We evaluated a novel intravascular plug, the Hourglass peripheral embolisation device (PED). We describe, for the first time, the use of this device and discuss its potential applications. The device was deployed in nine patients over a six-month period at a single institution by two different operators. Five patients underwent renal artery embolisation, three underwent gonadal vein embolisation for a varicocele, and a single patient underwent embolisation of the gastroduodenal artery. We recorded the indications, success rate, and the procedure-related complication rate in all patients. We also evaluated the satisfaction of the operators with the device using a post-procedure evaluation form. Technical success was achieved in 9/9 (100%) cases. Unanimous feedback was obtained from the operators (100% agreement). The usability of the delivery system, device deployment, and device visibility under fluoroscopy were rated as easy in 9/9 (100%) cases. The ease of repositioning was rated as good in both cases where this was attempted. The device trackability was rated as good in 9/9 (100%) cases. There were no procedure-related complications. The Hourglass PED is potentially useful for the embolisation of small-to-medium sized vessels.
我们评估了一种新型血管内栓塞装置——沙漏形外周栓塞装置（PED）。我们首次描述了该装置的使用情况并讨论了其潜在应用。在六个月的时间里，两名不同的操作人员在一家机构为9名患者使用了该装置。5例患者接受了肾动脉栓塞，3例因精索静脉曲张接受了性腺静脉栓塞，1例患者接受了胃十二指肠动脉栓塞。我们记录了所有患者的适应证、成功率和与手术相关的并发症发生率。我们还使用术后评估表评估了操作人员对该装置的满意度。9/9（100%）例手术取得技术成功。操作人员给出了一致反馈（100%同意）。在9/9（100%）例手术中，输送系统的易用性、装置的部署以及在荧光透视下装置的可视性均被评为操作简便。在尝试重新定位的两例手术中，重新定位的难易程度被评为良好。在9/9（100%）例手术中，装置的可追踪性被评为良好。未发生与手术相关的并发症。沙漏形PED可能对中小血管的栓塞有用。
