| Name = Transverse fissure of liver | Latin = porta hepatis | Image = Gray1086-liver.PNG | Caption = Inferior surface of the liver. | Image2 = Gray591.png | Caption2 = The portal vein and its tributaries. (Porta hepatis labeled at upper left.) | System = | Precursor = }} The porta hepatis or transverse fissure of the liver is a short but deep fissure, about 5 cm long, extending transversely beneath the left portion of the right lobe of the liver, nearer its posterior surface than its anterior border. It joins nearly at right angles with the left sagittal fossa, and separates the quadrate lobe in front from the caudate lobe and process behind. FunctionIt transmits the following (in anterior to posterior order):
The hepatic duct lies in front and to the right, the hepatic artery to the left, and the portal vein behind and between the duct and artery. It also transmits nerves and lymphatics.
LocationWhen the patient is supine, and the liver observed inferiorly (as in a surgeon's perspective), the important structures demarcating its inferior aspect can be represented by a hepatic "H" figure. The right vertical limb of the "H" defines the left and right functional lobes, while the left vertical limb of the "H" defines the right and left anatomical lobes. The horizontal line between the vertical limbs of the "H" represents the porta hepatis. The quadrate and caudate lobe lie superior and inferior to this line respectively. See also
