Current Status of Percutaneous Endografting.
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.
