Case report: Novel leg vein treatment CLaCS guided by augmented reality 11 years follow‐up

Abstract

Telangiectasias is most prevalent on the lower limbs and has been estimated to manifest in 40%–90% of the population. Treatments for telangiectasias include sclerotherapy, laser therapy, intense pulsed light treatment, microphlebectomy, and thermocoagulation. Cryo‐Laser & Cryo‐Sclerotherapy (CLaCS) effectively combines thermal and injection sclerotherapy. In this treatment, unwanted veins are targeted by a transdermal laser and immediately receive injection sclerotherapy. During the whole procedure, an air‐cooling device (Cryo) blows onto the surrounding skin and tissue to prevent skin burn. Here, we present a case report of a challenging telangiectasias treated with ClaCS.

Treatment of varicose veins using the Cryo laser after foam technique

“…Previous studies have demonstrated the success of combining transdermal laser treatment with the use of sclerosants in the treatment of lower extremity varicose veins. 5 , 6 , 7 , 8 Dinache et al 10 (2020) demonstrated that the laser can interact with the foam, further reducing its microbubbles and increasing its stability, as well as allowing better interface interaction with the tissue. Additionally, external cooling provided by cold air prevented damage to the skin surface.…”

“…This technique is based on that used by Moreno-Moraga et al; however, we only use the 6-mm spot size to treat all venous calibers as proposed by Miyake et al. 5 Furthermore, we use higher and more constant energy.…”

“…Combined treatments with laser and hypertonic glucose sclerotherapy has been described with excellent results, but limited to treatment of veins <2.5 mm in diameter. 5 , 6 Laser after foam (CLaF) sclerotherapy combines the synergy of transdermal Nd:YAG 1064 laser and foam sclerotherapy with polidocanol that we modified to treat larger veins, obtaining better aesthetic results with fewer complications.…”
