However, in portopulmonary hypertension(PoP H) patients, advanced liver dysfunction and/or thrombocytopenia often makes the use of intravenous epoprostenol challenging. Here we report the cases of two WHO-FC Ⅳ PoP H patients who were successfully treated with a combination of two oral vasodilators used to treat PAH: ambrisentan and tadalafil. Oral vasodilator therapy using a combination of ambrisentan and tadalafil may be a safe and effective therapeutic option for WHO-FC Ⅳ PoP H patients and should be considered for selected patients with severe and rapidly progressing PoP H.展开更多
