Post-reperfusion syndrome PRS is an acute, transitory hemodynamic cardiovascular collapse phenomenon which happens following liver revascularisation, leading to reduced arterial pressure, systemic vascular resistance and myocardial contractility accompanied by increased filling pressures, pulmonary vascular resistance manifest by increased mean pulmonary arterial pressure42 and bradycardia, 43 which could suddenly evolve to cardiac arrest.44 PRS occurs in around 30% of liver transplants and classically has a hemodynamic pattern characterised by a fall in mean arterial pressure of more than 30% of pre-reperfusion values, lasting for more than one minute and occurring during the first five minutes of reperfusion.
El síndrome post reperfusión es un fenómeno hemodinámico agudo y transitorio de colapso cardiovascular que sucede con la revascularización, ocurriendo disminución de la presión arterial, de la resistencia vascular sistémica y de la contractilidad miocárdica acompañada de aumento de las presiones de llenamiento, de la resistencia vascular pulmonar manifestada por aumento de las presiones de la arteria pulmonar media y en cuña 30 y bradicardia31, pudiendo evolucionar súbitamente a paro cardíaco32 .
