Hope someone can help with this. Patient has steal syndrome from AV fistula. Doc makes incision over fistula, then places three separate sutures as imbricating sutures just above the level of the anastomosis to narrow the vein at that point. Is this revision or ligating?
Thanks for any and all help.

Av fistula

I would say this is ligating as ligation is a narrowing of athe vessel - that would be my opinion
