The Amplatzer Vascular Plug (AVP) was created for peripheral embolization as a modification of the family of Amplatz septal occluders used in the treatment of congenital heart malformations. The device has evolved over the years and multiple versions have been launched into the market. Each of the versions of the device has some important modifications in terms of the size of the introducer's system, number of layers, and resultant thrombogenicity. It is very important for the operator to become familiar with the unique features of the AVP, and to understand the advantages and limitations of each model in the AVP family to achieve an optimal embolic result. The purpose of this article is to review the evolution and current clinical applications of the AVP in the field of interventional radiology, with emphasis on the advantages and limitations of this device in comparison with other embolization agents.
Amplatzer血管封堵器(AVP)是作为用于治疗先天性心脏畸形的Amplatz房间隔封堵器系列的一种改进而设计用于外周栓塞的。多年来该装置不断发展,多个版本已投放市场。该装置的每个版本在导入系统尺寸、层数以及由此产生的血栓形成性方面都有一些重要改进。对于操作者来说,熟悉AVP的独特特征,并了解AVP系列中每个型号的优缺点以获得最佳栓塞效果非常重要。本文的目的是回顾AVP在介入放射学领域的发展历程和当前临床应用,重点是该装置与其他栓塞剂相比的优缺点。
