[Value and limitations of venous blocks using reserpine in acrosyndromes of the upper extremities]. / Intérêt et limites du bloc veineux à la réserpine dans les acrosyndromes du membre supérieur.

ABSTRACT

A block Bier technique using a one milligram Reserpine injection has been applied to ten patients with severe Raynaud's phenomenon (six of them had digital gangrene). Six patients have been improved and three have completely healed. This method must only be applied to severe cases and may be used as a pretherapeutic test in upper sympathectomy.
