Portopulmonary hypertension and hepatopulmonary syndrome

Abstract: Portopulmonary hypertension (POPH) and hepatopulmonary syndrome (HPS) are two frequent complications of liver disease, with prevalence among liver transplant candidates of 6% and 10%, respectively. Both conditions result from a lack of hepatic clearance of vasoactive substances produced in the splanchnic territory. Subsequently, these substances cause mainly pulmonary vascular remodeling and some degree of vasoconstriction in POPH with resulting elevated pulmonary pressure and right ventricular dysfunction.

“…Патогенез ГПС недостаточно изучен, однако известно, что прекапиллярная вазодилатация в легких играет ключевую роль в развитии заболе-вания, так как вызывает нарушение вентиляци-онно-перфузионных соотношений и увеличение альвеолярно-артериального кислородного гра-диента [1,16,17]. Вследствие прекапиллярной вазодилатации молекулы кислорода не достигают эритроцитов, находящихся в центре расширенно-го капилляра [18] (рис.…”

“…Для под-тверждения диагноза используют контрастную трансторакальную эхокардиографию (ЭхоКГ) и перфузионную сцинтиграфию (ПС) легких с использованием макроагрегированного альбу-мина, меченного 99m Тс [1]. Снижение сатурации менее 97% в вертикальном положении тела при дыхании атмосферным воздухом свидетельству-ет о наличии гипоксемии.…”
