“…The total flap necrosis occurs in all AVF's, despite previous T-T micro-anastomosis. A high percentage of AVF's necrosis is similar to the results reported by other authors (Cho et al, 1998;Moshammer et al, 2003) and on pedicle vein flap on rats (Cutting et al, 1980;Daniel et al, 1990;Sano et al, 2003;Baser et al, 2005). CONCLUSION Non-conventional circulation in the flap is a relatively new and cheaper method in plastic and reconstructive surgery, that has been underestimated by many surgeons.…”

The aim of this study was to test a new experimental design of venous system arterialization on the rabbit ear arterialized venous flap (AVF) model. Total number of 10 "Big Chinchila" rabbits were divided in two experimental groups. On both ears of the five rabbits (Group 1) we have performed our original method of venous system arterialization with microsurgical arterialization of the central artery and vein with the preservation of central and peripheral vascular perfusion; at both ears of five rabbits (Group 2) we have performed AVF according to Byan et al., (1995). Vital AVF surface and necrosis percentage were determined in both experimental groups at day 1 and day 14 and results were compared using Student t-test. The results of our experiment indicate that our new experimental design of the AVF on rabbit ear model has better hemodynamic conditions, improves AVF survival and gives significantly bigger vital flap surface at 14 days after venous system arterialization

Surface enlargement of a new arterialised venous flap by the surgical delay method

et al. 2014

Analysis of previous experimental models on the rabbit ear, non-delayed and delayed (to enlarge flap surface) led us to conclusion that previously created experimental models of non-delayed AVF are hemodynamically negative. Our experimental non-delay AVF model is hemodynamically more positive than previously created models of non-delay AVF and provides better conditions for AVF survival and enlargement of vital flap surface of elevated flap. On the other hand, surgical delay method significantly enlarges vital surface of AFF.

“…However, venous flaps are not as reliable as conventional flaps. If a reliable venous island flap is prepared, then various flaps can be designed on the surface of the body using the subcutaneous veins [4,5]. Yilmaz et al [6] showed on rabbit ears that the venous flaps were not as reliable as the conventional flaps, and a greater number of venous pedicles were associated with improved flap survival.…”

The aim of the present study was to investigate the effect of ischaemic preconditioning compared with the surgical delay procedure in an effort to increase the survival rate of single pedicle island venous flaps. Eighteen male Wistar albino rats (250-350 g) were included. A 3 × 4 cm flap was planned at the right lower abdomen of the rat. Superficial epigastric vein constituted the pedicle of the flap. The rats were divided into three groups, each consisting of six rats. In the control group, a single pedicle venous island flap was elevated on each rat and no other surgical procedure was performed. In the ischaemic preconditioning group, ischaemic preconditioning was performed and, in the surgical delay procedure group, the surgical delay technique was performed before flap elevation. The mean necrosis areas were 56.85 ± 14.60%, 28.73 ± 15.60%, and 12.08 ± 3.65% in the control, ischaemic preconditioning, and surgical delay procedure groups, respectively. The necrosis areas were significantly smaller in the ischaemic preconditioning group and surgical delay procedure groups compared to the control group (p = 0.004 and p < 0.001, respectively). The necrosis areas were similar in the ischaemic preconditioning and surgical delay procedure groups. Histopathological parameters including necrosis, abscess formation, and skin ulceration scores were significantly lower in the ischaemic preconditioning group than in the control group, whereas the study groups were similar. In conclusion, ischaemic preconditioning may serve as an adjuvant technique in increasing venous island flap viability.
