In view of end-organ mal-perfusion (left kidney), deranged renal

        function and difficult to control hypertension, he was treated by

        thoracic endovascular aortic repair (TEVAR) with intentional coverage
        of left subclavian artery origin to achieve an adequate proximal landing

        zone, aiming to cover the entry intimal tear distal to left subclavian

        artery and redirect blood to true lumen. Intravascular ultrasound and
        intraoperative angiogram were used to ensure placement of guidewire

        along the true lumen. Left vertebral artery was hypoplastic and left

        common carotid artery to left subclavian artery bypass graft was
        deemed unnecessary. As left renal artery was perfused from the false                                                             Right renal

        lumen, left renal artery stenting was done through fenestration from                                                             artery from

        the true lumen. Finally, left subclavian artery embolization was done to                                                         true lumen                   Left renal artery

        prevent Type II endoleak.                                                                                                                                     fenestration
