I forgot the medical term but when you have a REALLY bad liver the blood starts to take other ways to the heart to circumvent it (kollateral paths).
One path is going through your oesophagus so your venes widen very much. With the widening the risk of a rupture starts to increase very much and as soon as it does, there is nothing much that can save you.
I am not saying he got that but the description fits very much on point.

As you can see, fairphone still sells spare parts for the fairphone 2, that came out years ago (i think ~8?). So as long as fairphone isnt going bankrupt you have a good chance to get any spare part you need for years to come.
