The prosthesis currently used to treat aortic dissection is in the form of a tube surrounded by a thin nitinol scaffold that allows it to open and retain its shape. In hybrid surgeries, while the aortic valve, ascending aorta and arch are replaced, the thoracic aorta is stabilized by placing a hybrid prosthesis with a nitinol frame. However, scaffold pressure on the surrounding aortic tissues may cause post-operative complications such as pressure sores on the prosthesis edge and aortic tear.
A new generation of aortic prosthesis is being developed in Russia, based on the idea of using a biodegradable material for a scaffold that inserts the prosthesis and dissolves over time. This device is unique and has no analogues in the world. The current prosthesis is a success and good reputation among aortic surgeons, but doctors are trying to avoid negative consequences for patients. Professor Eduard Charchyan, Head of the Department of Reconstructive Cardiovascular Surgery, RNC No. 1 named after Academician BV Petrovsky, spoke about the plans and emphasized that the institute is moving forward and striving for new achievements.
Computational studies and mathematical tests of a new aortic prosthesis model are carried out at the Kurchatov Institute National Research Center. After the successful completion of the “theoretical” modeling phase, animal testing will be carried out. This is an important milestone in the development of the next generation aortic prosthesis.
