Research Abstract

we evaluated experimentally the feasibility of transferring a pedicled venous flap with perivenous areolar tissue into an ectopic site, and investigated the role of each vein, the perivenous areolar tissue and nerve in the viability of pedicle venous flaps. Five groups of flaps were created Group 1 : (N=11) containing perivenous areolar tissue and a draining vein ; Group 2 : (N=10) perivenous areolar tissue, a draining vein and nerve ; Group 3 : (N=1O) only perivenous areolar tissue ; Group 4 : (N=6) perivenous areolar tissue and nerve ; Group 5 : (N=6) only draining vein.
Macroscopic, angiographic and histological assessments were performed 14 days after transfer. Total survival area including superficial necrosis of Group 1,2,3,4 and 5 were 52.7%, 825%, 0%, 225% and 0% respectively. There were significant differences in mean survival area and mean total survival area including superficial necrosis between Group 1 and Group 2 (p(]SY.di-substituted right.[)O.O5). In contrast, all flaps in Group 3 and Group 5 became necrotic. These data suggest that a preserved vein is the necessary condition and additional arterial flow through the preserved nerve and a small vascular network within the areolar tissue may play an important role in flap survival.
