Our purpose was to demonstrate clinical efficacy of covered stent use in the peripheral vasculature. A 68-year-old man was transferred from an outlying hospital for evaluation and treatment of a pulsatile mass in his right groin after cardiac catheterization. Imaging with duplex ultrasound and diagnostic arteriogram demonstrated a 6-cm pseudoaneurysm (PSA) of the right superficial femoral artery (SFA) and an arteriovenous fistula (AVF) of the SFA and the profunda vein. Using a covered stent extending from the proximal SFA across the origins of the AVF and PSA, complete exclusion was attained. Follow-up ultrasound at 6 weeks revealed a patent stent, no AVF, and thrombosis of the PSA. Endovascular treatment of peripheral lesions (AVF/PSA) in an elective to semi-elective setting offers patients a safe, less invasive treatment option to consider over traditional open surgery. Consequently, a formidable reduction in incision length, wound infection, and postoperative immobility can be expected.

Purpose: The AVeNEW Post-Approval Study (AVeNEW PAS) follows upon results from the AVeNEW IDE clinical trial and was designed to provide additional clinical evidence of safety and effectiveness using the Covera™ Vascular Covered Stent to treat arteriovenous fistula (AVF) stenoses in a real-world hemodialysis patient population.
Materials And Methods: One hundred AVF patients were prospectively enrolled at 11 clinical trial sites in the USA and treated with the covered stent after angioplasty of a clinically significant target stenosis. The primary safety outcome was freedom from any adverse event that suggests the involvement of the AV access circuit evaluated at 30 days.

Objectives: Mal-deployment of the thoracic endovascular aortic repair (TEVAR) stent graft during a frozen elephant trunk (FET) procedure for an acute type A aortic dissection (ATAAD) leads to devastating complications. We report a hemiarch replacement with TEVAR stent graft covering the aortic arch vessels salvaged through an endovascular approach.
Methods: A 69-year-old man with ATAAD in 2018, status post-hemiarch repair with TEVAR, presented in 2023 with progressive dizziness/syncope and lower extremity hypertension with inability to tolerate anti-hypertensives.

Despite the unique properties of clay nanocomposites for cardiovascular applications, there are few data on the hemocompatibility of these nanomaterials. This study represents the first comprehensive investigation of the hemo/biocompatibility of clay nanocomposites . Nanocomposite coatings of polylactic acid (PLA)-polyethylene glycol (3 wt %)-Cloisite20A nanoclay (3 wt %) were produced using electrospraying technique as potential drug-eluting stent (DES) coatings.

Percutaneous Coronary Intervention (PCI) is a treatment method that involves reopening narrowed arteries with a balloon catheter that delivers a cylindrical, mesh-shaped implant device to the site of the stenosis. Currently, by applying a coating to a bare metal stent (BMS) surface to improve biocompatibility, the main risks after PCI, such as restenosis and thrombosis, are reduced while maintaining the basic requirements for the mechanical behavior of the stent itself. In this work, for the first time, the development and optimization process of the spatial structure of the Co-Cr stent (L-605) with a graphene-based coating using cold-wall chemical vapor deposition (CW-CVD) to ensure uniform coverage of the implant was attempted.
