Off-the-shelf multi-branch endograft for the treatment of chronic type B aortic dissection with prior thoracic endovascular aortic repair.

We report a case of a 51-year-old male with a history of chronic type B aortic dissection status post thoracic endovascular aortic repair who presented with a progressive thoracoabdominal aortic aneurysm. The patient underwent a successful off-the-shelf multibranch stent graft procedure for complete sealing of the false lumen, with extensions into visceral and renal arteries. This case highlights the advantages of this technique, offering comprehensive sealing of entry tears and enhanced false lumen thrombosis. Preoperative computed tomography imaging, intraoperative angiographic images, and postoperative computed tomography findings are presented to illustrate the procedure's effectiveness and clinical outcomes.
