The AngioVac system, designed for suction during extracorporeal bypass, is used to aspirate masses, thrombi, and other undesirable material from the cardiovascular system. To date, it has been used extensively in the venous system and right side of the heart; however, its use in the arterial system has been limited because of smaller vessel sizes and the requirement for a 26F sheath. We report the case of a 45-year-old woman with a history of angiosarcoma who presented with acute embolic events that affected her spleen and lower extremities. We removed a large mobile mass en bloc from her distal thoracic aorta by using the AngioVac system as an alternative to surgical resection. The patient recovered with no recurrence. We discuss the benefits and challenges of using the AngioVac within small vessels of the arterial system.
AngioVac 系统专为体外循环时的抽吸而设计，用于从心血管系统中抽吸肿块、血栓和其他不良物质。迄今为止，它已广泛应用于静脉系统和右心，但由于血管较小且需要 26F 鞘，其在动脉系统中的应用受到限制。我们报告了一例患有血管肉瘤的 45 岁女性，她因急性栓塞事件导致脾脏和下肢受累。我们使用 AngioVac 系统整块切除了她的远端胸主动脉中的一个大的移动肿块。患者无复发，恢复良好。我们讨论了在动脉系统的小血管中使用 AngioVac 的益处和挑战。
