研究目的:

本研究以动静脉移植物内瘘狭窄最常见的静脉吻合口狭窄为研究对象,使镍钛合金紫杉醇洗脱血管支架与覆膜支架开展多中心、前瞻性、随机、对照临床研究,以期探索镍钛合金紫杉醇洗脱血管支架在治疗该病变方面是否不劣于覆膜支架,为优化该病变治疗方案提供依据。  

Objectives of Study:

This study focused on venous anastomotic stenosis, the most common type of arteriovenous graft stenosis. A multicenter, prospective, randomized controlled clinical trial was conducted to compare nitinol paclitaxel-eluting vascular stents with covered stents. The aim was to explore whether nitinol paclitaxel-eluting stents are non-inferior to covered stents in the treatment of such lesions, so as to provide evidence for optimizing the therapeutic strategy for this disease.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

研究病历记录要求:采用纸质CRF表进行数据收集,并对数据采集者进行数据采集及CRF填写的规范化培训,保证数据采集的完整性和可行性。在研究结束后,采用Redcap建立数据库,将收集的病例资料的数据进行赋值后由经过统一培训的专人双录入,并通过软件检验审核、逻辑检查,进一步确保电子数据库数据的准确性。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Study Medical Record Requirements: Data collection will be performed using paper-based CRFs. Data collectors will receive standardized training on data collection and CRF completion to ensure the completeness and validity of data acquisition. After study completion, a database will be established using Redcap. The collected case data will be coded and then double-entered by uniformly trained dedicated personnel. The accuracy of the electronic database will be further ensured through software validation review and logical checks.
