Why use phlebectomy for very twisted veins?

This question asks the desk to explain a choice. Why would a very twisted vein point toward one procedure over another? One published passage speaks to it directly.

The directive: expect phlebectomy to be raised for twisted veins

www.veindirectory.org says very twisted varicose veins are often treated with ambulatory phlebectomy, not endovenous thermal ablation. The reason it gives is the catheter, which is hard to place when the vein twists a lot.

The passage behind it

The page on phlebectomy at www.veindirectory.org says:

Varicose veins that are very twisted are often treated with ambulatory phlebectomy rather than endovenous thermal ablation . This is because endovenous procedures involve inserting a small tube (catheter) into the vein, which is difficult to do when the vein twists a lot.

The source says "often", so this is a common pattern and not a rule. It ties the choice to the catheter. It does not say how twisted is too twisted, and it does not rank the two procedures for any one person.

Confirm one thing at your visit

Ask your treating clinician whether the shape of your veins affects which procedure they would suggest. For wider background, see a radiology society's guide to varicose veins, its page on endovenous varicose vein treatment and Cleveland Clinic's overview of varicose veins.

A note from the desk

The word "often" is the edge of this guidance. A vein that is twisted does not settle the matter on its own. In Westerville or elsewhere, the person who has examined your legs is the one who can say.
