Guideline No.	GRADE of recommendation	Level of evidence
10.1	2	B
For treatment of the incompetent great saphenous vein, we suggest high ligation and inversion stripping of the saphenous vein to the level of the knee.

To reduce hematoma formation, pain, and swelling, we recommend postoperative compression. The recommended period of compression in C2 patients is 1 week.

10.3	1	B
For treatment of small saphenous vein incompetence, we recommend high ligation of the vein at the knee crease, about 3 to 5 cm distal to the saphenopopliteal junction, with selective invagination stripping of the incompetent portion of the vein.

To decrease recurrence of venous ulcers, we recommend ablation of the incompetent superficial veins in addition to compression therapy.

We suggest preservation of the saphenous vein using the ambulatory conservative hemodynamic treatment of varicose veins (CHIVA) technique only selectively in patients with varicose veins, when performed by trained venous interventionists.
Guideline No.	GRADE of recommendation	Level of evidence
10.6	2	C
We suggest preservation of the saphenous vein using the ambulatory selective varicose vein ablation under local anesthesia (ASVAL) procedure only selectively in patients with varicose veins.

10.7	1	B
We recommend ambulatory phlebectomy for treatment of varicose veins, performed with saphenous vein ablation, either during the same procedure or at a later stage. If general anesthesia is required for phlebectomy, we suggest concomitant saphenous ablation.

10.8	2	C
We suggest transilluminated powered phlebectomy using lower oscillation speeds and extended tumescence as an alternative to traditional phlebectomy for extensive varicose veins.
Guideline No.	GRADE of recommendation	Level of evidence
10.9	2	C
For treatment of recurrent varicose veins, we suggest ligation of the saphenous stump, ambulatory phlebectomy, sclerotherapy, or endovenous thermal ablation, depending on the etiology, source, location, and extent of varicosity.
