[Formation of a large blister with subsequent necrosis of the skin following paravenous contrast medium injection at the dorsum of the foot in a patient with oedema and deep phlebothrombosis (author's transl)].

In a female patient with an oedema of the leg as a result of deep phlebothrombosis, a great blister developed at the dorsum of the foot proximal to the site of injection following phlebography effected by paravasal contrast medium injection. The blister was transparent and contained clear, serous liquid. Skin necrosis developed at this site which took months to heal. The reason is sought in a stasis of contrast medium caused by the oedema. It is suggested that in future cases of this kind, cortisone treatment should be attempted.
