Clinical Outcomes of Carotid Artery Stenting for Carotid Artery Stenosis in Maintenance Hemodialysis Patients.

Department of Neurosurgery, Osaka University Graduate School of Medicine.
Most previous large studies of carotid artery stenting (CAS) in maintenance hemodialysis patients are old-era, do not describe the types of stents and method of protection, and their effectiveness is unknown. CAS has progressed remarkably, and tailor-made CAS is now possible in hemodialysis patients according to the lesion. We aimed to analyze the outcomes of CAS in maintenance hemodialysis patients treated in our institution.

Article Synopsis
- The report investigates the safety and effectiveness of 3D-printed aortic models in aortic surgery, especially regarding their sterilization and modification for creating personalized endoprostheses.
- Five identical models were made using patient data, with two sterilized, two disinfected, and one untreated to evaluate any changes from these processes.
- The findings showed no significant structural alterations in the models post-treatment, and both sterilized and disinfected models were free of pathogens, supporting their potential clinical use.
[Preoperative Simulation of Neuroendovascular Therapy Using a Three-Dimensional Printer Model of a Tailor-Made Hollow Cerebral Aneurysm].

Several studies have reported the importance of preoperative simulations. This report describes the methods and utility of neuroendovascular treatment using a three-dimensional(3D)-printed hollow cerebral aneurysm model. This model was created using a stereolithography apparatus-type 3D printer with digital imaging and communications in medicine data from 3D digital subtraction angiograms.

In order to improve the percutaneous treatment of coronary artery calcifications (CAC) before stent implantation, methods such as rotational atherectomy (RA), orbital atherectomy (OA), and coronary intravascular lithotripsy (IVL) were invented. These techniques use different mechanisms of action and therefore have various short- and long-term outcomes. IVL employs sonic waves to modify CAC, whereas RA and OA use a rapidly rotating burr or crown.

Vascular stents (VS) have revolutionized the treatment of cardiovascular diseases, as evidenced by the fact that the implantation of VS in coronary artery disease (CAD) patients has become a routine, easily approachable surgical intervention for the treatment of stenosed blood vessels. Despite the evolution of VS throughout the years, more efficient approaches are still required to address the medical and scientific challenges, especially when it comes to peripheral artery disease (PAD). In this regard, three-dimensional (3D) printing is envisaged as a promising alternative to upgrade VS by optimizing the shape, dimensions and stent backbone (crucial for optimal mechanical properties), making them customizable for each patient and each stenosed lesion.
