the brilliant study

Conditions: Varicose Veins

Summary: this trial was designed as a prospective, multi-center, randomized clinical trial of the fda-cleared vari-lase bright tip fiber compared to commercially available standard bare-tip laser fiber (control) to demonstrate the safety and effectiveness of laser ablation for the treatment of varicose veins associated with reflux within the great saphenous vein (gsv) and to provide additional data concerning patient satisfaction. within this evaluation, subject limbs were randomized to one of two (2) treatment groups utilizing a 1:1 randomization ratio. if a subject required treatment of only one limb, that limb was randomized to a treatment group. if a subject required treatment of two limbs, the first limb was randomly assigned treatment and the second limb was assigned the other treatment (the opposite treatment of the other limb). the data was analyzed by treated limb (versus treated subject).all study data were analyzed under the principles of intent-to-treat, in which data are analyzed according to the assigned randomized group regardless of the treatment actually delivered. subjects were followed at one week, one month, and six months.

this trial was designed as a prospective, multi-center, randomized clinical trial of the fda-cleared vari-lase bright tip fiber compared to commercially available standard bare-tip laser fiber (control) to demonstrate the safety and effectiveness of laser ablation for the treatment of varicose veins associated with reflux within the great saphenous vein (gsv) and to provide additional data concerning patient satisfaction. subjects were pre-screened utilizing standard of care data (including documented evidence of reflux within the gsv) for the specified inclusion/exclusion criteria to ensure that they were eligible for treatment in the investigation. prior to laser treatment and after signing an informed consent form, study eligibility assessments were completed including physical assessment of target limb(s), duplex ultrasound of gsv segment(s) targeted for treatment, symptom assessment, medical history, and digital photos of targeted limbs. upon enrollment, targeted limbs were randomized at a 1:1 ratio to receive the vari-lase bright tip fiber or the control treatment. if the subject required treatment of two limbs, the first limb was randomized and the second limb was assigned the other treatment (the opposite treatment of the other limb). immediately post procedure, subjects were assessed for adverse events and a physical assessment of the treated limb(s) was performed. subjects were also asked to complete a subject pain and satisfaction questionnaire. subjects were followed at one week, one month, and six months. follow-up included a physical assessment of treated limb(s), symptom assessment, adverse event assessment, and completion of a subject pain and satisfaction questionnaire. additionally, a duplex ultrasound assessment was conducted at one week and six months and digital photos were taken of the treated vein segment(s) at one week and one month. the data was analyzed by treated limb (versus treated subject). all study data were analyzed under the principles of intent-to-treat, in which data are analyzed according to the assigned randomized group regardless of the treatment actually delivered.

Eligibility criteria:
inclusion criteria: 1. subject is 18 years of age or older 2. subjects with primary varicose veins resultant of gsv reflux documented on duplex ultrasound 3. subjects that will be undergoing endovenous laser ablation treatment of varicose veins 4. subjects treatment includes the greater saphenous vein 5. if bilateral, subject is willing and able to undergo treatment of both legs within two weeks. 6. subjects who are willing and able to comply with the requirements of the study protocol 7. subjects who are willing and able to provide informed consent exclusion criteria: 1. subjects with severe peripheral vascular disease (pvd) as evidenced by an ankle-brachial index of \< 0.5 2. subjects who are unable to ambulate at baseline 3. subjects with thrombosis in the vein segment(s) to be treated 4. subjects that have had prior vein treatment 5. subjects who are known or suspected to be pregnant or lactating 6. subjects that are concurrently participating in an investigational study that may confound the treatment or outcomes of the present study 7. subjects with an active or systemic infection 8. anatomic variants- duplication of the gsv, presence of incompetent accessory veins of the gsv 9. subjects who are scheduled to have a bilateral treatment, where one limb is to be enrolled in this study and the second limb that is not treated as part of this study, is treated within two months of the procedure for this study
