Arterialized venous 'flow through' flaps have already been used in clinical practice by various surgeons.

An experimental model is proposed to assess the various types of venous flap, based on an enlarged version of an epigastric flap in the rat. This flap may be very large in size and has a quadruple vascular pedicle, which makes it ideal for the reproduction of particularly complex flow models, such as the ones under examination. Our experimental model has shown that there are substantial differences between purely venous and arterialized 'flow through' flaps.

Abstract
Arterialized venous 'flow through' flaps have already been used in clinical practice by various surgeons. New potential has also been identified through the study of venous territories in the skin, which has demonstrated that there are far more sites containing two superficial veins than those containing an artery and a vein. Finally, in the rat, it has been shown that this type of flap can be created by running a vein attached to the subcutaneous tissue through them. An experimental model is proposed to assess the various types of venous flap, based on an enlarged version of an epigastric flap in the rat. This flap may be very large in size and has a quadruple vascular pedicle, which makes it ideal for the reproduction of particularly complex flow models, such as the ones under examination. Our experimental model has shown that there are substantial differences between purely venous and arterialized 'flow through' flaps. None of the former type of flap survived in any of the ten rats on which it was grafted, while only two of the ten arterialized flaps manifested dermonecrosis related problems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
