摘要:
A vascular endoprosthesis "soft elephant trunk" for hybrid treatment of thoracic aortic dissection is proposed, which is a tube made of dacron with a diameter of 20-32 mm, characterized in that the tube is 200 mm long, while the tube is supported by nitinol wires with sinusoidal corona wires, repeating two times around the perimeter 50 mm below the proximal end of the vascular endoprosthesis, arranged in parallel with six rows in length at intervals of 20 mm, in addition, contains an additional lower nitinol wire "crown" in the form of nosoids, repeated around the perimeter 16 times, the diameter of all nitinol wires of the "crown" decreases distally: the top three nitinol wires of the "crown" - 0.5 mm, the three lower ones - 0.4 mm, the additional lower nitinol wire "crown" - 0, 25 mm is located 15 mm above the distal end of the vascular endoprosthesis.The proposed vascular endoprosthesis "soft elephant trunk" for the hybrid treatment of thoracic aortic dissection differs from the existing E-Vita Open PLUS practice in the absence of the part represented by the vascular prosthesis for simultaneous reconstruction of the arch and ascending aorta. To replace the ascending and the aortic arch, any diameter-optimal linear or multi-jaw prosthesis that connects to the vascular endoprosthesis with a soft elephant trunk for hybrid treatment of thoracic aortic dissection using the proximal end, represented by a 50 mm vascular prosthesis fragment, can be used. The vascular endoprosthesis "soft elephant trunk" for the hybrid treatment of stratification of the thoracic aorta provides stabilization in the true channel of the stratified aorta, makes it possible to reduce the load and traumatic effect on the stratified intima due to a downward decrease in the diameter and elasticity of nitinol wires.Предлагается сосудистый эндопротез "мягкий хобот слона" для гибридного лечения расслоения грудной аорты, представляющий собой трубку из дакрона диаметром 20-32 мм, отличающийся тем, что
