Phlebography in crural hematoma. Differential diagnosis from recent deep vein thrombosis.

Fifteen cases of crural hematoma in which phlebography had been performed were revised. A phlebography was often normal in an early stage of hematoma. In major crural hematoma compression, displacement and occlusion of the deep venous system occurred. Non-filling of deep veins occurred in 6 cases, and venous thrombosis should therefore only be diagnosed on the basis of constant filling defects.
