Vascular graft for the replacement of the upper abdominal ascending aorta and of the aortic arch

摘要

A vascular graft suitable for the replacement of the upper abdominal ascending aorta and of the aortic arch is described. This graft bears a number of peripheral branches ending in convergent orifices. In the course of surgical operations, the proposed vascular graft is used in order to achieve continuity of blood supply to the "noble" organs of the organism (the liver, the kidneys, etc.) which are susceptible to irreversible damage should blood supply be interrupted for long time periods. The immediate restoration of blood supply is achieved by the insertion of the above-mentioned orifices of the branches of the graft into the respective arteries, following the insertion and securing of the proximal end of the graft which is provided with a rigid ring and a protruding semi-rigid part into the proximal stump of the aorta.
