摘要

开窗主动脉腔内修复术后的亲水聚合物栓塞（HPE）综合征是一种罕见且具有破坏性的并发症。目前，尚无数据将临床HPE与可能产生聚合物的特定候选血管内装置联系起来。我们报告两例HPE患者接受开窗血管内主动脉修复术。使用真皮活检样本和18个常规使用的设备，扫描电子显微镜和能量色散x射线光谱学在设备和位于真皮毛细血管的栓塞物质之间的元素特征上建立了匹配。使用大约1.5的碳氧比，我们确定了8个带有聚合物材料的装置，怀疑是栓塞的来源。

Evaluation of possible sources of polymer embolization after fenestrated aortic repairs mimicking spinal cord ischemia

Hydrophilic polymer embolization (HPE) syndrome after fenestrated endovascular aortic repair is a rare and devastating complication. Currently, no data exist linking clinical HPE to specific candidate endovascular devices from which the polymer may have arisen. We report two cases of HPE in patients who underwent fenestrated endovascular aortic repairs. Using a dermal biopsy sample and 18 routinely used devices, scanning electron microscopy and energy dispersive x-ray spectroscopy established matches in elemental signature between the devices and embolized material located in dermal capillaries. Using a carbon to oxygen ratio of approximately 1.5, we identified eight devices with polymer material suspected to be the source of the embolization.

期刊介绍： Journal of Vascular Surgery Cases and Innovative Techniques is a surgical journal dedicated to publishing peer review high quality case reports, vascular images and innovative techniques related to all aspects of arterial, venous, and lymphatic diseases and disorders, including vascular trauma, malformations, wound care and the placement and maintenance of arterio-venous dialysis accesses with an emphasis on the practicing clinician. The Journal seeks to provide novel and timely information to vascular surgeons, interventionalists, phlebologists, wound care specialists, and allied health professionals involved with the management of patients with the entire spectrum of vascular disorders.
