Therapeutic Strategies for Infectious Multiple Aortic Aneurysms: Thoracoabdominal Aortic Aneurysm Treatment Using a Fenestrated Stent-Graft

Recently, it has been reported that a fenestrated stent graft is an effective option in the treatment of pararenal artery abdominal aortic aneurysm. We report the case of a 72-year-old male patient with multiple aortic aneurysms in the distal arch, thoracoabdominal aorta, right common iliac artery, as well as a pararenal abdominal aortic aneurysm. The patient was found to have a mass with a tendency of rapid expansion within a month from its discovery. Because it was a saccular aneurysm with a tendency of rapid expansion and wide spread, the risk of rupture was judged to be high, and surgical treatment became necessary. One-stage treatment was desirable; therefore, endovascular treatment with a fenestrated stent graft was selected. Four fenestrations were made to a stent graft for the celiac artery, superior mesenteric artery, and bilateral renal arteries. The postoperative computed tomography (CT) showed no branch occlusion or endoleak, and the 2-year postoperative CT showed the shrinkage and subsequent disappearance of the aortic aneurysm at the treatment site. For extensive aortic aneurysm, including pararenal artery abdominal aortic aneurysms, one-stage treatment with fenestrated stent graft was considered to be effective as a treatment strategy.
