Biliary drainage is performed with a tube or catheter (called a biliary drain, biliary stent or biliary catheter) by a surgeon or, commonly, an interventional radiologist.

Lateral and posterior mesencephalic veins drain the upper pons and the midbrain to the great cerebral vein of Galen, which drains to the confluence of sinuses by way of the straight sinus.
