ABSTRACT

A 73-year-old man had Stanford type B acute aortic dissection 11 years before. He had underwent thoracoabdominal aortic replacement due to thoracoabdominal aneurysm nine years before and hemiarch aortic replacement due to Stanford type A acute aortic dissection four years before. We performed surgery because the dissecting aortic aneurysm in the distal arch has enlarged. We selected thoracic endovascular aortic repair( TEVAR) because of reoperation, but the true lumen of the descending aorta was highly narrowed, we had to deploy stent-grafts into the false lumen. Since the proximal and distal parts of endovascular thoracic stent-grafts were deployed into the previously implanted Dacron grafts, we could deploy them without vascular injury. If both proximal and distal parts of stent-grafts can be deployed into vascular prosthesis, deploying the stent-grafts into the false lumen may be a feasible option.

ABSTRACT

Mechanical thrombectomy has been proposed to expand the treatment time window and enhance revascularization. However, it is unclear whether its use can be extended to patients with occlusions in acute aortic dissection, especially the thoracic aorta. A 55-year-old man underwent graft replacement for acute aortic dissection type A. On postoperative day 2, he developed stroke and computed tomography showed occlusion of the right middle cerebral artery. Mechanical thrombectomy was performed by transbrachial approach. Although successful recanalization was achieved, he suffered hemorrhagic stroke. Since there is no other effective treatment and the neurologic outcome with conservative management is poor, we consider mechanical thrombectomy to be a viable therapeutic option for the treatment of postoperative stroke in patients with acute aortic dissection type A. However, further study is warranted regarding the safety of this technique.
