Endovascular exclusion of thoracic aorta with domestic covered stent can be used. Many medical device companies in China have developed and produced thoracic aortic covered stent systems, which have been proved to be effective and safe in the treatment of thoracic aortic aneurysm through strict clinical trials and regulatory approval. For example, a study found that the success rate and complication rate of domestic thoracic aortic covered stent system in clinical application are equivalent to those of imported products. Therefore, it is safe to use domestic covered stent for endovascular exclusion of thoracic aorta.
