[Study of anastomoses between the left renal vein and the internal vertebral plexus].
Anastomosis between the left renal vein and the rachidian plexus exists in about 80% of the cases (16 cases out of 20); they are important in 25% of the cases (5 cases) ; their origin is constant ; their ending has a high frequency for the rachidian plexus of the intervertebral foramen L1-L2. These anastomoses are of great importance : as they are the only renal circulation's safety device in seven of our cases : their hypertrophy in some pathological cases can explain some neurological clinical pictures of compression, reversible after the ligature of the hypertrophic anastomotic veins.
