case_images: Computed tomography angiography (CTA) revealed multiple tears at the origin of the ascending aorta and around the renal artery, with post-dissection aneurysm formation (Supplementary Figures S1A,C). The abdominal aorta diameter decreased from 51 to 38 mm, while the true lumen diameter increased from 20 to 27 mm (Supplementary Figures S1B,D).

case_images: All visceral arteries originate from the true lumen (Supplementary Figure S2A). Follow-up CTA revealed persistent blood flow in the mid to distal false lumen of the abdominal aorta, with distal narrowing, indicating the possibility of re-embolization therapy (Supplementary Figures S2B,C). The abdominal aorta diameter decreased from 52 mm to 47 mm, while the true lumen increased from 24 mm to 28 mm (Supplementary Figure S2D).

case_images: (A) Preoperative CTA showed blood flow in false lumen of aorta. (B) Intraoperative angiography showed the false lumen opacification in abdominal aorta. (C) Angiography showed no opacification of the false lumen after AVPs (white arrow) and coils (blue arrow) placement. (D) 3-month post-surgery CTA shows AVP in abdominal aorta.

case_images: Multiple tears were located at the level of the celiac trunk and bilateral iliac arteries (Figure 3A). Under local anesthesia, the false lumen is accessed through an intimal tear in the left iliac artery (Figure 3B). Angiography confirmed no false lumen opacification (Figure 3C). The diameter of the abdominal aorta decreased from 57 mm to 47 mm, while the diameter of the true lumen increased from 22 mm to 37 mm (Figure 3D).

case_images: Procedure 1: Under local anesthesia, the false lumen was accessed via a tear in the right iliac artery (Figure 4A). II with diameters of 16 mm, 20 mm, and 22 mm were placed to embolize the false lumen (Figure 4B). Intraoperatively, angiography revealed that several lumbar arteries arose from the false lumen. Angiography showed post-dissection aortic aneurysm formation, and the tear was located in the infrarenal abdominal aorta and right iliac artery (Figure 4C). Intraoperative angiography reveals patent visceral arteries and no false lumen opacification (Figure 4D).
