We report a case of a type B aortic dissection with an aneurysm treated by the replacement of the proximal descending thoracic aorta via the reversed elephant trunk technique. A 48-year-old asymptomatic man was diagnosed with a type B aortic dissection, moderate aortic regurgitation, and a good biventricular function in March 2012. Four years later (April 2016), a contrast-enhanced computed tomography examination revealed an aneurysmal dilatation in the patient’s descending thoracic aorta with a thrombosis in the proximal part of the false lumen, which warranted surgical repair. He underwent type B aortic dissection repair through the left posterolateral thoracotomy. Three months after the surgery, the patient developed a type A aortic dissection with severe aortic regurgitation, which was successfully managed via a Bentall procedure with arch replacement facilitated by the reversed elephant trunk technique performed during the initial surgery through thoracotomy. At 2 years follow-up, the patient was doing well with a normal left ventricular function.
