INTRODUCTION
Deep venous stenting has gained increasing interest. More flexible venous stents are thought to gain superior clinical outcomes. This research evaluated the patency and clinical outcomes between more rigid stents and more flexible stents.
MATERIAL AND METHODS
The Venous Clinical Severity Score, Villalta, complication rates and patency rates were evaluated. The more rigid stents included the Sinus XL, the Veniti VICI and the Sinus Obliquus. The flexible group included the Zilver Vena or the Sinus Venous stents.
RESULTS
Differences in Venous Clinical Severity Score (p = 0.09) and Villalta score were found (p = 0.28). Tapering (0 versus 5, p = 0.03) and bad alignment were found (0 versus 5, p = 0.03). The rigid stents showed patency rates of 80, 86 and 92% compared to 88, 96 and 98% in the flexible group.
CONCLUSION
Dedicated venous stents show good patency outcomes and clinical results. Tapering and bad alignment between connecting stents are more frequently seen in more rigid stents.
引言
深静脉支架置入术越来越受到关注。人们认为更灵活的静脉支架能带来更好的临床效果。本研究评估了较硬支架和较灵活支架之间的通畅率及临床效果。
材料与方法
评估静脉临床严重程度评分、维拉塔评分、并发症发生率和通畅率。较硬支架包括Sinus XL、Veniti VICI和Sinus Obliquus。灵活组包括Zilver Vena或Sinus静脉支架。
结果
发现静脉临床严重程度评分存在差异（p = 0.09），维拉塔评分也存在差异（p = 0.28）。发现了锥度差异（0对5，p = 0.03）和排列不良差异（0对5，p = 0.03）。较硬支架的通畅率分别为80%、86%和92%，而灵活组为88%、96%和98%。
结论
专用静脉支架显示出良好的通畅效果和临床结果。在较硬支架中，连接支架之间的锥度和排列不良更为常见。
