Case report: Thoracic Endovascular Aneurysm Repair to Treat Recurrent Lower Limb Ischemia Secondary to Occlusion of Axillofemoral Bypass

Abstract Introduction A case of malperfusion in which the patient presented with aortic dissection is presented. Presentation of case A 69-year-old man with an acute aortic dissection (Stanford type B) had lower limb ischemia. Axillary-femoral bypass was performed, and his lower limb ischemia improved. Eight months after the onset of acute aortic dissection, he again had lower limb ischemia. Contrast-enhanced computed tomography showed axillary-femoral bypass occlusion and true lumen collapse, compressed by the increased false lumen pressure in the aorta. Thoracic endovascular aortic repair (TEVAR) was performed for entry closure. His lower limb ischemia was improved by TEVAR. Discussion One of the complications of type B aortic dissection is malperfusion. Endovascular therapy is a first step in treating the malperfusion of type B aortic dissection. It is important to seal the entry for the treatment of malperfusion. Conclusion If there is an entry, it is important to seal it for the treatment of malperfusion.
