: The saphenous vein graft (SVG) remains the most frequently used conduit worldwide, despite its common disadvantage of early graft failure. To solve the problem and reduce the SVG damage, Souza implemented a new technique where a vein is harvested with surrounding fascia and fat tissue (the so-called no-touch technique). . A prospective study conducted from February 2019 to June 2024 included 23 patients who underwent myocardial revascularization using a no-touch vein, with follow-up control examinations using computed tomographic angiography to detect graft stenosis or occlusion. . Of the entire patient group, 17 (73.9%) were male, with a mean age of 67.39 ± 7.71 years. The mean follow-up period was 25 months. There were no major adverse cardiovascular or cerebrovascular events (MACCEs) during hospitalization, although one patient died in the hospital. Another patient died due to malignancy, but no MACCEs occurred during the follow-up period. According to multi-slice CT coronary angiography, the results were impeccable, with an astonishing 100% patency observed in all 20 IMA grafts and 58 no-touch SVGs examined. . The excellent patency rate during the early follow-up period confirmed that the no-touch technique is a good option for surgical revascularization.
大隐静脉移植物（SVG）仍然是全球使用最广泛的血管移植物，尽管它存在早期移植物失败的常见缺点。为了解决这个问题并减少 SVG 损伤，Souza 实施了一种新技术，即采集带有周围筋膜和脂肪组织的静脉（所谓的不接触技术）。一项前瞻性研究于 2019 年 2 月至 2024 年 6 月进行，共纳入 23 例使用不接触静脉进行心肌血运重建的患者，通过计算机断层血管造影术进行随访控制检查，以检测移植物狭窄或闭塞。在整个患者组中，17 例（73.9%）为男性，平均年龄为 67.39±7.71 岁。平均随访时间为 25 个月。住院期间无重大心血管或脑血管不良事件（MACCEs），尽管有 1 例患者在住院期间死亡。另 1 例患者因恶性肿瘤死亡，但随访期间无 MACCEs 发生。根据多层 CT 冠状动脉造影，结果令人惊叹，20 例 IMA 移植血管和 58 例不接触 SVG 均观察到 100%通畅。在早期随访期间良好的通畅率证实，不接触技术是外科血运重建的一个不错选择。
