Percutaneous thrombectomy using a novel single-session device for acute ilio-caval deep vein thrombosis

A 53-year-old man developed acute left leg pain and edema 2 weeks after lumbar interbody fusion. A computed tomography venogram demonstrated acute thrombosis extending from the deep veins of the calf all the way to and including the common iliac vein owing to external compression of common iliac vein secondary to extruded bone graft material. Endovascular intervention without the use of thrombolysis was performed using a novel percutaneous mechanical thrombectomy system (ClotTriever, Inari Medical, Irvine, Calif), allowing clot removal in single session. Clot removal and stenting were performed with resolution of symptoms and only mild swelling with prolonged standing at the 6-month follow-up.
