ABSTRACT
A 53-year-old man presented with a painful, non-healing ischemic ulcer of the left fifth toe. The patient was initially treated conservatively for 4 months with local debridement and medication with antiplatelet therapy but his symptoms and the ulcer was refractory. A computed tomography revealed a bulky, irregular, gritty, localized calcification of the infra-renal aorta and was compatible with the so-called “coral reef aorta”. Angiography confirmed the findings of the CT scan, and there was no evidence of occlusive lesions in the distal runoff vessels. A diagnosis of blue toe syndrome secondary to infra-renal coral reef aorta was made. In order to prevent further embolization, the patient underwent aortic excision with PTFE grafting via a retroperitoneal incision. In order to increase the microcirculation of the toe and to aid in the healing of the ulcer, a lumbar sympathectomy was performed simultaneously. The ulcer healed completely on postoperative day 47. The treatment method for coral reef aorta depends on the presence or absence of global ischemia of the lower extremity and embolic complications.
