[Renal-rachidian venous trunk. Replacement of the left renal vein. A danger for the spinal cord (author's transl)].

In two cases of paraplegia due to an inondation of the intrarachidian plexus by venous blood from the left venal vein, we studied the frequency with which the renal-rachidian trunk connected the left renal vein and the intrarachidian plexus. We show in these rare cases how it is possible, with a simple procedure, the ligature of the renal-rachidian trunk, to bring about a marked regression in the paraplegia. This procedure has been carried out five times, and it should be seen within the wider framework of a serie of procedures on the cava system, which are now practised for more than forty years.
