Complicación de filtro de vena cava inferior con penetración hacia la aorta abdominal

Introduction: inferior vena cava filters (IVCF) are medical devices designed to prevent pulmonary embolism in patients with contraindications to anticoagulation, particularly those at high risk for bleeding or with a history of anticoagulant-related complications. Case report: we present the case of a 48-year-old patient with polytrauma following a motorcycle accident. During her recovery, she developed bilateral deep vein thrombosis in the lower limbs. Due to her high hemorrhagic risk, a BARD-type IVCF was implanted. One month later, the patient developed persistent lumbar pain. After an unsuccessful attempt at endovascular removal, imaging confirmed that the filter had perforated the vena cava wall and extended into the infrarenal abdominal aorta. Subsequently, an open surgical extraction was performed with a favorable clinical outcome. Discussion: the incidence of inferior vena cava filter perforation is up to 34 %, with 8 % of cases being symptomatic and 5 % requiring urgent surgical intervention. Proximity to structures such as the aorta and renal arteries increases the risk of severe complications, such as aneurysms or dissections. This case highlights the need for multidisciplinary management and suggests that, in the presence of severe complications, open surgical extraction may be considered a safe alternative when endovascular techniques fail.
