A Case of Critical Limb Ischemia Resulting from Iliac Stent Compression Caused by Severe Displacement of Artificial Hip Joint
An 80-year-old female with osteoarthritis had undergone left total hip replacement, and self-expandable stents were placed to relieve bilateral iliac artery stenosis eight years ago in the previous hospital. Five years later, serious complications of artificial joint infection occurred after a second left total hip replacement in the patient, after which she was bedridden . Three years later, she was admitted to our hospital because of the appearance of an ulcer and resting pain on her toes, both of which had developed over the previous 2 months . Contrast medium–enhanced computed tomography revealed that her left iliac artery was completely obstructed from the level of the ostium, the iliac stent was severely bent, and the artificial femoral head was displaced into the abdominal space due to the destruction of the left acetabulum. Rotational fluoroscopy revealed that the iliac stent had been flattened as a result of the compression by the displaced artificial femoral head. Therefore, this flattened stent was considered to be a cause of critical limb ischemia. Endovascular treatment was undertaken to salvage her limb. Revascularization and limb salvage were successful.
