Risk of aortic dissection in patients with ascending aorta aneurysm: a new biological, morphological, and biomechanical network behind the aortic diameter

Thoracic aortic aneurysm represents a deadly condition, particularly when it evolves into rupture and dissection. Proper surgical timing is the key to positively influencing survival of patients with this pathology. According most recent guidelines, ascending aorta size ? 55 mm rate growth 0.5 cm per year are important factors for indication. Nevertheless, lot evidence show that ruptures dissections might occur also in small aorta. In review, we sought analyze new biological morphological network behind diameter need be considered order identify portion thoracic who at increased risk complications, despite current guidelines not advising intervention group
