This clinical study followed a prospective, multicentre, single-arm design with the application of an objective performance goal. Patients diagnosed with symptomatic iliofemoral venous obstruction who met the eligibility criteria of this study were enrolled and treated with the Inno-Xmart venous stent system. The safety endpoints included the assessment of stent fracture, satisfaction of delivery system and 12-month incidence rate of major adverse events (MAEs). The primary efficacy endpoint focused on evaluating the 12-month primary patency rate through venography as determined by core laboratory. Secondary efficacy endpoints included surgical success rate, 6-month primary patency rate and the changes in quality of life from baseline to 6- and 12-month follow-up intervals. Between September 18, 2019, and April 26, 2021, 193 patients were successfully enrolled across 18 research institutions. The surgical success rate was 95.3% (184/193), the 12-month MAE rate was 5.1% (9/178) with no stent fractures or migrations. The 12-month primary patency rate for the participants was 96.1%, significantly surpassing the literature-derived objective performance of 80% (95% confidence interval [CI], 92.1-98.4; P < 0.0001). In addition, the mean venous clinical severity score (VCSS) and Chronic Venous Disease Quality of Life Questionnaire (CIVIQ) scores at the 6- and 12-month follow-ups were significantly lower than the preoperative scores (P < 0.001). The innovative, dedicated braided venous stent designed to address symptomatic iliofemoral venous obstruction demonstrates a high technical success rate, low complication rates, and impressive mid-term (12-month) patency. It effectively enhanced the quality of life for patients and holds promising prospects for a wide range of applications.
