Surgical removal of venous filter and snare complex in a patient with solitary left pelvic kidney
Abstract
Anticoagulation is used to prevent thromboembolism; inferior vena cava filters are an alternative in patients with contraindications to anticoagulation. Although it is safe and effective, there are recognized complications related to inferior vena cava filter placement. We describe the case of a young man with congenital solitary left pelvic kidney who required unique filter placement to suit the anatomy and surgical removal after entrapment of the filter-snare complex in the left internal iliac vein. Patients may also acquire solitary pelvic kidneys after renal transplantation. This anatomy poses unique challenges to venous filter placement and requires tailored management.
