Totally percutaneous endovascular abdominal aortic aneurysm repair (PEVAR) using suture-mediated closure devices (SMCDs) has several well-established advantages over standard open femoral exposure as a direct consequence of being less invasive and having shorter times to hemostasis and procedure completion. The first multicenter randomized controlled trial designed to assess the safety and efficacy of PEVAR and to compare percutaneous access with standard open femoral exposure was recently published (the PEVAR trial). The PEVAR trial demonstrated that percutaneous endografting is safe, effective, and noninferior to standard open femoral exposure among trained operators. The study reaffirmed the results of several recent single center and nonrandomized studies, demonstrating that percutaneous access facilitated shorter procedures, shorter times to secure hemostasis, and improved quality of life for patients. As PEVAR has gained popularity among patients and physicians, refinements to the technique and patient selection process have been made. There has been growing interest in treating patients with anatomical characteristics previously thought to be unsuitable for PEVAR, such as common femoral artery (CFA) calcifications, scarred groins, small CFA diameter, and high patient body mass index (BMI). However, observance of strict procedural technique and consideration for patient selection criteria remain paramount in achieving acceptable technical success rates with PEVAR.
使用缝线介导闭合装置(SMCD)的完全经皮血管腔内腹主动脉瘤修复术(PEVAR)相较于标准开放股动脉暴露具有多项公认的优势,这是其侵入性较小、止血时间和手术完成时间较短的直接结果。最近发表了第一项旨在评估PEVAR的安全性和有效性,并将经皮入路与标准开放股动脉暴露进行比较的多中心随机对照试验(PEVAR试验)。PEVAR试验表明,在训练有素的操作者中,经皮血管内植入术是安全、有效的,且不劣于标准开放股动脉暴露。该研究重申了近期几项单中心和非随机研究的结果,表明经皮入路可使手术时间缩短、止血时间缩短,并改善患者的生活质量。随着PEVAR在患者和医生中越来越受欢迎,该技术和患者选择过程也得到了改进。治疗先前被认为不适合PEVAR的解剖学特征患者,如股总动脉(CFA)钙化、腹股沟瘢痕、CFA直径小和患者高体重指数(BMI),受到了越来越多的关注。然而,在通过PEVAR实现可接受的技术成功率方面,严格遵守手术技术和考虑患者选择标准仍然至关重要。
