[Percutaneous puncture in hepatic echinococcosis].

This is a report on a case of severe anaphylactic shock and hemorrhage following liver puncture with diagnostic purpose. Based on literature data and personal experience, percutaneous puncture of a parasitic expanding cyst, done with diagnostic and therapeutic purpose, is discarded, assuming the method as an error of art. Its performing using updated imaging techniques--echography and computerized tomography--by no means reduce the risk of anaphylactic shock and secondary echinococcosis. In the event of being accidentally done, emergency operation followed by chemotherapy to preclude secondary echinococcosis is recommended. In cases with unspecified diagnosis, puncture under echographic control is done on the operating table with urgent cytological assessment of the punctate. The demonstration of echinococcosis is an indication for immediate operation. The percutaneous method is used in handling nonparasitic cysts.
