Mechanical thrombectomy in inferior vena cava thrombosis after caval filter placement: a report of three cases

We report our experience in treating three such patients using a mechanical thrombectomy device, which resulted in rapid symptomatic relief until anticoagulant therapy could be safely introduced.
