Imaging of a patient undergoing ISF. (A) The preoperative CTA indicated a definite diagnosis of aortic dissection in the patient, and the dissection flap was close to the LSA. (B) On follow-up CTA, the position of the stent graft was confirmed to be good, with no evidence of endoleak or stent graft stenosis. (C) Preoperative CTA transverse section scan confirmed the involvement of the LSA by AD. (D) On the follow-up CTA transverse section scan, significant expansion of the true lumen and thrombosis of the false lumen could be observed. ISF, in situ fenestration; CTA, computed tomography angiography; LSA, left subclavian artery; AD, aortic dissection.
