Rapport de patient au Canada. C'est très spécifique donc je ne trouve pas dans mon dico Dorland.

Sort of doesn't help that watershed necrosis can affect many parts of the body and that it's painful to think about or research!
I will keep searching and see what I come across.

nécrose d'une zone jonctionnelle (en raison d'une hypoperfusion)
Explanation:

IN ENGLISH:
https://en.wikipedia.org/wiki/Watershed_area_(medical)
"Watershed area"
Watershed area is the medical term referring to regions of the body that receive dual blood supply from the most distal branches of two large arteries [...]

https://en.wikipedia.org/wiki/Watershed_stroke
[...] In a medical context, the term "watershed" refers to those areas of the brain that receive dual blood supply from the branching ends of two large arteries.

[...] Watershed strokes affect areas of the brain which are at risk of low blood flow during extreme drops of blood pressure.

[...] Vascular watershed or border-zone infarctions occur at the most distal areas between arterial territories.

IN FRENCH:
https://www.em-consulte.com/article/254026/les-accidents-vas...
Les accidents vasculaires cérébraux ischémiques sont dits jonctionnels lorsqu’ils surviennent à la limite entre deux territoires artériels. Ils sont dus à un bas débit, d’où une atteinte cérébrale circonscrite aux zones les plus vulnérables à l’hypoperfusion.

Bas débit (les territoires jonctionnels sont les plus fragiles en cas de baisse de débit)

https://www.carotide.com/le-polygone-de-willis/
En imagerie, IRM ou scanner cérébral, les infarctus se situent à la jonction de deux territoires vasculaires (infarctus jonctionnel).

"watershed infarct - aetiology"
...If you and friends go out for dinner to a restaurant at a table for 20 people and the waiter places 3 bottles of wine at each end then as everyone pours a glass and passes it on everyone should get a drink. If however on another night you can only afford 1 bottle at each end of the table then those in the centre will find that the bottle is empty by the time it gets there. This is the watershed area and can in the brain be a line of infarction. It only happens when there is a generalised reduction in blood flow and the areas at the edges of any territory will get the least. One cause may be global drop in BP during sepsis or other causes of shock or during surgery or an occluded or critically stenotic ICA which supplies ACA and MCA and so this is where infarction is worst. The important issue is that the cause may be significantly proximal to the infarct such as a severely stenotic carotid or systemic hypotension.

You're welcome. I didn't find it immediately either, and it seems there is no set term in French for "watershed necrosis". But this seems to work ok as an interpretation.

Asker: Nathalie thank you so much - this is exactly what my English sources have been saying, but I would never gave thought of zone jonctionnelle for border zone. Thank you!
