[Intraoperative pulmonary embolism of a hydatid membrane]

Only four cases of per-operative pulmonary embolus of parasites during surgery for hydatic cysts of the liver have been reported. Embolus usually occurs in patients who already have lung metastasis of hepatic cysts, suggesting a hepatic cyst in direct communication with the vena cava or suprahepatic vein. We report the first case which occurred in a patient in which there was no evidence of such communication.
