Right branch
Ramus dexter
- Related terms: Right branch of hepatic portal vein
Definition
The portal vein divides into a right branch and a left branch just before or at the level of the porta hepatis.
The right branch arises as a robust, relatively short trunk, coursing laterally and dorsocranially toward the right hepatic lobe. In some species, such as the horse and dog, this branch also gives off subdivisions that supply the quadrate and sometimes the caudate process of the caudate lobe, or like in the cats, there may be separate right lobar portal vein draining the caudate process of caudate lobe.
