acute renal failures in consequence of hypoperfusion during the intraoperative resuscitation, and died of multiple organ failure 21 days after the procedure. We conclude that transesophageal echocardiography is a useful diagnostic instrument and should be utilized in high risk patient as early as possible, even before and during surgery.
