Case report demonstrates successful endovascular repair of a symptomatic suture aneurysm from aortic isthmus restenosis, indicating a viable alternative to high-risk open reintervention.
After operative treatment of aortic isthmus stenoses, late complications, such as aneurysm formation or aortic restenosis, might occur, with relevant morbidity and mortality rates during open surgical reintervention. We report on the endovascular repair of a symptomatic suture aneurysm caused by an aortic isthmus restenosis by thoracic aortic stent graft implantation and additional intraoperative balloon dilatation. Based on our experience, endovascular repair of thoracic aortic aneuryms caused by native aortic isthmus stenosis or postcoarctation restenosis is a valuable treatment option, especially in symptomatic patients with an imminent risk of rupture or a difficult immediate transthoracic surgical approach. Long-term follow-up is required to assess the durability of the stent graft treatment.
