BACKGROUND Endovenous laser ablation (EVLA) was performed in the treatment of great and small saphenous veins (GSVs, SSVs), perforating veins (PVs), and varicose collaterals (VCs). OBJECTIVE To verify the outcome in PVs and VCs. MATERIALS AND METHODS Four hundred eighty-two limbs of 306 patients were studied. EVLA was performed on 167 GSVs, 52 SSVs, and 534 PVs of 303 limbs and on VCs of 467 limbs; 133 GSVs were stripped, 300 of saphenofemoral junctions (SFJs) and 45 saphenopopliteal junctions (SPJs) were interrupted. Limbs were selected using duplex ultrasound examination and photographs; PVs-VCs diameter (<4 mm) and VC length were measured. EVLA was performed using a 808-nm diode laser, 0.6-mm fibers, continuous emission, 4 to 10 W, and 10 to 20 J/cm. Follow-up on 467 limbs occurred over a mean 27.5 months (range 3 months to 6 years); 98 limbs were followed up for longer than 4 years. RESULTS Operating time range from 10 to 30 minutes per limb. Blood vaporization, thrombosis, fibrosis, and atrophy prevailed in PVs and in the large VCs (>4 mm) and massive coagulation in the smaller (<4 mm). High rate of occlusion was seen, with different rates of patent PV-VC mainly in diameter >6 mm. Thirty-nine out of 511 patent PVs (7.6%) and 96 out of 778 VCs (12-13%) were re-treated using EVLA or foam sclerotherapy. Minor complications occurred in 88 of the 778 (11%). CONCLUSIONS EVLA of PVs and VCs is effective and faster than surgery in 2- to 6-mm PVs and VCs using an 808-nm diode laser. This study was supported by Eufoton, Trieste, Italy.
