{Reference Type}: Case Reports {Title}: An operative case of pseudocoarctation with chronic dissection. {Author}: Yoshitatsu M;Kakizawa Y;Misumi Y;Shirasaki Y;Kitahara M;Nishi H; {Journal}: Asian Cardiovasc Thorac Ann {Volume}: 31 {Issue}: 9 {Year}: 2023 Nov 16 暂无{DOI}: 10.1177/02184923231205966 {Abstract}: A 47-year-old man with a history of hypertension was found to have a prominent aortic knob on routine chest X-ray and was referred to our hospital. Enhanced computed tomography angiography showed severe flexion at the proximal descending aorta with chronic type B dissection localized to the flexion region. Graft replacement of the distal aortic arch was performed. Surgical management of chronic pseudocoarctation dissection is sparsely reported in the literature because of its rare occurrence. We present an operative case of a patient with chronic dissection of distal aortic arch pseudocoarctation.
