This transverse saphenous vein is immediate post R/F thermoablation and has the typical wall thickening resembling a "cheerio".  This is a good indication of intimal denuding and effective treatment.
	This is an image of an incompetent Cockett perforating vein.  Note the retrograde flow from the tibial vein into the saphenous vein with augmentation. Perforators > 3mm in diameter are associated with reflux in >90% of the cases.
	This image is 1 month post (RFA) RadioFrequency Ablation of the greater saphenous vein (GSV) due to severe incompetence.  The image is at the saphenofemoral junction.  Note the patent common femoral and femoral vein with inflow from the superior epigastric vein. The GSV is closed as expected.
	Image of laser fiber extending out of sheath during EVLT (EndoVenous Laser Treatment).  The fiber pertrudes approximately 2 cm out of the sheath during laser ablation of the saphenous vein and the sheath and laser are removed together during treatment, sealing the vein.
	Image of a greater saphenous vein anterior wall aneurysm.  This saphenous vein had obvious severe incompetence and contributed to significant distal varicosities.
