Abstract
- A perfusion deficit of the aortic branch vessels in a patient with a type B aortic dissection is a challenging complication, as it leads to hemodynamic instability and doubles the mortality rate; however, the optimal management strategy in these cases remains controversial. Although surgical repair is still performed as the standard, endovascular approaches have been used recently as alternatives because of the high rate of perioperative complications. Herein, we report a patient with a type B aortic dissection and compromised renal and iliac arteries who was successfully treated by thoracic endovascular repair and insertion of a percutaneous stent. In addition, we adopted the chimney technique to preserve blood flow to the left subclavian artery due to the short proximal landing zone.
