The penumbra occlusion device (POD) is a recently developed metallic coil with a unique anchor segment. The purpose of this study was to investigate the anchoring function of the POD for embolization of medium-sized vessels in detail.
We reviewed a series of cases of proximal embolization of medium-sized vessels in which the POD was used. Endovascular outcomes and complications were assessed. The distance between the distal end of the first-indwelled POD and the microcatheter tip was defined as the "landing distance," and this was also evaluated via fluoroscopic analysis.
POD deployment was successful in 17 of 18 patients. The median landing distance was 9.6 mm, and no distal POD migration was observed after the formation of anchor loops.
The specific anchoring function of the POD enables effective proximal occlusion of medium-sized vessels.
半暗带封堵装置（POD）是一种最近研发的带有独特锚定节段的金属线圈。本研究的目的是详细研究POD用于中等大小血管栓塞的锚定功能。
我们回顾了一系列使用POD进行中等大小血管近端栓塞的病例。评估血管内治疗结果和并发症。将首个植入的POD远端与微导管尖端之间的距离定义为“着陆距离”，并通过荧光透视分析进行评估。
18例患者中有17例POD成功部署。中位着陆距离为9.6毫米，形成锚定环后未观察到POD向远端迁移。
POD的特定锚定功能能够有效实现中等大小血管的近端封堵。
