Endovascular repair of spontaneous infrarenal aortic dissection presenting as severe lower extremity ischaemia.

We report a 90-year old man who presented with severe lower extremity ischaemia due to spontaneous dissection of a non-aneurysmal infrarenal abdominal aorta. The aortic lesion was treated using an aorto-uni-iliac stent-graft with contralateral common iliac artery occlusion and femoro-femoral cross-over bypass. The patient underwent digital amputation and debridement of the foot four weeks post-operatively. At 12 months follow-up, he remains symptom-free with an excluded dissection, patent reconstruction and healed foot.
