[Algodystrophy and venous thrombosis of the lower extremities. Diagnostic discussion. Apropos of 3 cases].

The authors report 2 cases of probable algodystrophy of the lower extremities, associated to a definite deep venous thrombosis. They discuss the relationships between the two diseases and the difficulties of the differential diagnosis in light of a third case where the algodystrophy is definite and manifests itself as a deep venous thrombosis confirmed by phlebography. They insist on the absolute need to rule out a deep venous thrombosis before considering the exceptional diagnosis of algodystrophy with pseudo-phlebitic manifestations.
