[Improved intraoperative leak control in cytostatic drug isolation perfusion of tumors of the extremities].

The success of extremity perfusion and the protection from systemic side effects largely depend upon the prevention of systemic drug leakage from the extremity circulation. The use of autologous 111-Indium labelled erythrocytes for leakage control allows a continuous exact surveillance and timely correction of the tourniquet position in case a major leak should occur. A total of 97 patients were studied.
