Outcome

Type Measure Description Time frame Safety issue
Primary Percentage diameter reduction Compare the percentage diameter reduction measured by intravascular ultrasound (IVUS) and venography 1 month
Primary Percentage area reduction Compare the percentage area reduction measured by IVUS and the calculated percentage area reduction measured by venography 1 month
Secondary CEAP score Improvement in Clinical, Etiology, Anatomy, Pathophysiology (CEAP) score 18 months
Secondary Primary patency Primary patency can be defined as without additional revascularization of the target lesions, the target vessels are still patent which measured by ultrasound or magentic resonance venography (MRV) and the diameter reduction is <50% during follow-up period. 18 months
Secondary Secondary patency Secondary patency can be defined as: with additional revascularization of the target lesions after the first surgery in our department, the target vessels are still patent which measured by ultrasound or magentic resonance venography (MRV) and the diameter reduction is <50% during follow-up period. 18 months
