Complication rate with the 1940-nm versus 1470-nm wavelength laser.

Background: We hypothesized, that endovenous laser ablation (EVLA) with the highly water specific 1940-nm wavelength laser would reduce ablation-related thrombus extension (ARTE) incidence compared to the less specific 1470-nm laser.

Materials And Methods: Between February 2017 to March 2023 we identified a consecutive series of patients undergoing EVLA from the prospectively ongoing VEINOVA registry. Patients were treated with the 1940-nm or 1470-nm laser.

Endovenous Thermal Ablation for Treatment of Symptomatic Saphenous Veins-Does the Body Weight Matter?

Objective: This study aimed to examine whether body weight may affect the effectiveness and safety of endovenous thermal ablation (ETA) for the treatment of symptomatic varicose veins.

Methods: This retrospective single-center cohort study analyzed the outcomes and patient demographic data with a focus on the body weight of all patients who had ETA of symptomatic varicose veins between September 2017 and October 2020.

Results: A total of 1178 treated truncal veins from 636 patients were analyzed.

Venous thrombosis following endovenous laser ablation with and without thromboprophylaxis.

Objective: Venous thromboembolism (VTE) occurs infrequently after endovenous laser ablation (EVLA). The purpose of this study was to assess the incidence of VTE after EVLA with and without pharmacologic prophylaxis.

Methods: From October 2019 to March 2020, a series of consecutive patients from the prospectively maintained VEINOVA (vein occlusion with various techniques) registry was retrospectively analyzed.

Safety, feasibility, and early efficacy of the water-specific 1940-nm laser wavelength for ablation of saphenous incompetence.

Objective: The aim of the present study was to evaluate the safety, feasibility, and early efficacy of saphenous vein ablation using a water-specific 1940-nm diode laser wavelength using low linear endovenous energy density.

Methods: We retrospectively analyzed a series of patients who had undergone endovenous laser ablation (EVLA) between July 2020 and October 2021 from the multicenter, prospectively maintained VEINOVA (vein occlusion with various techniques) registry. EVLA was performed using a water-specific 1940-nm radial laser fiber.

Safety and efficacy of endovenous thermal ablation for treatment of symptomatic varicose veins during summertime.

Traditionally, varicose vein treatment is predominately performed during the colder seasons. However, data whether higher outdoor temperatures affect the outcome and/or complication rate of endovenous thermal ablation (ETA) for treatment of symptomatic varicose veins are missing. In this observational study, the medical records of all patients who had ETA of the great saphenous vein (GSV), accessory saphenous vein (ASV), or small saphenous vein (SSV) between September 2017 and October 2020 were reviewed.

Combining Proximal Foam Sclerotherapy and Distal Endovenous Laser Ablation for Recurrent Varicose Vein Treatment.

Background: Recurrent varicose veins with neovascularization are a common clinical problem. Although endovenous laser ablation (EVLA) has become the standard treatment modality to treat truncal veins, additional sclerotherapy is required to treat newly formed tortuous veins. A novel laser fiber with an injection channel (nLF) allows for such simultaneous proximal sclerotherapy and offers a potentially more effective treatment option.

Feasibility and safety of flush endovenous laser ablation of the great saphenous vein up to the saphenofemoral junction.

Objective: The optimal ablation distance from the catheter tip to the common femoral vein during endovenous laser ablation (EVLA) of the great saphenous vein (GSV) is a matter of debate. In this study, we evaluated the feasibility and safety of flush ablation (fEVLA) of the GSV.

Methods: This single-center, retrospective analysis of prospectively collected data included all consecutive fEVLA interventions of the GSV between September 2017 and October 2018.

Perforator vein endovenous heat induced thrombosis after laser ablation of the great saphenous vein.

Endovenous heat induced thrombosis at the sapheno-femoral or sapheno-popliteal junction is a well-known complication after superficial truncal vein endovenous laser ablation (EVLA). This report describes a rare thigh perforator vein thrombus propagation into the femoral vein after EVLA of the great saphenous vein.

Bedside hand vein inspection for noninvasive central venous pressure assessment.

Rapid estimates of the central venous pressure (CVP) can be helpful to administer early fluid therapy or to manage cardiac preload in intensive care units, operating rooms or emergency rooms in order to start and monitor an adequate medical therapy. Invasive CVP measurements have inherent and non-negligible complication rates as well as great expenditures. Several noninvasive methods of CVP measurements, like ultrasound-guided techniques, are available, but require trained skills and special equipment which might not be at hand in all situations.

Rivaroxaban for thrombosis prophylaxis in endovenous laser ablation with and without phlebectomy.

Objective: Endovenous heat-induced thrombosis (EHIT) is a well-described complication of endovenous laser ablation (EVLA). We report our centers' experience on the efficacy (EHIT level ≥2 according to the Kabnick classification) and safety (observed major and minor bleeding events) of rivaroxaban for EHIT prophylaxis in EVLA with and without concomitant phlebectomy.

Methods: Demographic, procedural, and outcome data of all patients with EVLA of the great, accessory, or small saphenous vein and EHIT prophylaxis with 10 mg/d rivaroxaban between 2012 and 2014 were reviewed and analyzed in this investigator-initiated multicenter retrospective observational single-arm study.
