Anterior lumbar interbody fusion (ALIF) is a standard approach for the surgical management of patients with severe degenerative disease at the L4-L5 and lumbosacral (L5-S1) levels. ALIF is performed through retroperitoneal exposure but harbors a small risk of major vascular injury. In this case, we describe an emergent endovascular repair of an external iliac vein injury that occurred during ALIF with long-term follow-up. We discuss specific strategies in the decision making and technique that led to a successful outcome in this case. Endovascular stent grafting is a potential bailout option for serious iliac vein injury.

Temporary interruption of the inferior vena cava is the recommended treatment to prevent pulmonary embolism in patients with venous thromboembolism (VTE) and active contraindications for therapeutic anticoagulation. In patients with mega cava (diameter >30 mm), temporary inferior vena cava filters are contraindicated. In the present report, we have described the successful placement and retrieval of bilateral iliac vein filters in two patients with VTE, mega cava, and active contraindications for therapeutic anticoagulation. At the last follow-up, both patients had recovered without recurrent VTE and had had all filters successfully retrieved without complications.
