[Retroperitoneal extravasation -- rare complication with parenteral nutrition (author's transl)].

Hydrothorax and retroperitoneal extravasation are rare complications with parenteral nutrition. We demonstrate here a case of perforation of the iliac vein with retroperitoneal extravasation, which led to laparotomy because of signs of peritonitis. Catherization of peripheral and central veins and the complications arising are discussed.
