Which advantages does endovenous ablation offer?

Curious what endovenous ablation has going for it, but no medical background to lean on? The list is shorter and simpler than most first-timers expect. This page is for readers in Frankfort Township.
The advantages, in plain words
my.clevelandclinic.org describes endovenous thermal ablation this way. Endovenous thermal ablation seals off varicose veins but doesn’t remove them. This means you’ll have a faster recovery time and a lower risk of complications.
So the two advantages named there are a faster recovery time and a lower risk of complications. Both are tied to the vein being sealed off instead of removed.
Two pages to open before you ask
Two publishers cover the wider topic. For one, the Society of Interventional Radiology has a patient page on superficial venous disease and chronic venous insufficiency. MedlinePlus keeps an overview of varicose veins and spider veins.
One simple next step
Open the MedlinePlus page first and jot down any term that is new to you. Then bring those terms to your own clinician and ask what a faster recovery would look like for you.
Good questions are the cheapest tool you have, and they need no special setup.
