Abstract
As large-bore mechanical thrombectomy is increasingly used to treat deep vein thrombosis (DVT), uncommon device-related adverse events, including catheter deformation, fracture, and retained intravascular foreign bodies, may be encountered. This study describes the case of a 60-year-old man with right lower-extremity DVT and pulmonary embolism in whom a Lightning Bolt 7 catheter (Penumbra) fractured during aspiration thrombectomy, resulting in a retained catheter fragment within the femoral vein that was refractory to snare retrieval attempts. During a subsequent procedure, the ClotTriever BOLD Thrombectomy System (Inari Medical), was used to successfully achieve simultaneous extraction of the embedded catheter fragment in its entirety and acute thrombus, restoring inline venous flow. This case highlights a salvage strategy using a large-bore, mechanically distinct thrombectomy device to retrieve a retained catheter fragment while simultaneously treating acute DVT.
