Onyx embolisation safety profile in a Tertiary Care Centre, United Kingdom

We aim to analyze the safety profile of Onyx (an embolic agent) in Interventional Radiology (IR) as well as suggest time-to-intervention guidelines in extra-cranial acute bleeding. We analyzed outcomes of all patients who underwent embolisation using Onyx in the Interventional Radiology department in a tertiary care center from May 2015 - May 2020. Onyx has a good safety profile compared to conventional embolic agents, supporting its use in IR. In the absence of international guidelines, we recommended local time-to-intervention guidelines in the absence of national or IR society guidelines.

本研究旨在分析奥尼克斯（Onyx，一种栓塞剂）在介入放射学（Interventional Radiology，简称IR）中的安全性概况，并为颅外急性出血患者提出干预时机指南。本研究回顾性分析了2015年5月至2020年5月间，某三级医疗中心介入放射科所有使用奥尼克斯行栓塞术的患者的临床结局。与传统栓塞剂相比，奥尼克斯具有良好的安全性，支持其在介入放射学领域的临床应用。鉴于目前尚无国际指南，且缺乏国家级或介入放射学学会相关指南，本研究推荐适用于本地的颅外急性出血干预时机指南。
