Double vena cava filter insertion in congenital duplicated inferior vena cava: a case report and literature review

Abstract

The complex embryogenesis of the inferior vena cava (IVC) may result in several anomalies, often presenting as an incidental radiological finding. In addition to the differential diagnosis with pathological lesions, recognizing IVC defects is crucial for invasive procedures. This report describes a patient with a right femoral vein thrombosis who could not be given anticoagulant therapy due to a concomitant acute cerebral hemorrhage. He was found to have an asymptomatic duplicated IVC with interiliac communication. A filter had to be inserted in each vena cava to prevent pulmonary embolism. A review of the literature dealing with the few reported cases of filter insertion in congenital duplicated IVC is presented.
