Reverse sheathing technique for iliocaval thrombectomy in the setting of IVC filters

Abstract

Abstract The Inari ClotTriever system (Inari Medical, Irvine, California) is safe and effective for the treatment of DVT. However, because it consists of a 31 cm coring device and collection bag that must be extended for use, application may be precluded by available intravascular “running room”, such as in the presence of an IVC filter. Here we present a technique for bypassing IVC filters via retrograde deployment of the ClotTriever within a sheath, as illustrated in three cases. This technique extends the applicability of the ClotTriever to locations in which its length would otherwise preclude use.
