Scallop Technique of Urgent Endovascular Repair for Symptomatic Throacoabdominal Aortic Aneurysm With a Ready-Made Device

A 72-year-old woman had a large thoracoabdominal aortic aneurysm (TAAA) with abdominal pain. This aneurysm involved the celiac artery and the superior mesenteric artery (SMA). The risk of open surgery was very high due to severe comorbidity, and there was no appropriate distal attachment for thoracic endovascular repair (TEVAR) with ready-made devices. Therefore, TEVAR with the scallop technique was performed in this urgent setting. A scallop was created in a Talent thoracic stent graft. The aneurysm was successfully excluded, and perfusion in the SMA was preserved using this scalloped endograft. The scallop technique with a ready-made device may be one of the treatment options for urgent TAAA.
