Description

<p>A 63-year-old woman underwent ascending aortic graft replacement for acute type A aortic dissection at the age of 62. The dissecting aortic aneurysm of distal arch gradually expanded. An entry was found in the distal aortic arch, and the celiac artery, superior mesenteric artery, and right renal artery arosed from the false lumen. Entry closure with TEVAR was underwent while measuring the false lumen pressure. She was discharged without complications on the 11th postoperative day. The computed tomography at 1 year after the operation revealed that the false lumen in the distal arch was occluded by thrombus, and the diameter of the aneurysm was reduced. Measurement of false lumen pressure in TEVAR for chronic dissecting thoracic aortic aneurysm with the abdominal branches arising from the false lumen was useful in assessing mesenteric ischemia during the operation.</p>
