Objective: Until now, giant intracranial aneurysms (GIAs) have in many cases been a vascular disease that was difficult or impossible to treat, not least due the lack of availability large-format stent. In this multicentre study, we report on first five clinical applications Accero®-Rex-Stents (Acandis, Pforzheim, Germany) successful treatment fusiform cerebral aneurysms. Material and Methods: The are self-expanding, braided, fully radiopaque Nitinol stents designed for aneurysm treatment....

This paper describes the design, control and implementation of a sensorized robotic platform for versatile rehabilitation stroke patients living with lower extremity neuromuscular deficit. The proposed device is composed six-degree-of-freedom actuation mechanism large workspace regimens. With small footprint, lightweight, low-cost design wireless interface this portable well-suited at-home in-clinic use. A custom force/torque sensor was developed to measure real-time patient forces, an...

Background Vein of Galen malformations are congenital arteriovenous primarily treated by endovascular embolization via transarterial or transvenous approaches. can be utilized to close the malformation but may difficult in patients with venous stenosis blockages, which drive hypertension and lead significant neurologic consequences. Here, we illustrate atypical placement an intracranial sinus stent improve outflow after pediatric vein malformation. Methods A retrospective review clinical...

Background and purpose To evaluate the durability safety of complete intracranial aneurysm occlusion at one year using low-profile braided LVIS EVO stent. Materials methods This is a retrospective, monocentric, observational study unruptured wide-necked aneurysms treated with stent-through-balloon technique after balloon-assisted hydrocoil embolization. Imaging clinical data were assessed by two blinded independent neuroradiologists neurologists, respectively. Primary endpoint was...

e13508 Background: Oncology infusion centers are increasingly focused on improving operational efficiencies and patient satisfaction, while maintaining quality care. One key component is optimizing chair time, which has been especially important for safety during the COVID-19 pandemic to reduce risk of transmission. Many infusions require antihistamine premedication hypersensitivity reactions (IRs). The two IV options diphenhydramine cetirizine, have a quicker onset than oral can be...
