Highly selective A(1) -adenosine-agonist (2-chloro-N6-cyclopentyladenosine) and reduction of flap necrosis in adipocutaneous flaps in rats.
Background: The 2-chloro-N6-cyclopentyladenosine (CCPA) was proven to be a protective factor in ischemic reperfusion injury in myocardium and to reduce the infarct size in the heart. The purpose of this study was to determine whether flap necrosis could be reduced by intravenous administration of CCPA.
Methods: Fifty-six male Wistar rats were divided into 4 experimental groups. An epigastric adipocutaneous flap was raised, and the area of flap necrosis was assessed for all groups on the fifth postoperative day with planimetry software.
Results: The control group had a significantly lower rate of flap necrosis than the ischemic control group (p < .05). The nonischemic CCPA group had a significantly lower rate of flap necrosis than the nonischemic control group (p < .05). The ischemic CCPA group had a highly significant (p < .0001) rate of lower flap necrosis than the ischemic control group.
Conclusion: Our data show that reduction of flap necrosis can be achieved both with and without ischemic periods by intravenous administration of CCPA.
