Deploying coils accurately in high-flow vessels can be challenging. Particularly with larger vessels, obtaining the stability to prevent downstream coil migration is of paramount importance. This is particularly true in the embolization of pulmonary arteriovenous malformations, in which distal coil migration to the systemic circulation can have disastrous consequences. Although detachable coils/balloons, hydrocoils, and plugs mitigate some of this risk, these devices are costly and not always readily available. Furthermore, there are times when a large plug may not be deliverable to the intended target, necessitating use of coils instead. This chapter describes two separate techniques to secure coils at their site of deployment—the anchor technique and the scaffold technique.
