<p>The present invention provides a noninvasive method for improving collateral circulation to tissue at risk of ischemia or ischemic necrosis. Improved collateral circulation is obtained by applying a growth factor from the PDGF family to the area at or around an occluded blood vessel causing compromised direct circulation to the affected tissue. The present invention further provides a method for anastomosing one or more divided blood vessels using a growth factor from the PDGF family. Preferably, the growth factor is administered locally to the end(s) of the divided blood vessel(s) at or around the area where a single divided blood vessel is attached to tissue of an organ at risk of ischemia.</p> |
