Comparing polymer-filled versus self-expanding endografts in Chinese patients:

IntroductionWe performed a single-center nonrandomized study on patients who underwent endovascular aneurysm repair using polymer-filled or other self-expanding endografts.MethodsConsecutive patients with asymptomatic infrarenal abdominal aortic aneurysms who underwent endovascular repair were retrospectively reviewed. They were divided into a polymer-filled (n = 20) or self-expanding group (n = 42). Baseline characteristics, operative mortality and morbidity, and follow-up data were compared.ResultsAneurysm diameter, neck and iliac morphologies did not differ between the two groups. Technical success was 100%. The 30-day mortality was 0% and 2.4% in the polymer-filled and self-expanding group, respectively. At a mean follow-up of 17 months, the changes in sac size were −2.1 mm and −5.1 mm (p = 0.144) at one year, and −3.5 mm and −7.7 mm (p = 0.287) at 2 years in the polymer-filled and self-expanding group, respectively. The polymer-filled group had 7 (35%) type II endoleaks, and the self-expanding group ...
