First, the absence of contraindications must be confi rmed. Hidden viral infections must be ruled out, and the patient's cytomegalovirus CMV status must be verified. It is vitally important to perform a CAT scan and/or MRI to rule out the presence of lesions indicating hepatocellular carcinoma or thrombosis of the portalmesenteric axis.
Se confirma la ausencia de contraindicaciones, se descartan infecciones virales ocultas, se verifica el estado inmunológico contra citomegalovirus CMV y es de vital importancia descartar con TAC o RNM la presencia de lesiones sugestivas de CHC y trombosis del eje porto-mesentérico.
