Current limitations to the experimentation on patients with peripheral arterial disease push the development of different preclinical strategies. We investigated both duration of ischemia and blood flow recovery in mouse models of partial femoral artery ligation.


Male BALB/c mice were used. The ligation over needle method involved placing a suture needle over the femoral artery, ligating over it and then removing the needle. The transfixation method involved transfixing the approximate center of the femoral artery and then tying the suture. Laser Doppler Perfusion Imaging was used to assess perfusion every 3rd day until 42 days after the procedure.


Ligation over needle method: Immediately post procedure, mean perfusion was -71.87% ± 4.43. Then mean difference in perfusion remained below the base line reading on days 3, 6, 9, and 12. From day 15 on wards mean perfusion progressively improved remaining near base line. Transfixation Method: Immediately post procedure mean perfusion was -70.82% ± 4.73. Mean perfusion improved following the procedure on days 3 and 6; a plateau followed this on days 9, 12 and 15. From day 15 onwards perfusion progressively improved remaining well below base line until crossing it on day 36.


The currently described models do not pose major improvements over previously described methods.
