Polyethylene debris following metal-on-metal total hip arthroplasty as a rare cause of symptomatic iliac vein compression and iliofemoral deep venous thrombosis

Abstract

Extrinsic venous compression of the pelvic vasculature is associated with deep venous thrombosis of the iliac veins. Inflammatory pseudotumors are a known rare complication of metal-on-metal and metal-on-polyethylene hip resurfacing, We report the case of a 73-year-old woman with such a pseudotumor compressing the left iliac vein with associated deep venous thrombosis extending distally into the lower leg. In this case, we demonstrate safe and effective use of endovascular techniques, including percutaneous mechanical thrombectomy and iliac vein stenting, followed by revision total hip arthroplasty and excision of the pseudotumor.
