Endovenous Laser Therapy (ELT) Of Saphenous Vein Reflux Using Thulium Laser (Tm, 1940 nm) with Radial Fiber – One Year Results

Abstract

rate within the first year from 30% to 10% of the patient population. A secondary objective is a non-inferiority of MonoMax suture material (group C) in comparison to MonoPlus (group A). Results: 108 patients were randomized between February 2011 and July 2013. The compare of demographic data, risk factors and co-morbidities did not reveal structural differences between the study groups. After 12 months 4.55% of the patients with an additional implanted mesh in onlay position (group B) had developed an incision hernia versus 21.74% undergoing midline closure using two monofilaments suture loops (group A). In group C 18.18% of patients with 12-months-follow-up had an incision hernia. Non-parametric binomial testing assuming a hernia rate of 20% or 30% after 12 months was performed. For group A and C, herniation significantly differing from 20% (p ¼ 0.499 respectively p ¼ 0.543) or 30% (p ¼ 0.269 respectively p ¼ 0.165) could be refused, while the number of hernias in group B significantly differed from 20% (p ¼ 0.048) and 30% (p ¼ 0.004). Wound healing disorders occurred in15.19%. Notable differences were visible in formation of seromas which were exclusively found in patients of group B (19.23%) but not in group A or C. In total, re-surgery of the abdominal wall was performed in n ¼ 11 patients (10.68%). This number also includes n ¼ 4 non-emergency interventions (revision of the abdominal wall because of persistent seroma or repair of incision hernia). Conclusion: Additional mesh in onlay position after median laparotomy for AAA can reduce hernia rate significantly.

Comparison of Short-Term Outcomes Between Endovenous 1,940-nm Laser Ablation and Radiofrequency Ablation for Incompetent Saphenous Veins

“…According to previous literatures, the required energy for good outcomes is about 80-100 LEED (J/cm) with the 1,470nm EVLA (11,13,14). And to date, a few studies have investigated EVLA using the 1,940-nm laser, and this treatment has generally produced good outcomes, even with energy < 50 LEED (J/cm) (19)(20)(21)(22)(23)(24).…”

Initial outcomes of endovenous laser ablation with 1940 nm diode laser in the treatment of incompetent saphenous veins

“…[10][11][12][13] However, there are few studies on the effective power or LEED at a longer wavelength of 1940 nm, and all have focused on radial fibers. 6,[14][15][16] In addition, no studies have specifically investigated the Asian population.…”

“…To assess the outcomes of EVLA with long wavelengths (1320–1940 nm) and modified probes, randomised controlled studies [ 384 , 385 , 416 , 417 , 420 , 426 , 427 , 430 , 431 ], prospective comparative studies [ 415 , 418 , 419 , 422 , 425 ], retrospective comparative studies [ 429 , 433 ], and prospective cohort studies [ 382 , 421 , 424 , 428 , 434 ] are available. The long-term outcomes up to 5 years are reported.…”
