[Substernal goiter: pre-, intra- and postoperative problems].

The Authors report their experience with problems in treating substernal goiter. They then explain at length the complex haemodynamic or respiratory situations encountered and the therapeutic management of the condition. Also discussed are technical surgical problems, and the prevention and therapy of possible complications. They conclude by stating that thanks to all the technical means currently available complete patient control can be achieved before, during and after the operation, thus significantly contributing to the successful outcome of surgical treatment.
