Cystic vein

Cystic Vein

The cystic vein (shown in red) drains the gallbladder into the common hepatic vein.

The cystic vein is a small blood vessel that drains blood from the gallbladder and empties into the common hepatic vein. It is a part of the portal venous system, which carries blood from the gastrointestinal tract and spleen to the liver.

Structure

The cystic vein typically arises from the neck of the gallbladder and joins the common hepatic vein. However, its course and drainage can vary. In some individuals, it may drain directly into the portal vein or the right hepatic vein.

Function

The primary function of the cystic vein is to carry deoxygenated blood away from the gallbladder. This blood is rich in nutrients absorbed from the food we eat, which are then processed in the liver.

Clinical significance

Knowledge of the cystic vein's anatomy is crucial during cholecystectomy, a surgical procedure to remove the gallbladder. Misidentification or injury to the cystic vein can lead to significant bleeding and other complications.
