ABSTRACT
Resumen: La hipertensión portopulmonar (HPP) es una entidad poco frecuente a nivel mundial, aunque se desconocen los datos epidemiológicos en México. Sin embargo, las enfermedades crónicas del hígado son muy prevalentes en mexicanos. La HPP es el 4.◦ subtipo en frecuencia del grupo de la hipertensión arterial pulmonar. Su diagnóstico está dentro de 2 escenarios: los pacientes con sospecha de hipertensión pulmonar y los candidatos a trasplante hepático ortotópico (THO). Tanto el ecocardiograma como el cateterismo cardiaco derecho son determinantes para el diagnóstico en ambos escenarios. La HPP es un reto para el THO, pues aumenta la mortalidad perioperatoria de manera importante. El uso de terapia específica es la piedra angular de este padecimiento, como una medida para poder mejorar el desenlace de los que llegan a ser candidatos a un THO con HPP moderada a grave. Es importante reconocer que la HPP puede llegar a ser una contraindicación para el THO. Hasta el momento el papel del trasplante combinado pulmón-hígado o corazón-pulmón-hígado como una medida de curación de la enfermedad vascular pulmonar en pacientes con HPP es incierto. © 2016 Instituto Nacional de Cardiolog´ıa Ignacio Cha´vez.

Abstract: Portopulmonary hypertension (PPH) is a rare condition worldwide, although epidemiological data are unknown in Mexico. However, chronic liver diseases are very prevalent in Mexico. PPH is the 4th subtype in frequency in the group of pulmonary arterial hypertension. Its diagnosis is made within 2 scenarios: patients with suspected pulmonary hypertension and candidates for orthotopic liver transplantation (OLT). Both echocardiogram and a right cardiac catheterisation are crucial for diagnosis in both cases. PPH is a challenge for OLT, since it can significantly increase perioperative mortality. The use of specific therapy is the cornerstone of this disease, as a measure to improve the outcome of those who become candidates for OLT with moderate to severe PPH. It is important to recognise that PPH can be a contraindication to OLT. The role of lung-liver transplantation or heart-lung-liver transplantation as a measure to heal pulmonary vascular disease in patients with PPH is still uncertain.© 2016 Instituto Nacional de Cardiolog´ıa Ignacio Cha´vez.
