Stents are ubiquitously utilized in coronary and peripheral arterial disease. Interventional nephrologists, however, place stents in the venous outflow of the arteriovenous access. Stenosis is the predominant pathology that causes access dysfunction and will ultimately lead to thrombosis if uncorrected. Angioplasty and stent deployment are the current techniques available to combat stenosis. From initial bare metal stainless steel stents, the current generations of stents used are predominately covered nitinol stents. The latest randomized control trials reveal that stents decrease the number of interventions required to maintain patency but do not improve the overall access survival. Furthermore, bare metal stents have been shown to be inferior to stent grafts. This review discusses indications for stent deployment in the hemodialysis access, the current evidence for their use, and briefly touches on their complications.

The guide extension-facilitated ostial stenting (GEST) technique uses a guide extension catheter (GEC) to improve stent delivery during primary coronary angioplasty (PCI). GECs are used for stent delivery into the coronary arteries of patients with difficult anatomy due to tortuosity, calcification, or chronic total occlusion (CTO) vessels. Stent and balloon placement has become challenging in patients with increasing lesion complexity due to tortuosity, vessel morphology, length of the lesion, and respiratory movements.

We present a case of an adult patient with a large symptomatic fusiform basilar artery aneurysm. This video demonstrates the ease of deploying the new Pipeline™ Vantage Flow Diverter compared to the Flex model in the same vessel. The Flex and Vantage have different deployment techniques-as using the Flex maneuvering technique on the Vantage may damage the braid.

PDA stenting is increasingly utilized for patients with ductal-dependent pulmonary blood flow. Predicting optimal stent length prior to and during the intervention remains a challenge. The utility of pre-catheterization computed tomography angiography (CTA) to predict stent length was evaluated.

Current limitations in implant design often lead to trade-offs between minimally invasive surgery and achieving the desired post-implantation functionality. Here, we present an artificial intelligence inverse design paradigm for creating deployable implants as planar and tubular thermal mechanical metamaterials (thermo-metamaterials). These thermo-metamaterial implants exhibit tunable mechanical properties and volume change in response to temperature changes, enabling minimally invasive and personalized surgery.

Transcatheter aortic valve replacement (TAVR) is a common treatment for severe aortic stenosis (AS), but it carries the risk of severe complications, including device embolization. We present a case of a TAVR valve embolization into the left ventricular outflow tract (LVOT), diagnosed with transesophageal echocardiography (TEE) shortly after device deployment. The dislodged valve was successfully retrieved from the LVOT into the aorta, flattened, and stabilized with a thoracic endovascular aneurysm repair (TEVAR) stent, enabling the successful implantation of a new TAVR valve.
