ClariVein ® OC can alleviate varicose veins, compared with radiofrequency ablation lighter pain, quality of life

Varicose veins is a common disease worldwide.Current estimates affects as many as three over ten of the adult,1Varicose veins to cause a decline in the quality of life significantly, resulting in health care costs increase.2

For treatment of varicose veins, veins and internal melting is considered the gold standard of treatment, but the technology is not without patient discomfort.In recent years, in order to improve the treatment of patients with varicose veins experience, have developed and implemented a new therapy.

A multicenter, randomized controlled trial2Northwest at imperial college London and London hospitals NHS trust fund, the researchers found with radiofrequency ablation (an internal vein ablation) compared to the use of minimally invasive smaller ClariVein OC to treat pain, and produce a similar short-term results and quality of life and safety.

The research,2Published inVein to learnAnd randomly assigned them, recruited 170 patients treated with radiofrequency ablation or use ClariVein OC.The researchers during treatment using visual analog scale (VAS) and digital scale (0 to 10) check pain score.And XNUMX XNUMX months months of follow-up, in patients with leg after treatment for clinical grading, quality of life score and ultrasonic evaluation.

results2Show that ClariVein OC group of patients during surgery by VAS (median ClariVein OC 15 mm 7-36 mm] [IQR are much less and radiofrequency ablation [IQR are much less 16-53 mm] 34 mm, p = 0.003) and digital scale (median ClariVein OC 3 [IQR are much less 1-5) and radiofrequency ablation (IQR are much less 3-6.5), 4 p = 0.002).

data2Also showed that ClariVein OC group average pain score significantly lower (VAS a median of 10 mm / 3-25 mm vs. 19.5 mm [9] - 38 mm, p = 0.003, the Mann - Whitney, digital scale median 0.5 4], [2 to 3 [2-5], p = 0.004, Mann Whitney).

In XNUMX and XNUMX months, between groups of occlusion rate, clinical severity score, similar disease specificity and general quality of life scores.2In general, patients in the recovery work in two days and normal activity (IQR are much less 2-7 and 1-6), respectively.Adverse events include two deep vein thrombosis, one in each group.

The researchers concluded2With similar technology, short term life, compared to the results of quality and safety of radiofrequency ablation used ClariVein OC less pain for the treatment of varicose veins.Clinical outcome and recovery time were similar in the work and normal activities.These findings support comparison between ClariVein OC and radiofrequency ablation of pain in patients with other data3And publishedFollow-up data for five yearsCheck the long-term efficacy of ClariVein OC.4

Varicose veins can be very ugly, and causes discomfort for some patients.Varicose veins is the root cause of venous reflux disease, when the valves of the intravenous weaken or damage will occur this kind of disease.When this happens, blood will flow back and gathered in intravenous, cause vein expanded.Varicose veins is the most common in the legs and feet.If not treated, venous reflux disease will develop into other, more serious circulation and skin problems.

For treatment of varicose veins, radiofrequency ablation using imaging guide will be a small catheter guided vein in order to transfer heat to the pathological changes, resulting in blood vessel walls collapse and shut down.Although is considered to be effective, radiofrequency ablation need to use involves swelling anesthesia needle injection.

ClariVein OC will be professional, by contrast, the function of the infusion catheter combined with rotating wire tip, designed for the target vessels designed control 360 degrees within the doctor prescription drugs.ClariVein OC just skin to enter the size of needle and treatment time is very short, do not use heating or swelling anesthesia, and minimize the effects of stress on the patients.
