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. It can be used to relieve a blockage in the bile duct, either permanently or as a temporary solution before definite treatment such as surgery.
The most common drainage sites are the right ventricle in around 40% cases, right atrium in 26% cases, pulmonary artery in 17%, coronary sinus in 7%, left ventricle in 3% and the superior vena cava in 1% cases. 2 Circumflex to SVC fistula has been reported very rarely, first time in 1966.
