[Study of anastomoses between the left renal vein and the internal vertebral plexus]
Abstract:
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.

Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

Blood and Nerve Supply to the Kidney
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of each...
