[Evaluation of experimental arterial occlusion, with special reference to its complications (micro-spheres, Histo-Acryl, Paladur, alternating and direct currents (author's transl)].
Permanent arterial occlusion can be obtained experimentally by using plastic micro-spheres, polymerising materials (Histo-Acryl, Paladur) and direct current thrombosis. Certain limitations in their use arise from the properties of the substances. In our experience, plastic microspheres are not suitable for blocking entire organs or large vascular territories. They are more appropriate for occlusion of individual, small vessels by super-selective injections. Sole use of polymerising materials is not possible; they are best used in combination with other techniques (magnets, balloon catheters). Induction of thrombosis by small direct currents (50 volt, 10 mA). produces permanent and complete occlusion. The method can be used selectively or super-selectively. Unwanted thrombosis can be avoided by using catheters with the smallest possible external diameters.
