“…The sooner this cascade is reversed, the greater the chance for tissue viability, since these are time-dependent phenomena. 12 In this context, some drugs are being used to attempt to minimize and prevent such events. This study sought to analyze the effects of streptokinase (a thrombolytic) and allopurinol (a xanthine oxidase inhibitor) in skin flaps submitted to prolonged ischemia.…”

“…It is believed that normothermic venous ischemia for eight hours leads to irreversible necrosis in epigastric skin flaps in rats, 12 though there are exceptions in similar experimental models. 32 Global ischemia (venous and arterial), on the other hand, is more easily tolerated.…”

“…estes eventos de hipercoagulubilidade, lesão por radicais livres, agregação leucocitária, edema intersticial, vasoespasmo e estase, ocasionam a trombose irreversível da microcirculação. Quanto antes esta cascata for revertida, maior será a chance de viabilidade do tecido, visto que esses fenômenos são tempo dependentes 12 . Neste contexto, alguns fármacos estão sendo empregados na tentativa de minimizar e prevenir estes eventos.…”

“…Denomina-se este fenômeno de não perfusão, devido à trombose da microcirculação e não por trombose do pedículo 30,31 . O retalho epigástrico foi escolhido no presente estudo,por ter irrigação sanguínea axial através dos vasos epigástricos superficiais inferiores facilmente acessíveis conforme descrito por Sasaki e pang, sendo um modelo amplamente utilizado em pesquisas científicas [10][11][12][13][14][15]37,[39][40][41][42][43] relacionadas ao estudo da isquemia/reperfusão. …”
