Case Report of 195 Patients Classified by Duplex Scanning and Augmented Reality, and treated by Cryo-Laser &Cryo-Sclerotherapy (CLaCS): Results and Complications Kasuo Miyake, MD, PhD Abstract No 914 kasuomiyake facebook.com/kasuomiyake email: kasuomiyake@gmail.com Objectives / Purpose Statement: Duplex Scanning (DS) and Augmented Reality (AR) (projection of infra-red image of veins onto the skin) are new semiotic tools to a phlebology clinic. Transdermal laser is now capable of selective photothermolisis and the synergy with Dextrose75% sclerotherapy allows a more effectiveness1. This technique was designed to be free complications such as skin ulcers2, anaphylaxis and embolism. Objective: Q1- calculate the prevalence of saphenous vein insufficiency in the population evaluated Q2- evaluate treatment outcome Q3- evaluate complications -20ºC air cooling Method: Case report of 195 patients consecutive patients in a private phlebology clinic focused on aesthetic result. Conducted between August 2011 and June 2012. Examination: All patients were evaluated/treated by the author following the sequence: history, examination, duplex scanning, photo-pletismography, augmented reality, photo documentation (25 to 50 photos every session/consultation). Photos 1, 2, 3 and 4 (method): CLaCS session: AR guidance -> trans-dermal laser shots -> Endothelium burning nad tunica media swelling -> vein gets partially contracted after 0-10min -> AR detects best spots to do the injection sclerotherapy (Dextrose75%) and achieve the desired synergy. 1+1=3 effect: thermal effect + osmotic effect + Dextrose75% trapped because of vein collapse caused by laser shots. -20ºC air cooling CT ST nT CV 9 8 7 SV 6 5 4 nV 3 2 1 References 1- K Miyake, H Miyake.

All patients had feeder veins under the telangiectasias. Cryo-Laser and Cryo Sclerotherapy (D75%) guided by Augmented Reality is a new, effective and safe method. As soon as other groups starts to use the method in different populations it will be possible to have more conclusions about advantages and disadvantages (such as price of the devices). The lack of use of augmented reality in sample selection may be a bias to all telangiectasia treatment trials <- Q3
