Basic demographics, BMI, clinical class (C) of the CEAP classification, and the revised Venous Clinical Severity Score (VCSS)Before the intervention, with the patient standing, all varicose veins were carefully marked on the skin and DUS (CX50, transducer L12-3; Philips, Bothel, WA, USA) was performed to guide marking of the incompetent GSV or AASV, and its connection with the superficial varicosities. Both types of procedure were carried out under tumescent anaesthesia in an outpatient setting. Prophylactic low molecular weight heparin was not administered routinely.
