[Partial disarterialization of the spleen and partial splenectomy in children]

Splenic hyperactivity can be reduced by partial vascular disconnection of the spleen or by partial splenectomy. The first method, which preserves only one superior polar artery and the whole venous system, was used in 6 patients, and the second method, which preserves a small portion of the spleen, usually fed by an inferior polar artery, was used in 11 patients. Ultrasonographic and scintigraphic measurements of the spleen, platelet counts, transfusion quotient and 51 Cr-labelled red cell survival were used to evaluate the effects of these two methods. No immediate post-operative complication was observed.
