Endoluminal stent-graft repair in a patient with coarctation of the aorta and previous iatrogenic type B aortic dissection and expanding pseudoaneurysm.

Purpose: To report endoluminal repair of aortic coarctation in a patient with a chronic type B aortic dissection presenting with an expanding pseudoaneurysm after failure of surgical repair.

Case Report: This 30-year-old man with a congenital coarctation of the aorta suffered an iatrogenic type B aortic dissection during angiography at the age of 6. Emergent surgery at that time included a left subclavian artery-to-distal thoracic aorta surgical conduit; the coarctation itself was not repaired. The patient presented 24 years after the surgery with a chronic distal extension of the dissection and a pseudoaneurysm severely compressing the aortic true lumen; the disrupted surgical conduit drained into the false lumen. In a novel approach, the true aortic lumen was intentionally occluded, and the surgical conduit was secured with stent-grafts to successfully exclude the pseudoaneurysm from the circulation.

Conclusion: Type B dissection and coarctation of the aorta, in the setting of complex aortic pathology and comorbidities, can be treated with an endovascular approach.
