[Neuromuscular and phlebothrombotic clinical aspects of primary magnesium deficiency]

The symptomatology of the neuromuscular hyperexcitability due to magnesium deficit is non-specific. An analysis of its diagnostic criteria and of the etiological and physiopathological problems is made. The description of a phlebothrombosis syndrome due to primary magnesium deficit must lead to an investigation of the part played by this ionic disturbance in various thrombogenic conditions which may induce a leakage of this ion. Practical data related to the problems raised by the administration of oral magnesium therapy.
