Flap necrosis is still a significant complication in all types of flap surg
ery, The effect of parenteral pentoxifylline and nitroglycerin in improving
survival of ischemic skin flaps was tested in Wistar rats. In the control
group (n = 15) the mean viable length of the flaps was calculated to be 6.1
60 +/- 0.936, and non-necrotic flap area was found to be 1859.1 +/- 269.3,
In the group treated with pentoxifylline and nitroglycerin (n = 15), the me
an viable length of the flap was calculated to be 6.907 +/- 0.617, and the
mean nonnecrotic flap area was found to be 2078.5 +/- 172.7, In this study
results showed that the use of parenteral pentoxifylline and topical nitrog
lycerin is effective on skin flap survival.
