ABSTRACT
AIM: To evalue the short-term results obtained in endovenous laser ablation (EVLA) procedure of the varicose insufficiency of the lower limbs with Diode 1470 μm laser compared to Diode 1940 μm laser.
MATERIALS OF STUDY: A total of 55 patients were enrolled in the study. The patients were divided into two groups: those subjected to 1470 μm laser treatment in group A and those with 1940 μm laser treatment in group B. The endpoints were: Closure of the target vessel, complications and post-operative pain.
RESULTS: There are no intra-and post-operative complications. The occlusion rate of the target veins was 100% at 7- and 60-day controls. The pain perceived in the immediate post-operative and at the controls showed no statistically significant differences between the two groups. However in group B it was necessary to apply lower values of Power (W) and Linear Energy Density (LEED) with a statistically significant difference compared to group A.
DISCUSSION: Short-term results demonstrate closure rates comparable to those obtained with 1470 μm lasers. There were no statistically significant differences in the two groups in terms of primary and secondary endpoints. The advantage of using 1940 μm laser technology is that it is possible to dispense a lower linear energy density (LEED) at a lower power (Watt).
CONCLUSIONS: Endovenous laser ablation with Diode 1940 μm is particularly suitable and advantageous in the treatment of superficial and small vessels, as well as venous segment adjacent to nerve structures.
