case_images: Preoperative contrast-enhanced CT (3-dimensional and stretch curved planar reconstruction). CT reveals type B aortic dissection and a thoracoabdominal aortic aneurysm, an abdominal aortic aneurysm, and a right common iliac artery aneurysm. Red arrows indicate the proximal tears. Yellow dotted arrows represent distal tears. CT, computed tomography

case_images: The true lumen of the thoracoabdominal aorta was narrow (Fig. 1).
case_images: Pre-EVAR-contrast-enhanced CT and post-EVAR-angiography. A Distal surgical graft with a double-barrel anastomosis below the renal artery and a large entry at the same site. B The inferior mesenteric artery branches from the false lumen. C, D Re-entry at the right iliac artery bifurcation and termination of the dissection. *: indicate true lumen. Contrast immediately after EVAR. Angiography reveals no obvious endoleak. EVAR, endovascular aortic repair; CT, computed tomography

case_images: Fig2
case_images: The false lumen was ventral, with the inferior mesenteric artery branching from the false lumen (Fig. 2 Pre EVAR). Following posterior dilatation of each part, angiography revealed no obvious endoleak, and the surgical procedure was complete (Fig. 2 Post EVAR).
case_images: Pre- and postoperative CT images. Changes in diameter of abdominal aortic and right common iliac artery aneurysms. CT showing aneurysm shrinkage. CT, computed tomography

case_images: One-year follow-up showed that the abdominal aortic aneurysm decreased from 52.1 to 49.5 mm in maximum diameter, and the right common iliac artery aneurysm decreased from 39.7 to 38.2 mm in maximum diameter on CT; the patient was doing well (Fig. 3).
