OBJECTIVE

To compare the morphological features of damage to great saphenous vein (GSV) after endovenous laser ablation (EVLA) with 1940 and 1560 nm laser.

MATERIAL AND METHODS

A multiple-center prospective study was carried out. We assessed GSV wall specimens after EVLA with 1940 nm laser and power of 4, 5, 6, 7, 8 W and 1560 nm laser with power of 5, 6, 7, 8, 9 W in vitro. Optic fiber traction speed was 1 mm/s in both groups. Saphenous veins were obtained after crossectomy and stripping (mean vein diameter 9.3±2.7 and 9.9±2.8 mm, respectively).

RESULTS

EVLA with 1560 nm laser causes damage to the entire GSV wall up to adventitia, medium and large foci of vaporization and loss of internal structure at 8—9 W (linear energy density 80—90 J/cm). In case of 1940 nm laser, damage to the entire GSV wall up to adventitia, medium and large foci of vaporization and loss of internal structure occur at 5—6 W (linear energy density 50—60 J/cm).

CONCLUSION

In EVLA with 1940 nm laser, damage to the entire GSV wall with loss of internal structure up to adventitia occurs in less energy exposure compared to 1560 nm laser.
