Endovascular treatment strategies for complex thoracic aortic diseases

Complex thoracic aortic diseases are of diverse forms, for which endovascular therapy may convert the untreatable conditions into treatable ones mainly by means of prolonging the proximal landing zone. The specific measures include chimney stent technique, hybrid surgery, in-situ fenestration and pre-fenestration technologies, and also include the selection of the appropriate aortic stent and the branched stent technology which will be used in clinical settings in the near future. The choice of various methods is mainly based on the location and characteristics of the lesion and the patient’s economic conditions, and the experience of the surgeon also should be considered.
