Follow up of Patients With Aortic Aneurysm by Dosage of Circulant Endothelial Progenitor Cells

Follow up of Patients With Aortic Aneurysm by Dosage of Circulant Endothelial Progenitor Cells

Exclusion Criteria:

1. Unstable coronary artery disease.
2. Congenital heart disease.
3. Any evolving infectious syndrome or viral infection (HIV, HBV or HCV).
4. Any chronic inflammatory or autoimmune disease.
5. Prior administration of G-CSF; EPO; GM-CSF.
6. Liver failure.
7. Prior oncologic disease or ongoing cancer with a life expectancy < 1 year.
