ABSTRACT

Given the complex embryogenesis of the inferior vena cava (IVC), anatomic variations are commonly encountered. Duplication of the IVC occurs in up to 2.8% of the population. Though asymptomatic, a duplicated IVC has important clinical implications when attempting caval filtration. We present the case of a 45- year-old male with factor V leiden and protein C deficiency, who required cessation of warfarin anticoagulation in preparation for cervical laminectomy. The patient had a duplicated IVC and required placement of a caval filter in each IVC.
