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.

Our results support the use of fasciocutaneous distal flap, vascularized by the ascending branch of the PARP for reconstruction of soft tissue defects in the distal third of the lower limb, malleolar regions and dorsum.

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

LN size without other US morphological and vascular characteristics of LN does not provide enough valid US finding for a reliable preoperative identification of LN with metastatic changes in patients with cutaneous melanoma.
