Aortic arch lesions mainly include aneurysm and dissection. Traditional open surgery requires thoracotomy and cardiopulmonary bypass, which is huge traumatic and has a high incidence of complications. Therefore, elderly patients or those with high surgical risks often cannot tolerate the operation. With its minimally invasive and effective advantages, the endovascular technique has become the first choice for the treatment of the descending thoracic aorta aneurysm or type B dissection. However, due to the characteristics of arch lesions near the heart, many important branch vessels, and fast blood flow, endovascular treatment still faces many challenges. At present, some endovascular treatment techniques applied to the aortic arch are off-label use and the long-term efficacy is not clear. The branched endovascular arch repair technique is more in line with the normal anatomical structure and blood flow state of the human body. It usually does not require brain protection measures. Therefore, it is a hot research direction of scholars at home and abroad.
