Late collapse of a thoracic endoprosthesis.

Thoracic stent graft collapse is a rare complication of thoracic endovascular aortic repair that is mostly asymptomatic and occurs ≤ 3 months of the procedure. We describe the case of a 36-year-old man who presented with symptomatic endograft collapse 38 months after an initial thoracic endovascular aortic repair that was performed for traumatic aortic transection. He had sudden and complete loss of bilateral lower extremity motor and sensory functions (spinal cord ischemia) and anal sphincter tone. The patient was successfully treated with redo thoracic endovascular aortic repair, followed by open conversion and device explantation.
