cystic artery

A gallbladder ulcer erodes into the cystic artery and is very rare. This leads to upper gastro-intestinal. This is caused due to the erosion of cystic artery.

At one point during the procedure, the cystic artery was avulsed, resulting in a fair amount of blood loss.

The arterial supply of the gallbladder is from the cystic artery which is a branch of the right hepatic artery.

Assuming that each parent is a carrier for cystic fibrosis (has the genotype Ff), the probability that their second child will develop cystic fibrosis is one fourth.

The probability doesn't change with the number of children they have. For each pregnancy, the chance that the child will have cystic fibrosis (have the genotype ff) is exactly the same.
