A 66-year-old woman was admitted to hospital with severe backache. This patient had undergone ascending aortic replacement surgery to treat type A AD six months prior to the presentation. The medical history of the patient included hypertension for the past 25 years, nephrectomy due to nephrolithiasis eight years earlier, polio sequela and a motor deficit of the left leg.

Her systolic blood pressure was 130 mmHg on the right arm and 110 mmHg on the left arm. All arterial pulses were determined by manual examination. Contrast-enhanced computed tomography revealed a type B dissection flap involving the left subclavian artery with retrograde progression. The diameter of the true lumen had narrowed significantly to < 10 mm, and the total diameter (with false lumen) was 43.7 mm at the widest section. The peak aortic diameter was measured at 67.2 mm. We therefore initiated preparation for the TEVDAR surgery.....
