Successful remodeling and endovascular repair of a ruptured type B chronic aortic dissection 12 years after primary surgery.

A 70-year-old woman with a medical history of descending aorta replacement for chronic type B aortic dissection 12 years prior was admitted to our hospital with sudden back pain and hemoptysis. The patient was diagnosed with ruptured residual dissected thoracic aortic aneurysm and underwent emergent endovascular treatment. Two TAG thoracic endoprosthesis of different sizes were used to accommodate the discrepancy in size of the true lumen, resulting in a successful closure of the entry tear and hemostasis, without any damage to the intima. Computed tomography performed 3 months after surgery revealed successful remodeling of the remaining aorta. Thoracic endovascular aortic replacement may be considered as an option in the treatment of chronic dissected aortic aneurysm, achieving not only entry closure but possibly remodeling, as well.
