ABSTRACT

Tissue transfer is a widely used procedure in plastic surgery. The readiness of donor sites of great extension is limited by the vascular architecture. The application of the delay phenomenon and the current concepts of revascularization and angiogenesis allow reconstructive surgeons to build new kinds of sophisticated and exquisite flaps. An experimental model of vascular transporter was carried out to prefabricate a great musculocutaneus flap in rat. The revascularization capacity a torn piece made up of muscle trapezius, was compared through a delay of skeletal muscle of the latissimus dorsi muscle as muscle-vascular pedicle with a non delayed control. The muscle-vascular pedicle showed the best revascularization in the torn piece compound prefabricated with 90% ± 10% of survival of the torn piece (p ‹0.001), while the not delayed one showed total necrosis in 85.8% of the control group. The histologic review of the pattern showed visual evidence of revascularization and formation of an angiogenic pedicle among the dorsal muscle and the trapezius that provides survival to the later. The reliable possibility is established set up to elaborate muscle-muscular compound torn pieces by means of the delay techinique and the development of an angiogenic pedicle.
