A case of duplicated inferior vena cava with bilateral iliac vein compression

Duplicated inferior vena cava with bilateral iliac vein compression is extremely rare. We report a case of an 87-year-old man presented with bilateral lower extremity swelling, who was noted to have duplicated inferior vena cava, as revealed by computed tomography angiography (CTA). This revealed bilateral iliac vein compression caused by surrounding structures. Anticoagulant treatment combined with stent implantation completely alleviated this chronic debilitating condition during the follow-up of 2 months with no recurrence.
