Arteriovenous malformations (AVMs) may be cured by injecting liquid embolic agents such as Onyx. Reflux, however, can sometimes be difficult to control and may jeopardize a complete embolization. The pressure cooker technique (PCT) was designed to create an anti-reflux plug by trapping the detachable part of an Onyx-compatible microcatheter with coils and glue in order to obtain wedge-flow conditions, thereby enabling a better understanding of macrofistulous AVMs and a more comprehensive, forceful and controlled Onyx embolization. The PCT might enlarge the range of AVMs amenable to endovascular cure. Three illustrative cases are presented.
动静脉畸形（AVM）可通过注射如Onyx等液体栓塞剂治愈。然而，反流有时可能难以控制，并且可能危及完全栓塞。压力锅技术（PCT）旨在通过用线圈和胶水困住与Onyx兼容的微导管的可分离部分来创建一个抗反流塞，以获得楔形血流条件，从而更好地了解大型瘘管型AVM，并实现更全面、有力和可控的Onyx栓塞。PCT可能会扩大适合血管内治愈的AVM范围。本文介绍了三个说明性病例。
