Mentioned aortic diameterchanges are shown in Tables 4. and 5.Conclusions1. The study shows that the innovative aorticprostheses do not change in diameter after twomonth from the surgery.2. Surgery like abdominal aorta transplantation doesnot cause significant variations in blood pressureduring post operative period.3. To find out later reactions to synthetic vasculargraft, further observations are recommended.References1. Alcantara E.M., Marshall L.M., Rodriguez V.V., Rosado C.F.
